GLP-1-ra and heart failure-related outcomes in patients with and without history of heart failure: an updated systematic review and meta-analysis. Clin Res Cardiol 2024; 113:898-909. [PMID: 38252145 DOI: 10.1007/s00392-023-02362-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 12/06/2023] [Indexed: 01/23/2024]
Abstract
AIMS Glucagon-like peptide-1 receptor agonists (GLP1-ra) have shown to reduce cardiovascular (CV) events in patients with diabetes, including heart failure (HF) hospitalizations. However, whether such benefit consistently occurs in patients with history of HF remains uncertain. We performed a systematic review and meta-analysis to assess the impact of GLP1-ra on CV outcomes in patients with and without HF history. METHODS AND RESULTS All randomized, placebo-controlled trials evaluating GLP1-ra and reporting CV outcomes stratified by HF history were searched in Pubmed from inception to November 12th, 2023. The primary outcome was HF hospitalizations. Secondary outcomes included CV death, the composite of CV death and hospitalizations for HF, and major adverse cardiovascular events (MACE). Hazard ratio (HR) and 95% confidence interval (CIs) were used as effect estimates and calculated with a random-effects model. 68,653 patients (GLP1-ra = 34,301, placebo = 34,352) from 10 trials were included. GLP1-ra reduced HF hospitalization (no HF: HR = 0.79, 95% CI 0.63-0.98; HF: HR = 1.00, 95% CI 0.82-1.24, pinteraction = 0.12), CV death (no HF: HR = 0.81, 95% CI 0.71-0.92; HF: HR = 0.97, 95% CI 0.81-1.15, pinteraction = 0.11), and the composite of HF hospitalizations and CV death (no HF: HR = 0.80, 95% CI 0.72-0.89; HF: HR = 1.00 95% CI 0.88-1.15, pinteraction = 0.010) only in patients without history of HF, despite a significant interaction between HF history and treatment effect was detected only for the latter. MACE were reduced in both subgroups without significant interaction between HF history and treatment effect (no HF: HR = 0.86, 95% CI 0.78-0.96; HF: HR = 0.83, 95% CI 0.72-0.95, pinteraction = 0.69). CONCLUSION GLP1-ra do not decrease HF-hospitalization risk, despite a potential benefit in patients without history of HF, but are effective in reducing ischemic events irrespective of the presence of HF.

Differences between cardiogenic shock related to acute decompensated heart failure and acute myocardial infarction. ESC Heart Fail 2023; 10:3472-3482. [PMID: 37723131 PMCID: PMC10682868 DOI: 10.1002/ehf2.14510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 04/13/2023] [Accepted: 08/08/2023] [Indexed: 09/20/2023] Open
Abstract
AIMS The present analysis from the multicentre prospective Altshock-2 registry aims to better define clinical features, in-hospital course, and management of cardiogenic shock complicating acutely decompensated heart failure (ADHF-CS) as compared with that complicating acute myocardial infarction (AMI-CS). METHODS AND RESULTS All patients with AMI-CS or ADHF-CS enrolled in the Altshock-2 registry between March 2020 and February 2022 were selected. The primary objective was the characterization of ADHF-CS patients as compared with AMI-CS. In-hospital length of stay and mortality were secondary endpoints. One-hundred-ninety of the 238 CS patients enrolled in the aforementioned period were considered for the present analysis: 101 AMI-CS (80% ST-elevated myocardial infarction and 20% non-ST-elevated myocardial infarction) and 89 ADHF-CS. As compared with AMI-CS, ADHF-CS patients were younger [63 (IQR 59-76) vs. 67 (IQR 54-73) years, P = 0.01], but presented with higher creatinine [1.6 (IQR 1.0-2.6) vs. 1.2 (IQR 1.0-1.4) mg/dL, P < 0.001], bilirubin [1.3 (IQR 0.9-2.3) vs. 0.6 (IQR 0.4-1.1) mg/dL, P = 0.01], and central venous pressure values [14 mmHg (IQR 8-12) vs. 10 mmHg (IQR 7-14),P = 0.01]. Norepinephrine was the most common catecholamine used in AMI-CS (79.3%), whereas epinephrine was used more commonly in ADHF-CS (65.5%); 75.8% vs. 46.6% received a temporary mechanical support in AMI-CS and ADHF-CS, respectively (P < 0.001). Length of hospital stay was longer in the latter [28 (IQR 13-48) vs. 17 (IQR 9-29) days, P = 0.001]. Heart replacement therapies were more frequently used in the ADHF-CS group (heart transplantation 13.5% vs. 0% and left ventricular assist device 11% vs. 2%, P < 0.01 and 0.01, respectively). In-hospital mortality was 41.1% (38.6% AMI-CS vs. 43.8% ADHF-CS, P = 0.5). CONCLUSIONS ADHF-CS is characterized by a higher prevalence of end-organ and biventricular dysfunction at presentation, a longer hospital length of stay, and higher need of heart replacement therapies when compared with AMI-CS. In-hospital mortality was similar between the two aetiologies. Our data warrant development of new management protocols focused on CS aetiology.

SCAI stage reclassification at 24 h predicts outcome of cardiogenic shock: Insights from the Altshock-2 registry. Catheter Cardiovasc Interv 2023; 101:22-32. [PMID: 36378673 PMCID: PMC10100478 DOI: 10.1002/ccd.30484] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 09/27/2022] [Accepted: 11/02/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Cardiogenic shock (CS) includes several phenotypes with heterogenous hemodynamic features. Timely prognostication is warranted to identify patients requiring treatment escalation. We explored the association of the updated Society for Cardiovascular Angiography and Interventions (SCAI) stages classification with in-hospital mortality using a prospective national registry. METHODS Between March 2020 and February 2022 the Altshock-2 Registry has included 237 patients with CS of all etiologies at 11 Italian Centers. Patients were classified according to their admission SCAI stage (assigned prospectively and independently updated according to the recently released version). In-hospital mortality was evaluated for association with both admission and 24-h SCAI stages. RESULTS The overall in-hospital mortality was 38%. Of the 237 patients included and staged according to the updated SCAI classification, 20 (8%) had SCAI shock stage B, 131 (55%) SCAI stage C, 61 (26%) SCAI stage D and 25 (11%) SCAI stage E. In-hospital mortality stratified according to the SCAI classification at 24 h was 18% for patients in SCAI stage B, 27% for SCAI stage C, 63% for SCAI stage D and 100% for SCAI stage E. Both the revised SCAI stages on admission and at 24 h were associated with in-hospital mortality, but the classification potential slightly increased at 24-h. After adjusting for age, sex, lactate level, eGFR, CVP, inotropic score and mechanical circulatory support [MCS], SCAI classification at 24 h was an independent predictor of in-hospital mortality. CONCLUSIONS In the Altshock-2 registry the utility of SCAI shock stages to identify risk of in-hospital mortality increased at 24 h after admission. Escalation of treatment (either pharmacological or with MCS) should be tailored to achieve prompt clinical improvement within the first 24 h after admission. Registration: http://www.

Impact of hemoglobin levels at admission on outcomes among elderly patients with acute coronary syndrome treated with low-dose Prasugrel or clopidogrel: A sub-study of the ELDERLY ACS 2 trial. Int J Cardiol 2022; 369:5-11. [PMID: 35907504 DOI: 10.1016/j.ijcard.2022.07.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 07/13/2022] [Accepted: 07/17/2022] [Indexed: 11/15/2022]
Abstract
Hemoglobin (Hb) levels have emerged as a useful tool for risk stratification and the prediction of outcome after myocardial infarction. We aimed at evaluating the prognostic impact of this parameter among patients in advanced age, where the larger prevalence of anemia and the higher rate of comorbidities could directly impact on the cardiovascular risk. METHODS All the patients in the ELDERLY-2 trial, were included in this analysis and stratified according to the values of hemoglobin at admission. The primary endpoint of this study was cardiovascular mortality within one year. The secondary endpoints were all-cause mortality, MI, Bleeding Academic Research Consortium (BARC) type 2-3 or 5 bleeding, any stroke, re-hospitalization for cardiovascular event or stent thrombosis (probable or definite) within 12 months after index admission. RESULTS We included in our analysis 1364 patients, divided in quartiles of Hb values (<12.2; 12.2-13.39; 13.44-14.49; ≥ 4.5 g/dl). At a mean follow- up of 330.4 ± 99.9 days cardiovascular mortality was increased in patients with lower Hb (HR[95%CI] = 0.76 [0.59-0.97], p = 0.03). Results were no more significant after correction for baseline differences (adjusted HR[95%CI] = 1.22 [0.41-3.6], p = 0.16). Similar results were observed for overall mortality. At subgroup analysis, (according to Hb median values) a significant interaction was observed only with the type of antiplatelet therapy, but not with major high-risk subsets of patients. CONCLUSIONS Among elderly patients with acute coronary syndrome managed invasively, lower hemoglobin at admission is associated with higher cardiovascular and all-cause mortality and major ischemic events, mainly explained by the higher risk profile.

192 GLP1-RA AND HEART FAILURE-RELATED OUTCOMES IN PATIENTS WITH AND WITHOUT HISTORY OF HEART FAILURE: A SYSTEMATIC REVIEW AND METANALYSIS. Eur Heart J Suppl 2022.

Abstract
Abstract
Background
GLP1-receptor agonists (GLP1-ra) are recently developed anti-diabetic drugs which have shown promising results in phase-3 cardiovascular (CV) outcomes trials in diabetic patients, demonstrating a reduction in major adverse cardiovascular events (MACE) and, possibly, in heart failure (HF) hospitalizations. However, whether these medications improve such outcomes in patients with a history of HF remains unknown.
Methods
All randomized, placebo-controlled trials of GLP1-ra (and predefined/post-hoc analysis) reporting CV outcomes stratified by HF history were searched in Pubmed from inception to August 31st, 2022. The primary outcome was HF hospitalizations. Secondary outcomes included MACE, CV death and a composite of HF hospitalization and CV death. The analysis was performed after stratifying for HF history. Odds-ratio (OR) and 95% confidence interval (CIs) were used as effect estimated and calculated via a random-effects model. P for interaction between subgroups were calculated via meta-regression analysis and a level of p<0.10 was considered as significant.
Results
Data from 6 trials and a total of 40300 patients (n=20127 GLP1-ra group, n=20173 placebo group) were included. GLP1-ra reduced HF hospitalizations in patients without HF history (OR 0.71, 95% CI 0.51-0.99) but had neutral effect on those with previous HF (OR 1.04, 95% CI 0.88–1.22, p-interaction=0.089). CV death was also reduced by intervention only in the group without history of HF (OR 0.81, 95% CI 0.71–0.92), as well as the composite of HF hospitalizations and CV death (OR 0.80, 95% CI 0.72–0.90). Indeed, no difference between treatment arms was found in the HF group for CV death (OR 0.99, 95% CI 0.82–1.18, p-interaction=0.18) and the composite of HF hospitalization or CV death (OR 1.02 95%CI 0.89–1.18, p-interaction=0.073). MACE reduction was similar in patients with (OR 0.87 95% CI 0.72–1.06) and without HF history (OR 0.84 95% CI 0.76–0.93, p-interaction = 0.75).
Conclusion
GLP1-ra do not reduce HF hospitalization and CV death in patients with history of HF, as the benefit on cardiovascular outcomes provided by this anti-diabetic class of drugs seems to be mainly limited to patients without HF history. Future studies focused on HF patients are needed to confirm such findings and clarify the limited efficacy of GLP1-ra in this relevant group of patients.

Abstract
Abstract
Background
Cardiogenic shock (CS) is the most severe form of acute heart failure, characterized by life-threatening end-organ hypoperfusion resulting from a low cardiac output state. Data on epidemiology of CS has been mostly drawn from registries focusing on acute myocardial infarction (AMI). However, recent evidence in a contemporary cohort in North America has shown that more than two thirds of all CS cases were related to causes other than AMI and that these patients had outcomes at least as poor as patients with AMICS.
Purpose
To provide data on profile, management, outcome, and evolution over time of CS patients admitted to ICCU/ICU and to compare them between patients with AMICS and acute decompensated heart failure (ADHF-CS).
Methods
The Altshock-2 Registry is a multicenter national prospective data collection, part of the Italian Altshock-2 program. Recruitment started on 2 March 2020 with 11 Italian Centers contributing to patients' enrolment. A total of 238 patients were hospitalized with confirmed diagnosis of CS between March 2020 and February 2022 in a multicenter national initiative. The mean age of this patient population was 64 years (interquartile range [IQR] 54–74) and 76% were male. Ninety-seven patients (41%) were admitted for AMICS, whereas 84 patients (35.3%) had ADHF-CS; 57 patients (24%) had other causes. As compared to AMICS patients, those admitted for ADHF-CS were younger, but with a higher burden of comorbidities (renal, liver, thyroid disease, atrial fibrillation, anemia), pre-existing decreased ejection fraction and a higher number of chronic drugs. Patients with ADHF-CS had a prevalent cardio-metabolic phenotype upon admission with prevalent congestion. Mechanical ventilation was more commonly used in patients with AMICS, compared to ADHF-CS, along with an increased inotropic score. Conversely, sodium nitroprusside was used in about sixty percent of patients with ADHF-CS. Sixty percent of the included population received a temporary mechanical circulatory support (MCS) device, which was intra-aortic balloon pump (IABP) in the eighty percent of the supported patients. Pulmonary artery catheter was used for monitoring only in the 18% of the included patients whereas an extensive echocardiographic approach was applied. Twenty-one patients (25%) underwent heart replacement therapy in the ADHF-CS patients versus 2 (2%) in the AMICS. Thirty-day mortality occurred in 32 patients (33%) in the AMICS group versus 23 (27%) in the ADHF-CS group (p=0.41).
Conclusions
Different diagnostic approaches and uses of mechanical circulatory support devises and inotropes are implemented in transatlantic settings. Uniform definitions and more homogenous protocols tailored on CS etiologies and clinical and biochemical phenotypes are needed in prospective initiatives in order to effectively compared results and outcome.

Abstract
Abstract
Background
Cardiogenic shock (CS) includes several phenotypes of congestion or hypoperfusion with heterogenous hemodynamic features. Timely prognostication with scoring tools is warranted to identify patients requiring escalation to mechanical circulatory support (MCS) and to avoid futility.
Purpose
Accordingly, we explored the role of the updated Society for Cardiovascular Angiography and Interventions (SCAI) stages classification on in-hospital mortality using a prospective national registry.
Methods
The Altshock-2 Registry includes 237 patients with CS of all etiologies enrolled between March 2020 and February 2022 in 11 Italian Centers. Patients were classified according to the admission SCAI stages (assigned prospectively and independently updated according to the most recently released version); 24-hour re-assessment was prospectively performed in 201 patients. In-hospital mortality was evaluated for association with admission and 24 hours SCAI stages adjusted for the most relevant clinical covariates.
Results
Of the 237 patients included, 20 (8.4%) had SCAI shock stage B, 132 (55.8%) SCAI stage C, 60 (25.3) SCAI stage D and 25 (10.5%) SCAI stage E. Patients in stage B had the worst reclassification at 24-hours, with 42% of them showing worsened status and only 8% improving. In-hospital mortality was 38%. The revised SCAI stages at baseline were not independently associated with in-hospital mortality, whereas the SCAI classification at 24-h correctly and independently predicted mortality (the rate of in-hospital death was 18% for patients in SCAI shock stage B, 27% for SCAI shock stage C, 64% for SCAI shock stage D, 100% for SCAI shock stage E). At the multivariate analysis (adjusted for age, gender, eGFR, inotropic score and MCS) only SCAI classification at 24-hour evaluation was an independent predictor of in-hospital mortality (OR and 95% CI were, respectively, 3.32, 0.36–30.63, p=0.290 for SCAI stage C and 13.07, 1.69–146.3 for SCAI stage D, with E perfectly predicting because all patients died).
Conclusions
The revised SCAI stage classification may improve prognostication only at 24-hour evaluation. Aggressive treatment (either pharmacological or with MCS escalation) should be tailored in order to achieve prompt clinical improvement within the first 24-hours; refractory SCAI stage E at 24 hours portends dismal prognosis.

Abstract
Abstract
Aims
Propafenone is a Class 1C antiarrhythmic drug recommended in the treatment of supraventricular or ventricular tachycardia and paroxysmal atrial fibrillation (AF). Most common cardiological features associated with propafenone intoxication include heart failure and conduction disturbances while other clinical findings range from nausea and vomiting to seizures and coma.
Methods
We report a case of atypical presentation of propafenone intoxication occurred in 88-year-old woman who presented at Emergency Department with severe ECG abnormalities and prevalent acute right ventricular with massive tricuspidalic regurgitation and cardiogenic shock. The patient underwent urgent coronary angiography that revealed a stable 90% coronary plaque that was treated with a single stent and then brought to Intensive Care Unit where she was successfully treated with inotropic and mechanical circulatory support (intra-aortic balloon pump, IABP).
Results
The patient progressively achieved hemodynamic stability with complete ECG normalization and biventricular function recovery.
Conclusions
Our case further expands the vast spectrum of presentations of Class 1c antiarrhythmic drugs overdose. In an emergency setting it is difficult to rule out other causes of cardiogenic shock but propafenone toxicity needs to be suspected in every case of hemodynamic instability in patients in chronical treatment. Patients in chronical treatment with propafenone who have kidney or liver dysfunction might be at higher risk of drug accumulation: in such cases, the real utility of propafenone must be evaluated before therapy initiation.

Association of Sex with Outcome in Elderly Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention. Am J Med 2021; 134:1135-1141.e1.

Abstract
BACKGROUND Worse outcomes have been reported for women, compared with men, after an acute coronary syndrome (ACS). Whether this difference persists in elderly patients undergoing similar invasive treatment has not been studied. We investigated sex-related differences in 1-year outcome of elderly acute coronary syndrome patients treated by percutaneous coronary intervention (PCI). METHODS Patients 75 years and older successfully treated with PCI were selected among those enrolled in 3 Italian multicenter studies. Cox regression analysis was used to assess the independent predictive value of sex on outcome at 12-month follow-up. RESULTS A total of 2035 patients (44% women) were included. Women were older and most likely to present with ST-elevation myocardial infarction (STEMI), diabetes, hypertension, and renal dysfunction; men were more frequently overweight, with multivessel coronary disease, prior myocardial infarction, and revascularizations. Overall, no sex disparity was found about all-cause (8.3% vs 7%, P = .305) and cardiovascular mortality (5.7% vs 4.1%, P = .113). Higher cardiovascular mortality was observed in women after STEMI (8.8%) vs 5%, P = .041), but not after non ST-elevation-ACS (3.5% vs 3.7%, P = .999). A sensitivity analysis excluding patients with prior coronary events (N = 1324, 48% women) showed a significantly higher cardiovascular death in women (5.4% vs 2.9%, P = .025). After adjustment for baseline clinical variables, female sex did not predict adverse outcome. CONCLUSIONS Elderly men and women with ACS show different clinical presentation and baseline risk profile. After successful PCI, unadjusted 1-year cardiovascular mortality was significantly higher in women with STEMI and in those with a first coronary event. However, female sex did not predict cardiovascular mortality after adjustment for the different baseline variables.

Early intra-aortic balloon pump in acute decompensated heart failure complicated by cardiogenic shock: Rationale and design of the randomized Altshock-2 trial. Am Heart J 2021; 233:39-47.

Abstract
BACKGROUND Cardiogenic shock (CS) is a systemic disorder associated with dismal short-term prognosis. Given its time-dependent nature, mechanical circulatory support may improve survival. Intra-aortic balloon pump (IABP) had gained widespread use because of the easiness to implant and the low rate of complications; however, a randomized trial failed to demonstrate benefit on mortality in the setting of acute myocardial infarction. Acute decompensated heart failure with cardiogenic shock (ADHF-CS) represents a growing resource-intensive scenario with scant data and indications on the best management. However, a few data suggest a potential benefit of IABP in this setting. We present the design of a study aimed at addressing this research gap. METHODS AND DESIGN The Altshock-2 trial is a prospective, randomized, multicenter, open-label study with blinded adjudicated evaluation of outcomes. Patients with ADHF-CS will be randomized to early IABP implantation or to vasoactive treatments. The primary end point will be 60 days patients' survival or successful bridge to heart replacement therapy. The key secondary end point will be 60-day overall survival; 60-day need for renal replacement therapy; in-hospital maximum inotropic score, maximum duration of inotropic/vasopressor therapy, and maximum sequential organ failure assessment score. Safety end points will be in-hospital occurrence of bleeding events (Bleeding Academic Research Consortium >3), vascular access complications and systemic (noncerebral) embolism. The sample size for the study is 200 patients. IMPLICATIONS The Altshock-2 trial will provide evidence on whether IABP should be implanted early in ADHF-CS patients to improve their clinical outcomes.

Abstract
Abstract
Background
Patients with acute cardiovascular disease admitted to the Intensive Cardiac Care Unit (ICCU), especially those with more severe critical illness, experiment agitation and delirium during hospitalization. Iatrogenic, environmental, or related to the severity of acute illness factors may concur to determine these two conditions. However, their epidemiological, clinical, and prognostic relevance in this specific clinical context are not well defined, yet. As a result, current recommendations on the evaluation and management of these complications are lacking.
The aim of this prospective, multicenter, observational registry was to evaluate the incidence of agitation and delirium in patients admitted to the ICCU for an acute cardiac event, their in-hospital prognostic impact, and their treatment.
Methods
We enrolled consecutive patients with acute cardiovascular events in four Italian tertiary-care centers. Agitation levels were ranked from Richmond Assessment Sedation Scale (RASS), and the presence of delirium was detected by Confusion Assessment Method-Intensive Care Unit (CAM ICU) at least twice a day and in case of variation of the state of consciousness. The primary endpoint was the incidence of agitation and/or delirium. The secondary endpoints were: 1) the association between these complications and in-hospital outcome and 2) the therapies adopted for their management.
Results
Overall, 723 patients were included in the registry. Of them, 116 (16%) presented agitation and/or delirium during ICCU stay. Delirium subtypes were: 6% hypoactive, 64% hyperactive, and 30% mixed. Patients with agitation/delirium had worse in-hospital outcomes than patients without.. Indeed, they had a higher ICCU mortality (10% vs. 2%; P<0.001) and a higher rate of major complications: ventricular arrhythmias (26% vs. 12%; P<0.001), atrial fibrillation (29% vs. 15%; P<0.001), sepsis (15% vs. 9%; P=0.06), and bleeding (17% vs. 7%; P<0.001). Moreover, they were more frequently treated with mechanical procedures: invasive and non-invasive ventilation (58% vs. 18%; P<0.001), circulatory support (20% vs. 5%; P<0.001), continuous renal replacement therapy (6% vs. 1%; P<0.001). Finally, ICCU length of stay was longer (8 vs. 4 days; P<0.001). The drugs more likely used for agitation treatment were benzodiazepine (32%), dexmedetomidine (31%), opioids (10%), and antipsycotic drugs (1%). Delirium was mainly treated with dexmedetomidine (46%), benzodiazepine (23%), antipsycotic drugs (16%), and opioids (8%).
Conclusions
This study demonstrates that agitation and delirium are frequent complications also in the acute cardiac setting and are associated with poor in-hospital outcome. In this particular context, the treatment of choice and its possible impact on prognosis remain to be established.

Early detection of elevated cardiac biomarkers to optimise risk stratification in patients with COVID-19. Heart 2020; 106:1512-1518. [PMID: 32817312 DOI: 10.1136/heartjnl-2020-317322] [Citation(s) in RCA: 65] [Impact Index Per Article: 16.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 07/16/2020] [Accepted: 07/28/2020] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVE Risk stratification is crucial to optimise treatment strategies in patients with COVID-19. We aimed to evaluate the impact on mortality of an early assessment of cardiac biomarkers in patients with COVID-19. METHODS Humanitas Clinical and Research Hospital (Rozzano-Milan, Lombardy, Italy) is a tertiary centre that has been converted to the management of COVID-19. Patients with confirmed COVID-19 were entered in a dedicated database for cohort observational analyses. Outcomes were stratified according to elevated levels (ie, above the upper level of normal) of high-sensitivity cardiac troponin I (hs-TnI), B-type natriuretic peptide (BNP) or both measured within 24 hours after hospital admission. The primary outcome was all-cause mortality. RESULTS A total of 397 consecutive patients with COVID-19 were included up to 1 April 2020. At the time of hospital admission, 208 patients (52.4%) had normal values for cardiac biomarkers, 90 (22.7%) had elevated both hs-TnI and BNP, 59 (14.9%) had elevated only BNP and 40 (10.1%) had elevated only hs-TnI. The rate of mortality was higher in patients with elevated hs-TnI (22.5%, OR 4.35, 95% CI 1.72 to 11.04), BNP (33.9%, OR 7.37, 95% CI 3.53 to 16.75) or both (55.6%, OR 18.75, 95% CI 9.32 to 37.71) as compared with those without elevated cardiac biomarkers (6.25%). A multivariate analysis identified concomitant elevation of both hs-TnI and BNP as a strong independent predictor of all-cause mortality (OR 3.24, 95% CI 1.06 to 9.93). CONCLUSIONS An early detection of elevated hs-TnI and BNP predicts mortality in patients with COVID-19. Cardiac biomarkers should be systematically assessed in patients with COVID-19 at the time of hospital admission in order to optimise risk stratification.

Abstract
BACKGROUND Despite recent improvements in percutaneous coronary revascularization and antithrombotic therapies for the treatment of acute coronary syndromes, the outcome is still unsatisfactory in high-risk patients, such as the elderly and patients with diabetes. The aim of the current study was to investigate the prognostic impact of diabetes on clinical outcome among patients included in the Elderly-ACS 2 trial, a randomized, open-label, blinded endpoint study carried out at 32 centers in Italy. METHODS Our population is represented by 1443 patients included in the Elderly-ACS 2 trial. Diabetes was defined as known history of diabetes at admission. The primary endpoint of this analysis was cardiovascular mortality, while secondary endpoints were all-cause death, recurrent myocardial infarction, Bleeding Academic Research Consortium type 2 or 3 bleeding, and rehospitalization for cardiovascular event or stent thrombosis within 12 months after index admission. RESULTS Diabetes was present in 419 (29%) out of 1443 patients. Diabetic status was significantly associated with major cardiovascular risk factors and history of previous coronary disease, presentation with non-ST segment elevation myocardial infarction (P = 0.01) more extensive coronary disease (P = 0.02), more advanced Killip class at presentation (P = 0.003), use at admission of statins (P = 0.004) and diuretics at discharge (P < 0.001). Median follow-up was 367 days (interquartile range: 337-378 days). Diabetic status was associated with an absolute increase in the rate of cardiovascular mortality as compared with patients without diabetes [5.5 vs. 3.3%, hazard ratio (HR) 1.7 (0.99-2.8), P = 0.054], particularly among those treated with clopidogrel [HR (95% confidence interval (CI)) = 1.89 (0.93-3.87), P = 0.08]. However, this difference disappeared after correction for baseline differences [Adjusted HR (95% CI) 1.1(0.4-2.9), P = 0.86]. Similar findings were observed for other secondary endpoints, except for bleeding complications, significantly more frequent in diabetic patients [HR (95% CI) 2.02 (1.14-3.6), P = 0.02; adjusted HR (95% CI) = 2.1 (1.01-4.3), P = 0.05]. No significant interaction was observed between type of dual antiplatelet therapy, diabetic status and outcome. CONCLUSION Among elderly patients with acute coronary syndromes, diabetic status was associated with higher rates of comorbidities, more severe cardiovascular risk profile and major bleeding complications fully accounting for the absolute increase in mortality. In fact, diabetes mellitus did not emerge as an independent predictor of survival in advanced age.

Impact of body mass index on clinical outcome among elderly patients with acute coronary syndrome treated with percutaneous coronary intervention: Insights from the ELDERLY ACS 2 trial. Nutr Metab Cardiovasc Dis 2020; 30:730-737.

Abstract
BACKGROUND AND AIM Elderly patients are at increased risk of hemorrhagic and thrombotic complications after an acute coronary syndrome (ACS). Frailty, comorbidities and low body weight have emerged as conditioning the prognostic impact of dual antiplatelet therapy (DAPT). The aim of the present study was to investigate the prognostic impact of body mass index (BMI) on clinical outcome among patients included in the Elderly-ACS 2 trial, a randomized, open-label, blinded endpoint study comparing low-dose (5 mg) prasugrel vs clopidogrel among elderly patients with ACS. METHODS AND RESULTS Our population is represented by 1408 patients enrolled in the Elderly-ACS 2 trial. BMI was calculated at admission. The primary endpoint of this analysis was cardiovascular (CV) mortality. Secondary endpoints were all-cause death, recurrent MI, Bleeding Academic Research Consortium (BARC) type 2 or 3 bleeding, and re-hospitalization for cardiovascular reasons or stent thrombosis within 12 months after index admission. Patients were grouped according to median values of BMI (<or ≥ 25.7 kg/m2). BMI was associated with hypertension, diabetes, hypercholesterolemia, estimated glomerular filtration rate and hemoglobin (p < 0.001), and inversely with age (p = 0.005). Overweight patients displayed larger use of diuretics at admission (p = 0.03), aspirin pre-randomization (p = 0.01) and radial access (p = 0.04). At a median follow-up of 367 [337-378] days, BMI did not affect CV mortality in the overall population 4% vs 3.8%; adjusted HR [95%CI] = 2.3 [0.8-6.5], p = 0.12. Similar findings were observed for our secondary efficacy and safety endpoints. Results did not change when considering separately higher risk subsets of patients, (female gender, diabetics, ST-segment elevation myocardial infarction or the type of DAPT treatment allocation), with no significant interaction between these population characteristics and BMI. CONCLUSIONS Among elderly patients with ACS, BMI did not condition the survival or the risk of major cardiovascular and bleeding complications. The results were consistent across several patient risk categories.

Abstract
BACKGROUND In-hospital cardiac arrest is a major cause of death in European countries, and survival of patients remains low ranging from 20% to 25%. AIMS The purpose of this study was to assess healthcare professionals' knowledge on cardiopulmonary resuscitation among university hospitals in 12 European countries and correlate it with the return of spontaneous circulation rates of their patients after in-hospital cardiac arrest. METHODS AND RESULTS A total of 570 healthcare professionals from cardiology, anaesthesiology and intensive care medicine departments of European university hospitals in Italy, Poland, Hungary, Belgium, Spain, Slovakia, Germany, Finland, The Netherlands, Switzerland, France and Greece completed a questionnaire. The questionnaire consisted of 12 questions based on epidemiology data and cardiopulmonary resuscitation training and 26 multiple choice questions on cardiopulmonary resuscitation knowledge. Hospitals in Switzerland scored highest on basic life support (P=0.005) while Belgium hospitals scored highest on advanced life support (P<0.001) and total score in cardiopulmonary resuscitation knowledge (P=0.01). The Swiss hospitals scored highest in cardiopulmonary resuscitation training (P<0.001). Correlation between cardiopulmonary resuscitation knowledge and return of spontaneous circulation rates of patients with in-hospital cardiac arrest demonstrated that each additional correct answer on the advanced life support score results in a further increase in return of spontaneous circulation rates (odds ratio 3.94; 95% confidence interval 2.78 to 5.57; P<0.001). CONCLUSION Differences in knowledge about resuscitation and course attendance were found between university hospitals in 12 European countries. Education in cardiopulmonary resuscitation is considered to be vital for patients' return of spontaneous circulation rates after in-hospital cardiac arrest. A higher level of knowledge in advanced life support results in higher return of spontaneous circulation rates.

Abstract
RATIONALE In the exploratory Phase II STEM-AMI (Stem Cells Mobilization in Acute Myocardial Infarction) trial, we reported that early administration of G-CSF (granulocyte colony-stimulating factor), in patients with anterior ST-segment-elevation myocardial infarction and left ventricular (LV) dysfunction after successful percutaneous coronary intervention, had the potential to significantly attenuate LV adverse remodeling in the long-term. OBJECTIVE The STEM-AMI OUTCOME CMR (Stem Cells Mobilization in Acute Myocardial Infarction Outcome Cardiac Magnetic Resonance) Substudy was adequately powered to evaluate, in a population showing LV ejection fraction ≤45% after percutaneous coronary intervention for extensive ST-segment-elevation myocardial infarction, the effects of early administration of G-CSF in terms of LV remodeling and function, infarct size assessed by late gadolinium enhancement, and myocardial strain. METHODS AND RESULTS Within the Italian, multicenter, prospective, randomized, Phase III STEM-AMI OUTCOME trial, 161 ST-segment-elevation myocardial infarction patients were enrolled in the CMR Substudy and assigned to standard of care (SOC) plus G-CSF or SOC alone. In 119 patients (61 G-CSF and 58 SOC, respectively), CMR was available at baseline and 6-month follow-up. Paired imaging data were independently analyzed by 2 blinded experts in a core CMR lab. The 2 groups were similar for clinical characteristics, cardiovascular risk factors, and pharmacological treatment, except for a trend towards a larger infarct size and longer symptom-to-balloon time in G-CSF patients. ANCOVA showed that the improvement of LV ejection fraction from baseline to 6 months was 5.1% higher in G-CSF patients versus SOC (P=0.01); concurrently, there was a significant between-group difference of 6.7 mL/m2 in the change of indexed LV end-systolic volume in favor of G-CSF group (P=0.02). Indexed late gadolinium enhancement significantly decreased in G-CSF group only (P=0.04). Moreover, over time improvement of global longitudinal strain was 2.4% higher in G-CSF patients versus SOC (P=0.04). Global circumferential strain significantly improved in G-CSF group only (P=0.006). CONCLUSIONS Early administration of G-CSF exerted a beneficial effect on top of SOC in patients with LV dysfunction after extensive ST-segment-elevation myocardial infarction in terms of global systolic function, adverse remodeling, scar size, and myocardial strain.

Mitral Valve Stenosis after Transcatheter Aortic Valve Replacement: Case Report and Review of the Literature. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2019; 20:1196-1202.

Abstract
Mitral stenosis is a rare and potentially severe complication of transcatheter aortic valve replacement (TAVR). Given the anatomic coupling and interdependence of the aortic and mitral valves, it comes by itself that procedures (either surgical or percutaneous) involving the aortic valve imply the risk of altering mitral valve function. Indeed, transcatheter aortic prostheses may impair adequate anterior mitral leaflet (AML) opening, especially when implanted in a "low" position, thus resulting in high transvalvular gradients. Hereby, we report the case of a 71-year-old male with symptomatic severe aortic stenosis and a history of previous surgical mitral valve repair who underwent TAVR with a self-expandable prosthesis. Notwithstanding an acceptable angiographic position, the prosthetic frame was shown to interfere with the AML, as evidenced by augmented transmitral gradients; nonetheless, pulmonary artery pressures remained unchanged, and the patient experienced symptomatic improvement. Therefore, a conservative approach was chosen and the patient was discharged home after medical therapy optimization. Moreover, we provide a review of the available literature regarding the incidence, predictors and possible management of this infrequent complication.

Abstract
INTRODUCTION Acute coronary syndromes (ACS) have been classified according to the finding of ST-segment elevation on the presenting electrocardiogram, with different treatment strategies and practice guidelines. However, a comparative description of the clinical characteristics and outcomes of acute coronary syndrome elderly patients undergoing percutaneous coronary intervention during index admission has not been published so far. METHODS Retrospective cohort study of patients enrolled in the Elderly ACS-2 multicenter randomized trial. Main outcome measures were crude cumulative incidence and cause-specific hazard ratio (cHR) of cardiovascular death, noncardiovascular death, reinfarction, and stroke. RESULTS Of 1443 ACS patients aged >75 years (median age 80 years, interquartile range 77-84), 41% were classified as ST-elevation myocardial infarction (STEMI), and 59% had non-ST-elevation ACS (NSTEACS) (48% NSTEMI and 11% unstable angina). As compared with those with NSTEACS, STEMI patients had more favorable baseline risk factors, fewer prior cardiovascular events, and less severe coronary disease, but lower ejection fraction (45% vs 50%, P < .001). At a median follow-up of 12 months, 51 (8.6%) STEMI patients had died, vs 39 (4.6%) NSTEACS patients. After adjusting for sex, age, and previous myocardial infarction, the hazard among the STEMI group was significantly higher for cardiovascular death (cHR 1.85; 95% confidence interval [CI], 1.02-3.36), noncardiovascular death (cHR 2.10; 95% CI, 1.01-4.38), and stroke (cHR 4.8; 95% CI, 1.7-13.7). CONCLUSIONS Despite more favorable baseline characteristics, elderly STEMI patients have worse survival and a higher risk of stroke compared with NSTEACS patients after percutaneous coronary intervention.

Abstract
Background:
Elderly patients are at elevated risk of both ischemic and bleeding complications after an acute coronary syndrome and display higher on-clopidogrel platelet reactivity compared with younger patients. Prasugrel 5 mg provides more predictable platelet inhibition compared with clopidogrel in the elderly, suggesting the possibility of reducing ischemic events without increasing bleeding.
Methods:
In a multicenter, randomized, open-label, blinded end point trial, we compared a once-daily maintenance dose of prasugrel 5 mg with the standard clopidogrel 75 mg in patients >74 years of age with acute coronary syndrome undergoing percutaneous coronary intervention. The primary end point was the composite of mortality, myocardial infarction, disabling stroke, and rehospitalization for cardiovascular causes or bleeding within 1 year. The study was designed to demonstrate superiority of prasugrel 5 mg over clopidogrel 75 mg.
Results:
Enrollment was interrupted, according to prespecified criteria, after a planned interim analysis, when 1443 patients (40% women; mean age, 80 years) had been enrolled with a median follow-up of 12 months, because of futility for efficacy. The primary end point occurred in 121 patients (17%) with prasugrel and 121 (16.6%) with clopidogrel (hazard ratio, 1.007; 95% confidence interval, 0.78–1.30;
P
=0.955). Definite/probable stent thrombosis rates were 0.7% with prasugrel versus 1.9% with clopidogrel (odds ratio, 0.36; 95% confidence interval, 0.13–1.00;
P
=0.06). Bleeding Academic Research Consortium types 2 and greater rates were 4.1% with prasugrel versus 2.7% with clopidogrel (odds ratio, 1.52; 95% confidence interval, 0.85–3.16;
P
=0.18).
Conclusions:
The present study in elderly patients with acute coronary syndromes showed no difference in the primary end point between reduced-dose prasugrel and standard-dose clopidogrel. However, the study should be interpreted in light of the premature termination of the trial.

Abstract
BACKGROUND Epidemiological studies have shown a higher risk of cardiovascular mortality associated with early menopause, but the relation between menopausal age and extent of coronary artery disease after menopause is unknown. We assessed the relation between menopausal age and extent of coronary disease in postmenopausal women with an acute coronary syndrome. METHODS A prospective study was conducted in patients ≥55 years old undergoing coronary angiography for an acute coronary syndrome. Enrollment was stratified by sex (women/men ratio 2:1) and age (55-64, 65-74, 75-85, and >85 years). Women were administered menopause questionnaires during admission. An independent core lab quantified coronary artery disease extent using the Gensini Score, which classifies both significant (>50%) and nonsignificant lesions. Linear correlation was used to appraise the association between the Gensini score and menopausal age. RESULTS We enrolled 675 patients, 249 men and 426 women (mean age 74 years). The mean Gensini score was 60 ± 36 in men vs 50 ± 32 in women (P <.001), being higher among men at any age. The median menopausal age of women was 50 years. Risk factors and age at first acute coronary syndrome were identical among women below and above the median menopausal age. The Gensini score in women showed a weak association with age (R = 0.127; P = .0129), but not with menopausal age (R = 0.063; P = .228). At multivariable analysis, ejection fraction, female sex, and ST elevation myocardial infarction were independent predictors of the Gensini score in the overall population. CONCLUSIONS Menopausal age was not associated with the extent of coronary artery disease. Age at first acute coronary syndrome presentation, risk factors, and prior cardiovascular events were not affected by menopausal age. (The LADIES ACS study: NCT01997307).

Abstract
BACKGROUND Elderly patients display higher on clopidogrel platelet reactivity as compared with younger patients. Treatment with prasugrel 5mg has been shown to provide more predictable and homogenous antiplatelet effect, as compared with clopidogrel, suggesting the possibility of reducing ischemic events after an acute coronary syndrome (ACS) without increasing bleeding. STUDY DESIGN The Elderly-ACS 2 study is a multicenter, randomized, parallel-group, open-label trial designed to demonstrate the superiority of a strategy of dual antiplatelet treatment using a reduced 5-mg daily dose of prasugrel over a standard strategy with a daily clopidogrel dose of 75mg in patients older than 74years with ACS (either ST- or non-ST-elevation myocardial infarction) undergoing early percutaneous revascularization. The primary end point is the composite of all-cause mortality, myocardial reinfarction, disabling stroke, and rehospitalization for cardiovascular causes or bleeding within 1 year. Taking advantage of the planned size of 2,000 patients, the secondary objective is to assess the prognostic impact of selected prerandomization variables (age, sex, diabetic status, serum creatinine level, electrocardiogram changes, abnormal troponin levels, basal and residual SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery [SYNTAX] score). CONCLUSION The Elderly-ACS 2 study is a multicenter, randomized trial comparing a strategy of dual antiplatelet therapy with a reduced dose of prasugrel with a standard dose of clopidogrel in elderly patients with ACS undergoing percutaneous revascularization (the Elderly ACS 2 trial: NCT01777503).

Eleven-year trends in gender differences of treatments and mortality in ST-elevation acute myocardial infarction in northern Italy, 2000 to 2010. Am J Cardiol 2014; 114:336-41. [PMID: 24925728 DOI: 10.1016/j.amjcard.2014.05.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2014] [Revised: 05/06/2014] [Accepted: 05/06/2014] [Indexed: 10/25/2022]
Abstract
The aim of this study was to assess recent trends in hospital mortality and in the treatment techniques for patients with ST-segment elevation myocardial infarction according to gender. Data on hospitalizations for ST-segment elevation myocardial infarction from 2000 to 2010 were extracted from hospital discharge record databases (International Classification of Diseases, Ninth Revision, Clinical Modification, codes) in the Lombardy Region of Italy. The impact of female gender on in-hospital mortality was assessed by multivariable regression after adjusting for invasive approach use (i.e., coronary angiography, angioplasty or coronary artery bypass graft), age, and co-morbidities. A total of 89,562 patients, men (66.5%) and women (33.5%), were enrolled. The use of an invasive approach increased over time in both sexes although it was higher in men (from 54.9% in 2000 to 91.9% in 2010 in men; from 36.8% in 2000 to 72.0% in 2010 in women). This pattern was driven by the subgroup of patients aged ≥75 years, whereas differences between sexes were not observed in patients <65 years and were small in patients aged 65 to 74 years. In-hospital mortality presented a small decrease from 7.6% in 2000 to 6.2% in 2010 in men (p for trend = 0.004), whereas it remained higher and substantially constant over time in women (16.6% in 2000, 15.5% in 2010, p for trend = 0.09). At multivariable regression, female gender did not emerge as an independent predictor of mortality (p = 0.13). However, a significant gender-age interaction was found, with female gender being a significant predictor of increased mortality in patients aged ≥75 years (odds ratio [OR] 1.33) while predicting a reduced mortality in patients aged <75 years (OR 0.93, p for interaction <0.0001). The use of an invasive approach was an independent predictor of mortality (OR 0.23, p <0.0001), the magnitude of mortality reduction being higher in men than in women and in patients aged <75 years than in those aged ≥75 years. In conclusion, a weak temporal trend in mortality reduction is observed in men only, which is driven by patients aged ≥75 years. In-hospital mortality remains higher in women than in men, although female gender is not a significant predictor of mortality. Despite temporal increases in the use of an invasive approach, women are more often treated conservatively.

Abstract
AIM The aim of the study was to detect early predictors of neurological recovery and evaluate one year survival related to neurological status at discharge in patients (pts) admitted after out of hospital cardiac arrest (OHCA). METHODS Sixty-three consecutive pts with OHCA from any cardiac cause, admitted to our cardiac intensive care unit, were classified according to survival and cerebral performance category (CPC) scale from 1 to 4 at hospital discharge. Pre-hospital and emergency room (ER) variables were analyzed to identify early predictors of neurological recovery as defined CPC=1-2. RESULTS Overall in-hospital survival was 60%. Sixty-eight and 32% of survivors were classified as CPC 1-2 and CPC 3-4 respectively. During one year follow-up 96% of patients classified as CPC 1-2 survived and 100% of CPC 3-4 died. Emergency crew witnessing, performance of cardio pulmonary resuscitation (CPR) by witnesses, the call for chest pain, no history of heart disease and a Glasgow coma scale (GCS) of ≥9 on arrival to the ER, were more frequent in patients classified as CPC 1-2 and times from "OHCA to return of spontaneous circulation (ROSC)", from "emergency medical system (EMS) arrival to ROSC" and "first DC shock to ROSC" were also significantly shorter in these patients. The time of first DC shock to ROSC in pts who presented with rhythm in ventricular fibrillation and the time from OHCA to ROSC in pts with witnessed OHCA were an independent predictors of neurological recovery. CONCLUSION Forty-one percent of pts admitted to our tertiary centre after OHCA were discharged with CPC 1-2 and at one year follow-up 96% of these were alive, while all pts classified as CPC 3-4 died. Easily documented information such as the time from OHCA to ROSC and the time of first shock to ROSC are early independent predictors of neurological recovery.

Abstract
AIM Transcatheter aortic valve implantation (TAVI) became an attractive alternative to surgery for patients with severe aortic stenosis and high operative risk. The first multicenter randomized trial, conducted in such high risk cohort, showed 20% reduction in mortality in the group treated with TAVI compared to those treated with medical therapy (30.7% vs. 50.7% P=0.001) and a non-inferiority of TAVI compared to traditional valve surgical replacement for all-cause mortality at 1 year with, similar improvement of symptoms and physical performance. However, mortality rate of TAVI remains high (20-30% at one year). The purpose of this prospective single center study was to identify predictors of mortality and adverse events in patients undergoing TAVI in order to be able to select the ones who benefit most from the procedure. METHODS Between June 2009 and June of 2011, 118 patients with severe aortic stenosis treated with TAVI at IRCCS Humanitas Clinical Institute were included in a prospective registry. Pre procedural clinical and ecocardiographic evaluations, surgical risk estimation, and procedural complications, defined by VASC criteria, were recorded. Clinical and echocardiographic evaluations were performed at 1, 6 and 12 months after the implants. To investigate the predictors of mortality, clinical and anatomical characteristics of alive patients were compared with those of death ones at one month and one year follow-up. RESULTS The procedural success occurred in 92.4% of procedures; vascular complications (33%), bleeding complications (22%), postimplant paravalvolar grade ≥2 AR (20.4%) a new permanent pacemaker implant (19.7%), were the most common complications. Survival for the whole cohort at 30 days was 6.8%, survival at one year was 82.2%. In the logistic regression test, one month mortality was significantly adversely affected by the renal functional status (odd ratio 0.9356), by a previous history of coronary artery bypass grafting (odd ratio 39) and by the mean aortic annular diameter (odd ratio 0.512) (P=0.0005). One year mortality was influenced by high EuroSCORE (odd ratio 1.0399) and the presence of hemodynamically significant prosthetic regurgitation (odd ratio 3.8438). CONCLUSION TAVI procedure, in high risk patients with critical aortic stenosis, can be accomplished with low procedural mortality. The worst outcome affects particularly patients with renal insufficiency and previous coronary bypass. However, the long-term mortality remains high due to the poor baseline conditions, mainly related to co-morbidity and to the presence of residual post-procedural aortic insufficiency.

Mortality and ST resolution in patients admitted with STEMI: the MOMI survey of emergency service experience in a complex urban area. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2012; 1:192-9.

Abstract
BACKGROUND Since 2001, the urban area of Milan has been operating a network among 23 cardiac care units, the 118 dispatch centre (national free number for medical emergencies), and the county government health agency called Group for Prehospital Cardiac Emergency. METHODS AND RESULTS In order to monitor the network activity, time to treatment, and clinical outcome, a periodic survey, called MOMI(2), was repeated two or three times a year. Each survey lasted 30 days and was repeated in comparable periods. Data were stratified for hospital admission mode. We collected data concerning 708 consecutive ST-elevation myocardial infarction (STEMI) patients (male 72.6%; mean age 64.4 years). In these six surveys, we observed a high rate of primary percutaneous coronary intervention (73.2%) and a mortality rate of 6.3%. Using advanced statistical models, we identified age, Killip class, and the symptom onset-to-balloon time as most relevant prognostic factors. Nonparametric test showed that the modality of hospital admittance was the most critical determinant of door-to-balloon time. 12-lead ECG tele-transmission and activation of a fast track directly to the catheterization laboratory are easy action to reduce time to treatment. CONCLUSIONS The experience of the Milan network for cardiac emergency shows how a network coordinating the community, rescue units, and hospitals in a complex urban area and making use of medical technology contributes to the health care of patients with STEMI.

Abstract
OBJECTIVES We assessed the relation between female sex and sirolimus-eluting stent (SES) use on long-term outcomes in acute myocardial infarction. BACKGROUND There are no data on sex-specific differences in long-term benefit of SES use compared with bare-metal stent (BMS) use among patients undergoing primary percutaneous coronary interventions. METHODS We performed a post hoc analysis of the MULTISTRATEGY trial. Hazard ratios (HRs) of events with 95% CI for sex and stent type were computed using Cox proportional regression with adjustment for confounders. RESULTS A total of 744 patients, 64 years old (55-73 years old), 179 (24.1%) women, were enrolled. After a follow-up of 1,080 days, SES use was associated with a significant reduction of major adverse cardiovascular events, that is, the composite of all-cause death, reinfarction, or clinically driven target vessel revascularization (TVR) (13.9% vs 23.6%, adjusted HR 0.62, 95% CI 0.41-0.94, P = .026) and of TVR (6.1% vs 15.1%, adjusted HR 0.35, 95% CI 0.19-0.63, P < .001) in men. Conversely, SES use was not associated to a better outcome among women (major adverse cardiovascular events 21.9% in SES vs 18.2% in the BMS group, adjusted HR 1.27, 95% CI 0.53-3.02, P = .59; TVR 6.6% vs 9.1%, adjusted HR 0.62, 95% CI 0.17-2.21, P = .46). CONCLUSIONS In this analysis, the clinical benefit of SES use, over BMS, at 3-year follow-up was restricted to men and was not observed among women.

Abstract
BACKGROUND AND OBJECTIVES Patients treated with percutaneous coronary intervention receive aspirin and P2Y12 ADP receptor inhibitors to reduce thrombotic complications. The choice of methodology for monitoring the effects of treatment and assessing its efficacy is still a topic of debate. We evaluated how decreased P2Y12 function influences platelet aggregate (thrombus) size measured ex vivo. METHODS AND RESULTS We used confocal videomicroscopy to measure in real time the volume of platelet thrombi forming upon blood perfusion over fibrillar collagen type I at a wall shear rate of 1500 s(-1). The average volume was significantly smaller in 31 patients receiving aspirin and clopidogrel (19) or ticlopidine (12) than in 21 controls, but individual values were above the lower limit of the normal distribution, albeit mostly within the lower quartile, in 61.3% of cases. Disaggregation of platelet thrombi at later perfusion times occurred frequently in the patients. Vasodilator-stimulated phosphoprotein phosphorylation, reflecting P2Y12 inhibition, was also decreased in the patient group, and only 22.6% of individual values were above the lower normal limit. We found no correlation between volume of thrombus formed on collagen fibrils and level of P2Y12 inhibition, suggesting that additional and individually variable factors can influence the inhibitory effect of treatment on platelet function. CONCLUSIONS Measurements of platelet thrombus formation in flowing blood reflects the consequences of antiplatelet therapy in a manner that is not proportional to P2Y12 inhibition. Combining the results of the two assays may improve the assessment of thrombotic risk.

Abstract
AIM To assess the prognostic value of admission plasma glucose (APG) respect to clinical variables and inflammatory markers in a selected population of non-diabetic patients with ST elevation myocardial infarction (STEMI) treated with primary angioplasty (primary coronary intervention, PCI). METHODS A total of 188 consecutive non-diabetic STEMI patients undergoing primary PCI were divided into four quartiles based on APG (<117, 117-140, 141-170, >170 mg/dL). Combined end-point of major adverse cardiac events (MACE) was defined as death, acute heart failure, re-infarction, unstable angina or inducible ischemia. RESULTS Event-free survival from MACE was significantly (P<0.001) correlated with APG quartiles and decrease from the lowest to the highest: 6 months event-free survival was 89.3%, 77.4%, 59.1%, 42.5%. Patients with higher APG were characterized by a significantly higher Killip class (P<0.001), higher serum creatinine (P<0.05) on admission, and a lower rate of thrombolysis in myocardial infarction (TIMI) 3 flow after PCI (P<0.05). Multivariate analysis showed APG>170 mg/dL (hazard ratio [HR] 2.39, 95% confidence interval [CI] 1.24 to 4.65, P<0.01), admission high-sensitivity C-reactive protein level (HR 1.19, 95% CI 1.07 to 1.31, P<0.001), white blood cells count (HR 1.07, 95% CI 1.00 to 1.14, P<0.04) and heart rate (HR 1.02, 95% CI 1.00 to 1.04, P<0.02) to be independent predictors of MACE. CONCLUSION Admission glycemia and inflammatory markers are independent predictors of MACE in the mid-term follow-up in non-diabetic STEMI treated with primary PCI. Further investigations are needed to study the pathogenesis of stress hyperglycaemia, interactions with mechanisms of inflammation and whether early and aggressive treatment with insulin may influence outcome of primary PCI.

Abstract
Drug-eluting stents (DES) have significantly reduced the rates of in-stent restenosis (ISR). As previously observed with bare-metal stents (BMS), either patient's clinical characteristics and lesion morphology may influence the risk of recurrence even with DES. In this review we will focus on the most recent available data on clinical settings where DES efficacy on long-term outcomes are largely unknown. In particular, we report on very complex lesions (bifurcations, small vessels, chronic total occlusions, in-stent restenosis) myocardial infarction, multivessel disease, treatment of bypass graft and of unprotected left main disease. Several issues are still open on DES routinary use for these indications, mainly as far as stent thrombosis is concerned. Recent pathological studies show that DES are characterized by chronic inflammatory infiltrates and delayed endothelialization. Therefore, this effect could translate in a ''vulnerable period'' for thromboses longer than with BMS. Even though large meta-analysis have excluded higher rates of stent thrombosis with DES rather than with BMS, few cases of unusual very late stent thrombosis have been described, pointing out that this problem seems to be still unsolved. Although DES provide better angiographic outcomes in each clinical setting, further randomized studies are running to assess their safety and efficacy on currently off-label indications.

Abstract
The association between admission electrocardiogram and 6-month change in left ventricular function and volume was assessed in 200 patients who had acute myocardial infarction that was treated with primary percutaneous coronary intervention. Logistic regression analysis indicated peak creatine phosphokinase-MB, number of Q-wave leads, QRS interval distortion, wall motion score index, and angiographic Thrombolysis In Myocardial Infarction flow grade as predictors of no functional recovery and QRS interval distortion and Thrombolysis In Myocardial Infarction flow grade as predictors of left ventricular remodeling.

Abstract
In patients with acute ST-elevation myocardial infarction (STEMI), in order to shorten the time to definitive treatment, it is essential to coordinate the intervention between the local healthcare system and the hospitals. In 1999, a Working Group for Prehospital Emergency in Cardiology was established in Milan, and a network for 12-lead ECG transmission between advances life support (ALS) ambulances, the headquarter of 118 Rescue Service and the Coronary Care Units (CCU) or Divisions of Cardiology was developed: between February 1, 2001 and May 1, 2005, 6821 patients with suspected heart attack were rescued and their ECG recorded and transmitted (177 patients/month, 20% of them with an ST-segment shift, 11% ST-segment elevation, 9% non-ST-segment elevation, 24% with normal ECG). The rate of false positive automatic diagnosis of acute myocardial infarction was 0.3%, the rate of false negative was 0.8%. Forty-six patients with ventricular fibrillation underwent DC-shock. After May 1, 2004, clinical data of patients with STEMI transferred to the hospitals by ALS ambulances were reported in a database: 82% of the 89 patients were treated with primary angioplasty. The time (median, interquartile ranges) between ECG arrival to the CCU and the ECG report was 2 min (1-5), between ECG arrival to the CCU and patient arrival to the hospital was 34 min (24-42), between ECG arrival to the CCU and primary angioplasty was 69 min (50-93); the door-to-balloon time was 33 min (22-60). The telephone ECG transmission has been demonstrated to be a useful and rapid tool, easy to use; the automatic ECG diagnosis was accurate. In patients with STEMI the telephone ECG transmission shortened the time of delivery of therapy, helped to recover arrhythmic complications, allowed both the coordination between the 118 System and the Divisions of Cardiology and the implementation of the triage for primary angioplasty. Increasing the technological level of the service will be the next step of the program: the protocol will be upgraded in order to increase the number of patients rescued, to shorten the time of operation and to administer prehospital fibrinolytic therapy in selected patients.

Abstract
BACKGROUND The incidence of late severe heart failure after primary angioplasty is not clear and few data are available about the clinical prognostic predictors of this event. The aims of our study were a) to evaluate the incidence of cardiac death and heart failure after an extensive acute myocardial infarction treated with primary angioplasty, and b) to identify, among clinical, ECG, functional, and angiographic variables, the outcome predictors and their incremental prognostic value. METHODS Two hundred and thirty-three patients with ST-segment elevation in > or = 4 leads, without cardiogenic shock, underwent primary angioplasty within 12 hours of symptom onset and were prospectively followed up for a median of 21 months for the combined endpoint of cardiac death and heart failure. The effects of clinical, ECG, functional, and angiographic data on the combined endpoint were evaluated using Cox's analysis. Separate models were developed including all variables of a given model plus significant variables of previous models to reproduce the usual clinical information flow. RESULTS Twelve (5%) deaths and 23 (10%) heart failures occurred. Diabetes (hazard ratio [HR] 6.46, 95% confidence interval [CI] 1.99-20.98) and peak creatine kinase-MB (HR 1.002, 95% CI 1.001-1.004 per unit increment), wall motion score index (HR 1.46, 95% CI 0.35-6.15 per 0.1 unit increment), and TIMI flow grade < 3 after angioplasty (HR 5.35, 95% CI 2.04-14.02) were the only significant and independent prognostic indicators. ECG information did not improve the model, whilst functional and angiographic data provided incremental prognostic value over clinical information. CONCLUSIONS At mid-term follow-up, extensive acute myocardial infarction patients undergoing primary angioplasty have a moderate heart failure event rate. The integrated evaluation of data routinely available from diagnostic work-up allows accurate prediction of the outcome; functional and angiographic data provide incremental prognostic information over clinical and ECG variables.

Abstract
5-Fluorouracil, a widely used drug in cancer treatment, is known to have cardiotoxic effects: chest pain with ECG changes, arrhythmias, arterial hypertension or hypotension, myocardial infarction, cardiogenic shock and sudden death have been described in the literature. Coronary artery vasospasm is the pathogenetic mechanism hypothesized in most cases, but mechanisms other than myocardial ischemia had been advocated in some patients. The approach to the patient with persistent chest pain, despite therapy and persistent ST-segment elevation mimicking an acute myocardial infarction, has not been well addressed, and the appropriate diagnostic and therapeutic pathways have not yet been defined. We present our experience regarding 2 patients treated with 5-fluorouracil and referred to our coronary care unit because of prolonged chest pain (in one case with clinical evidence of hemodynamic impairment) and persistent ST-segment elevation, in whom an acute myocardial infarction was suspected. One patient was treated with systemic fibrinolysis, and coronary angiography was performed 6 days later; the other was submitted to urgent coronary angiography shortly after admission. In both cases the ECG and echocardiographic abnormalities were transient and normalized within a few days, the serum markers of myocardial necrosis were persistently in the normal range and the coronary artery trees were normal. The diagnostic and therapeutic approach to patients with this unusual clinical presentation is also discussed.

Abstract
The aim of this study was to assess the safety and prognostic value of dipyridamole 201T1 imaging very early after acute myocardial infarction in patients treated with thrombolytic therapy. Fifty-two consecutive patients with an uncomplicated clinical course underwent quantitative planar dipyridamole 201T1 imaging 2 5 days after acute myocardial infarction. The patients were followed for 14 +/- 7 months after discharge. No major complications occurred during the test. Of the 30 patients with redistribution, five (16.6%) developed in-hospital unstable angina as against none of the 22 patients without redistribution. During follow-up, a total of live late cardiac events were observed: two deaths and two cases of unstable angina in the group with reversible defects and one reinfarction in the group with fixed defects. The 1-year actuarial probability of being free of cardiac events was, respectively, 66 +/- 10% and 94 +/- 5% in the patients with and without redistribution (P < 0.01). In conclusion, in patients treated with thrombolysis, dipyridamole-201T1 imaging very early after uncomplicated acute myocardial infarction is a feasible and safe test. Patients with fixed defects appear to be at low risk and may be candidates for early discharge; the presence of redistribution identifies a subgroup of patients who may benefit from further careful clinical evaluation.

Abstract
BACKGROUNDS During the course of acute myocardial infarction (AMI), the appearance of signs of left ventricular failure (LVF) (cardiogenic shock, acute pulmonary edema, congestive heart failure) is a prognostically negative event which is still relatively frequent even in patients receiving fibrinolytic therapy. The early identification of patients exposed to such a risk would allow adequate diagnostic and therapeutic preventive measures to be taken. AIM To evaluate, in a population of AMI patients undergoing thrombolysis and without any serious complications at the moment of hospitalisation, which anamnestic, clinical and instrumental data obtained within the first 24 hours best identify those who will subsequently develop full-blown LVF. Secondary aim is to evaluate the role that extension of coronary disease plays in determining the occurrence of LVF. METHODS The study involved 104 consecutive patients aged < 75 years admitted to hospital for AMI with ST-segment elevation, within 12 hours of the onset of symptoms, in Killip class 1-2 upon entry to the CCU, and treated with thrombolytic therapy. The study design included the collection of anamnestic and clinical data upon admission to the CCU; an enzymatic curve during the first 4 days; the ECG at entry, and 4 and 24 hours after the beginning of fibrinolysis; the chest X-ray, the 2D-echocardiography (2D-echo) and the hemodynamic measurements within the first 24 hours; a coronary angiography on the tenth day (or earlier if clinically necessary). RESULTS Seventeen patients (16%) presented signs of LVF; 8 (7.6%) with cardiogenic shock, 9 with congestive heart failure: 3 died (3%), all for shock. Univariate analysis correlated LVF with: 1) the indices of the extension of ischemic/necrotic damage: number of derivations with ST elevation (p < 0.04) and Q waves (p < 0.05) at first ECG, maximum peak of myocardial enzyme (p < 0.02), wall motion score index (p < 0.001), percentage extension of asynergy (p < 0.001), presence of remote asynergy (p < 0.001), left ventricular (LV) end-systolic (p < 0.001) and end-diastolic volume (p < 0.01), and LV ejection fraction (EF) (p < 0.001) at 2D-echo; 2) the indices of hemodynamic involvement: Killip class 2 at entry (p < 0.02), pulmonary venous flow diversion at chest X-ray (p < 0.001), systolic (p < 0.05), diastolic (p < 0.01) and mean (p < 0.01) pulmonary pressure, capillary wedge pressure (p < 0.01), and the LV systolic work index (p < 0.05). Multivariate analysis showed that the only independent variable predictive of LVF was the EF at 2D-echo (p < 0.001): the sensitivity and specificity of EF was respectively 36% and 97% at cut-off value of 0.30, and 93% and 69% at cut-off value of 0.45. Multivessel coronary disease was found more frequently in patients who developed LVF (p < 0.05) and was correlated with 2D-echo LV involvement: presence of remote asynergies (p < 0.0001), lower EF (p < 0.01), higher wall motion score index (p < 0.001) and percentage extension of asynergy (p < 0.01). CONCLUSIONS The incidence of LVF in patients with AMI, without serious complications at onset, is still relatively high (16%) even if they are treated with thrombolysis. Of all evaluated clinical and instrumental indices, multivariate analysis showed that EF at 2D-echo was the only independent variable predictive of LVF. Extension of coronary disease correlated with development of LVF. Moreover, worse LV performance and greater regional contractility involvement at 2D-echo correlated with extension of coronary disease. Consequently, echocardiography would appear to be bed-side, simple, reliable and accurate mean of establishing a prognosis from the moment a patient with AMI is admitted to a CCU.

Abstract
We performed continuous echocardiographic examination during the i.v. administration of rtPA in three patients with recent-onset, mobile right atrial thrombosis, in order to assess both the timing and mode of thrombus resolution. In all these cases, right atrial thrombus disappeared before the scheduled dose (100 mg i.v. within three hours) was completed: 60 mg of rtPA were required in the first patient, and 50 mg in the other two. In the first case, the thrombus divided into numerous smaller fragments chaotically moving in the right chambers before disappearing; in the second, the echo reflectivity of the thrombus gradually diminished and the mass showed multiple echo-lucent cavities before disappearing; in last case, the atrial mass migrated from the right atrium to the right ventricle before disappearing. None of the patients experienced any symptoms at the dissolving of the thrombus; bleeding complications occurred in all three (in one, at the site of previous PTCA; in another, at the site of arterial and venous puncture; in the third the haematoma was localized at the site of a previous orthopedic operation) but only two required blood transfusion. In patients with right atrial thrombosis, continuous echocardiographic examination allows us to identify both the timing and mode of thrombus resolution, and the occurrence of new-onset peripheral pulmonary embolization. This information can help in optimizing the dosage of the drug in patients in whom bleeding complications can be suspected to occur after thrombolytic therapy.

Abstract
In order to evaluate the evolution (progression and regression) of coronary atherosclerosis, 61 patients (8 with stable angina, 9 with unstable angina, 15 with a recent myocardial infarction, 29 with multivessel coronary artery disease and treated with successful one-vessel angioplasty) were enrolled in a prospective study. In the angioplasty group, only untreated vessels were considered for the analysis. All patients underwent coronary angiography before hospital discharge and after one year, in accordance with the study protocol. In 13 patients (21%) a repeat angiography was performed at 6.3 +/- 2.7 months for clinical reasons (myocardial infarction, changing pattern angina, angina recurrence). All patients were asymptomatic or mildly symptomatic on medical therapy between the angiographic studies. Progression (decrease in internal luminal diameter at the site of stenosis greater than or equal to 20%; new onset of lesions, new episodes of total occlusions) was found in 16 out of 216 stenoses (7%) and in 14 out of 61 patients (23%). Regression (increase greater than or equal to 20% in internal luminal diameter; reopening of a previously occluded vessel) was found in 11 out of 227 lesions (5%) and in 7 out 61 patients (11%). At repeat angiography, the increase in severity was found more frequently in stenoses greater than 5 mm in length and with a reduction of greater than or equal to 75% in luminal diameter. Regression was more frequent in the occluded vessel supplying a recently infarcted area. No significant relationship was observed between lesion morphology (concentric, eccentric, with plaque ulceration, thrombi, border irregularities) and progression or regression. Lesions with plaque ulceration (with or without superimposed thrombi) were found only in patients submitted to coronary angiography close to an acute ischemic attack. Morphologic regression (disappearance of ulceration, border irregularities, thrombi) was also observed, without any significant changes occurring in the severity of the underlying stenosis. Progression may occur independently of worsening in the clinical status; on the contrary, regression was only found in patients without new cardiac events. Nevertheless, clinical status does not seem to be closely correlated to progression, regression, or changes in plaque morphology.
