Abstract
AIMS The current European Society of Cardiology (ESC) guidelines provide clear indications for the treatment of acute and chronic heart failure (HF). Nevertheless, there is a constant need for real-world evidence regarding the effectiveness, adherence, and persistence of drug therapy. We investigated the use of sacubitril/valsartan for the treatment of HF with reduced ejection fraction in real-world clinical practice in Italy. METHODS AND RESULTS An observational, retrospective, non-interventional cohort study based on electronic medical records from nine specialized hospital HF centres in Italy was carried out on patients with prescription of sacubitril/valsartan. Overall, 948 patients had a prescription of sacubitril/valsartan, with 924 characterized over 6 months and followed up for 12 months. Pharmacoutilization data at 1 year of follow-up were available for 225 patients {mean age 69.7 years [standard deviation (SD) = 10.8], 81.8% male}. Of those, 398 (45.2%) reached the target dose of sacubitril/valsartan of 97/103 mg in a mean time of 6.9 (SD = 6.2) weeks. Blood pressure and hypotension in 61 patients (65%) and worsening of chronic kidney disease in 10 patients (10.6%) were the main reasons for not reaching the target dose. Approximatively 50% of patients had a change in sacubitril/valsartan dose during follow-up, and 158 (70.2%) were persistent with the treatment during the last 3 months of follow-up. A sensitivity analysis (persistence during the last 4 months of follow-up) showed persistence for 162 patients (72.0%). Adherence data, available for 387 patients, showed full adherence for 205 (53%). Discontinuation (102/717 patients, 14.2%) was mainly due to hypotension and occurred after a mean time of 34.3 (SD = 28.7) weeks. During follow-up, out of 606 patients with available data, 434 patients (71.6%) had an HF add-on drug or drugs concomitant with sacubitril/valsartan. HF-related hospitalization during follow-up was numerically higher in non-persistent (16/67 patients, 23.9%) vs. patients persistent to sacubitril/valsartan (30/158, 19%) (P = 0.405). CONCLUSIONS Real-world data on the use of sacubitril/valsartan in clinical practice in Italy show a rapid titration to the target dose, high therapeutic adherence enabling a good level of therapeutic management in line with ESC guidelines for patients with reduced ejection fraction.

Abstract
Sacubitril/valsartan reduces heart failure (HF)-related hospitalizations and cardiovascular mortality in PARADIGM-HF and has become a foundational treatment for HF with reduced ejection fraction (HFrEF). However, data of its routine real-world use are limited, and evidence from Italian settings is lacking. The REAL.IT study aimed to characterize the demographics, pharmacotherapy, clinical characteristics and outcomes of sacubitril/valsartan-treated Italian patients with HFrEF. Electronic medical records of patients initiating sacubitril/valsartan from October 2016 to June 2019 at nine specialized hospital outpatient HF centers across Italy were reviewed. Overall, 924 adults (mean age 64.5 years, 84.6% male) were included. At baseline, 38.7% had an ischemic HF etiology, 45.9% hypertension, 23.2% atrial fibrillation, 25.4% diabetes mellitus, 26.1% an implantable cardioverter-defibrillator and 31.9% coronary artery bypass grafting. There were no clear patterns of patient selection over time. During follow-up, NYHA class improved in 37.5% of patients after a mean of 5.3 ± 3.8 months; 36.1% and 16.7% of patients were in NYHA class III during characterization and after one year of follow-up, respectively. Left ventricular ejection fraction (LVEF) improved ≥5% in 56.3% of patients at one year; 39.7% had ≥30% reduction of N-terminal pro-B-type natriuretic peptide; 2.2% had hyperkalemia during characterization and 2.6% during follow-up; and 3.8% had hypotension during characterization and 12% during follow-up. A total of 50 (5.8%) of patients had device implantation (ICD/CRT) during follow-up. HF-related hospitalization was recorded in 19.6% of patients during follow-up; 3.8% of patients died, approximately 1.3% from cardiovascular causes. Our real-world data confirm the favorable effectiveness and tolerability of sacubitril/valsartan observed in pivotal randomized controlled trials.

Abstract
Abstract
Aims
The aim of this multicentre registry was to verify the association between an exaggerated blood pressure response (EBPR) to exercise stress test (EST) and evidence of previous myocardial and/or brain ischaemic events in the general population.
Methods and results
All subjects who underwent EST for screening of ischaemic heart disease and/or follow-up and re-evaluation of heart disease were included in the registry. Patients who discontinued EST due to early muscle exhaustion, younger individuals (<18 years), patients with potentially dangerous channelopathies or ventricular arrhythmias, as well as those with disabling chronic diseases or experiencing cardiovascular events in the 3 months prior to TE. Everyone performed EST on a treadmill or cycle ergometer using similar protocols in the various centres. Based on some study in the literature, we identified the EBPR to exercise for a systolic BP rise >60 mmHg (men) or > 50 mmHg (women) compared to pre-exercise baseline measurement, but also an absolute value >210 or > 190 mmHg, respectively. Retrospectively, we verified the presence of non-disabling ischaemic cardiac and cerebrovascular events over the past 10 years. Five hundred and three subjects of mean age 61 ± 11 years were included in the registry. EST was performed on a treadmill in 65% of subjects and maximal workload was achieved by 75% of them. Subjects with EBPR were 170 (34%) vs. 333 (66%) who had normal response (controls). EBPR group included most male subjects, often overweight and with a higher prevalence of diabetes (31% vs. 20% in the control group, P < 0.01), and with already diagnosed arterial hypertension in a half of cases. Previous ischaemic myocardial events were found in 35% of EBPR subjects vs. 36% of controls (P = NS), while cerebrovascular disease in 20% vs. 10%, respectively (P < 0.005).
Conclusion
Albeit retrospectively performed, this multicentre registry highlighted an association between EBPR to exercise (present in more than one-third of the subjects examined, especially males) and history of cerebrovascular ischaemic events within 10 years prior to enrolment. In line with previous studies, present data confirmed a clinical impact of EBPR on exercise. However, the precise pathophysiological mechanism(s) need to be clarified yet, also in terms of therapies against such exaggerated functional response and its possible prognostic impact over time.

Abstract
Background: atherosclerotic process inexorably advances in patients reaching low-density lipoprotein cholesterol (LDL-C) targets. An attractive hypothesis is that lipoprotein particles (very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL)), could contribute to residual risk. The present study aims to investigate the relationship between carotid intima-media thickness (IMT) and different lipoprotein subfractions in a cohort of healthy postmenopausal women. Methods: 75 postmenopausal women, at LDL-C target levels without overt cardiovascular disease, underwent biochemical analyses (including subfraction assay of plasma lipoproteins) and carotid ultrasound examination. Results: a statistically significant correlation between VLDL and carotid IMT (p < 0.001) was found. No significant correlation was found between carotid IMT and LDL-C (p = 0.179), IDL-C (p = 0.815), high-density lipoprotein (HDL) (p = 0.855), and LDL score (p = 0.240). Moreover, IMT is significantly correlated to LDL particle diameter (p = 0.044). After adjusting for age, systolic blood pressure, body mass index, smoking habits, glucose plasma concentration, and Lipoprotein(a) (Lpa) levels, multivariate analysis showed that women in the third tertile of VLDL-C, compared with those in the first tertile, were significantly associated to the highest IMT (p = 0.04). Conclusions: in this cohort of postmenopausal women, VLDL-C was significantly associated to carotid IMT, independent of main cardiovascular risk factors. These findings pave the way for targeting circulating concentrations of VLDL-C to reduce cardiovascular events in patients with target LDL-C levels.

Abstract
BACKGROUND Sacubitril/valsartan has been shown to be superior to enalapril in reducing the risks of death and hospitalization for heart failure (HF). However, knowledge of the impact on cardiac performance remains limited. We sought to evaluate the effects of sacubitril/valsartan on clinical, biochemical and echocardiographic parameters in patients with heart failure and reduced ejection fraction (HFrEF). METHODS Sacubitril/valsartan was administered to 205 HFrEF patients. RESULTS Among 230 patients (mean age 59 ± 10 years, 46% with ischemic heart disease) 205 (89%) completed the study. After a follow-up of 10.49 (2.93 ± 18.44) months, the percentage of patients in New York Heart Association (NYHA) class III changed from 40% to 17% (p < 0.001). Median N-Type natriuretic peptide (Nt-proBNP) decreased from 1865 ± 2318 to 1514 ± 2205 pg/mL, (p = 0.01). Furosemide dose reduced from 131.3 ± 154.5 to 120 ± 142.5 (p = 0.047). Ejection fraction (from 27± 5.9% to 30 ± 7.7% (p < 0.001) and E/A ratio (from 1.67 ± 1.21 to 1.42 ± 1.12 (p = 0.002)) improved. Moderate to severe mitral regurgitation (from 30.1% to 17.4%; p = 0.002) and tricuspid velocity decreased from 2.8 ± 0.55 m/sec to 2.64 ± 0.59 m/sec (p < 0.014). CONCLUSIONS Sacubitril/valsartan induce "hemodynamic recovery" and, consistently with reduction in Nt-proBNP concentrations, improve NYHA class despite diuretic dose reduction.

Abstract
Patients with microvascular angina (MVA) often have persistence of symptoms despite full classical anti-ischemic therapy. In this study, we assessed the effect of ivabradine and ranolazine in MVA patients. We randomized 46 patients with stable MVA (effort angina, positive exercise stress test [EST], normal coronary angiography, coronary flow reserve <2.5), who had symptoms inadequately controlled by standard anti-ischemic therapy, to ivabradine (5 mg twice daily), ranolazine (375 mg twice daily), or placebo for 4 weeks. The Seattle Angina Questionnaire (SAQ), EuroQoL scale, and EST were assessed at baseline and after treatment. Coronary microvascular dilation in response to adenosine and to cold pressor test and peripheral endothelial function (by flow-mediated dilation) were also assessed. Both drugs improved SAQ items and EuroQoL scale compared with placebo (p <0.01 for all), with ranolazine showing some more significant effects compared with ivabradine, on some SAQ items and EuroQoL scale (p <0.05). Time to 1-mm ST-segment depression and EST duration were improved by ranolazine compared with placebo. No effects on coronary microvascular function and on flow-mediated dilation were observed with drugs or placebo. In conclusion, ranolazine and ivabradine may have a therapeutic role in MVA patients with inadequate control of symptoms in combination with usual anti-ischemic therapy.

Abstract
OBJECTIVE To assess whether reduction of heart rate (HR) has beneficial effects on endothelial function in patients with type 2 diabetes mellitus (T2DM). DESIGN Randomised, double-blind, placebo-controlled study. SETTING University hospital. PATIENTS 66 T2DM patients without overt cardiovascular disease. INTERVENTIONS Patients were randomised to receive for 4 weeks, in addition to their standard therapy, one of the following treatments: atenolol (25 mg twice daily), ivabradine (5 mg twice daily) or placebo (1 tablet twice daily). MAIN OUTCOME MEASURES Systemic endothelial function, assessed by flow-mediated dilation (FMD); endothelium-independent vasodilation, assessed by nitrate-mediated dilation (NMD); cardiac autonomic function, assessed by HR variability (HRV). RESULTS 61 patients completed the study (19, 22 and 20 patients in atenolol, ivabradine and placebo groups, respectively). Compared with baseline, HR was similarly reduced by atenolol (87±13 vs 69±9 bpm) and ivabradine (86±12 to 71±9 bpm), but not by placebo (82±10 vs 81±9 bpm) (p<0.001). FMD improved at follow-up in the atenolol group (4.8±1.7 vs 6.4±1.9%), but not in the ivabradine group (5.2±2.5 vs 4.9±2.2%) and in the placebo group (4.8±1.5 vs 4.7±1.7%) (p<0.01). NMD did not change significantly in any group. HRV parameters did not change in the placebo group; they, instead, consistently increased in the atenolol, whereas a mild increase in SDNNi was only observed in the ivabradine group. A significant correlation was found in the atenolol group between HR and FMD changes (r=-0.48; p=0.04). CONCLUSIONS Despite a comparable reduction in HR, atenolol, but not ivabradine, improved FMD in T2DM patients suggesting that changes in HR are by themselves unlikely to significantly improve endothelial function.

Abstract
Background: Cardiopulmonary exercise testing with ventilatory expired gas analysis (CPET) has proven to be a valuable tool for assessing patients with chronic heart failure (CHF). The maximal oxygen uptake (peak V02) is used in risk stratification of patients with CHF. The minute ventilation-carbon dioxide production relationship (VE/VCO2 slope) has recently demonstrated prognostic significance in patients with CHF. Methods: Between January 2006 and December 2007 we performed CPET in 184 pts (146 M, 38 F, mean age 59.8 ± 12.9 years), with stable CHF (96 coronary artery disease, 88 dilated cardiomyopathy), in NYHA functional class II (n.107) - III (n.77), with left ventricular ejection fraction (LVEF) ≤ 45%,. The ability of peak VO2 and VE/VCO2 slope to predict cardiac related mortality and cardiac related hospitalization within 12 months after evaluation was examined. Results: Peak VO2 and VE/VCO2 slope were demonstrated with univariate Cox regression analysis both to be significant predictor of cardiac-related mortality and hospitalization (p < 0.0001, respectively). Non survivors had a lower peak VO2 (10.49 ± 1.70 ml/kg/min vs. 14.41 ± 3.02 ml/kg/min, p < 0.0001), and steeper Ve/VCO2 slope (41.80 ± 8.07 vs. 29.84 ± 6.47, p < 0.0001) than survivors. Multivariate survival analysis revealed that VE/VCO2 slope added additional value to VO2 peak as an independent prognostic factor (χ2: 56.48, relative risk: 1.08, 95% CI: 1.03 – 1.13, p = 0.001). The results from Kaplan-Meier analysis revealed a 1-year cardiac-related mortality of 75% in patients with VE/VCO2 slope ≥ 35.6 and 25% in those with VE/VCO2 slope < 35.6 (log rank χ2: 67.03, p < 0.0001) and 66% in patients with peak VO2 ≤ 12.2 ml/kg/min and 34% in those with peak VO2 > 12.2 ml/kg/min (log rank χ2: 50.98, p < 0.0001). One-year cardiac-related hospitalization was 77% in patients with VE/VCO2 slope ≥ 32.5 and 23% in those with VE/VCO2 slope < 32.5 (log rank χ2: 133.80, p < 0.0001) and 63% in patients with peak VO2 ≤ 12.3 ml/kg/min and 37% in those with peak VO2 > 12.3 ml/kg/min (log rank χ2: 72.86, p < 0.0001). The VE/VCO2 slope was demonstrated with receiver operating characteristic curve analysis to be equivalent to peak VO2 in predicting cardiac-related mortality (0.89 vs. 0.89). Although area under the receiver operating characteristic curve for the VE/VCO2 slope was greater than peak VO2 in predicting cardiac-related hospitalization (0.88 vs 0.82), the difference was no statistically significant (p = 0.13). Conclusion: These results add to the present body of knowledge supporting the use of CPET in CHF patients. The VE/VCO2 slope, as an index of ventilatory response to exercise, is an excellent prognostic parameter and improves the risk stratification of CHF patients. It is easier to obtain than parameters of maximal exercise capacity and is of equivalent prognostic importance than peak VO2.

Abstract
BACKGROUND Exercise causes enhanced sympathetic discharge and results in physiologic tachycardia. However, in some patients with a diseased conduction system resulting from acute ischemia, exercise can precipitate heart block. METHODS AND RESULTS In this report we describe a 51 years old male patient with transient advanced degree atrioventricular (AV) block developed during recovery from exercise stress testing, resolved after the administration of atropine. Nuclear perfusion imaging demostrated stress-induced ischemia of the inferior-apical segments, and recovery of perfusion in the images obtained at rest. Coronarography showed critical stenosis of the right coronary artery, which was treated by percutaneous coronary intervention (PCI) and drug eluting stent (DES) deployment. CONCLUSION Nuclear myocardial perfusion imaging provides noninvasive evidence that transient ischemia of the infero-apical segment can result in advanced degree AV block in patient with critical severe right coronary disease.

Abstract
AIM N-terminal pro-b-type natriuretic peptide (NT pro-BNP) is a neurohormone synthesized predominantly in ventricular myocardium. In patients with symptoms of heart failure, elevation in NT pro-BNP accurately identifies ventricular dysfunction. However, NT pro-BNP levels are not specific for ventricular dysfunction in patients who do not have overt symptoms of heart failure, suggesting that other cardiac processes such as myocardial ischemia may also cause elevation in NT pro-BNP. The study was aimed to determine whether NT pro-BNP elevations are associated with myocardial ischemia. METHODS One hundred and thirty patients (104 males, 26 females, mean age 61+12 years), with ST elevation acute myocardial infarction (STEMI) and preserved left ventricular ejection fraction (>45%) at echocardiography performed at entry, from February 2003 and February 2004 were enrolled. In all patients NT pro-BNP plasma levels were checked at entry and 4-5 days after symptoms onset. In addition, maximal or symptom-limited exercise treadmill test (Bruce protocol), and myocardial perfusion scintigraphy using [(99m)Tc]Tetrofosmin single photon emission computed tomography (SPECT) imaging were performed within 30 days of STEMI. Ischemia was defined as reversible perfusion abnormalities. RESULTS Of the 130 participants, 66 (51%) had inducible ischemia. Compared with patients in the lowest tertile, those in the highest tertile of NT pro-BNP had a greater significant risk of residual ischemia (odds ratio: 8.66; 95% CI, 3.90 to 19.24). Nevertheless patients in the highest tertile were older (64.19+/-10.80 years versus 55.90+/-9.67 years, P = 0.0001), had a lower left ventricular ejection fraction (49.70+13.46% versus 59.49+/-6.58%, P = 0.0001) and had a great rate of acute myocardial infarction (anterior acute myocardial infarction = 40.63% versus 25%). CONCLUSIONS Elevated levels of NT pro-BNP are associated with residual myocardial ischemia among patients with STEMI and preserved left ventricular ejection fraction, as demonstrated by perfusion defect on SPECT imaging, suggesting that these patients may need further evaluation for stratification of the future risk of fatal events. The observed association between NT pro-BNP levels and ischemia may explain because tests for NT pro-BNP are not specific for ventricular dysfunction among patients with coronary artery disease.

Abstract
BACKGROUND Decreased exercise capacity is the main factor restricting the daily life of patients with chronic heart failure. N-terminal pro-brain natriuretic peptide (NT pro-BNP) is strongly related to the severity of and is an independent predictor of outcome in chronic heart failure. DESIGN The study aimed to evaluate the effect of exercise training on functional capacity and on changes in NT pro-BNP levels and to assess the effect of exercise training on quality of life. MATERIALS AND METHODS Sixty patients (45 men/15 women, mean age 52.7 years; +/-5.3 SD), with stable heart failure (45 ischaemic/hypertensive and 15 idiopathic patients), in New York Heart Association (NYHA) functional class II (n=35) to III (n=25), with an ejection fraction less than 40%, were randomly assigned to a training (n=30) and a control group (n=30). The training group (30 patients) performed 3 months of supervised physical training programme using a bicycle ergometer for 30 min three times a week at a load corresponding to 60-70% of their oxygen consumption (VO2) peak. The control group did not change their previous physical activity. A graded maximal exercise test with respiratory gas analysis and an endurance test with constant workload corresponding to 85% of the peak oxygen load at the baseline and after 3 months were performed, and at the same times NT pro-BNP levels were measured. RESULTS The exercise capacity increased from 15.8 (+/-2.3 SD) to 29.9 (+/-2.1 SD) min (P<0.0001) and the peak VO2 tended to improve from 14.5 (+/-1.4 SD) to 17.7 (+/-2.6 SD) ml/kg per min (P<0.0001) during the supervised training period. VO2 at the anaerobic threshold increased from 12.9 (+/-1.0 SD) to 15.5 (+/-1.7 SD) ml/kg per min (P<0.0001). NT pro-BNP levels decreased from 3376 (+/-3133 SD) to 1434 (+/-1673 SD) pg/ml (P=0.043). The positive training effects were associated with an improvement in the NYHA functional class. CONCLUSION Physical training of moderate intensity significantly improves the exercise capacity and neurohormonal modulation in patients with chronic heart failure. This is associated with an alleviation of symptoms and improvement in quality of life.

Abstract
BACKGROUND Failure to reach 80% of maximal predicted heart rate (HR) during exercise may render a myocardial perfusion single photon emission computed tomography (SPECT) study non-diagnostic for ischemia detection. We sought to investigate the injection of atropine in patients who fail to achieve 80% of age-predicted HR during exercise performed for myocardial perfusion SPECT (MPS), defining its safety and efficacy to raise HR to adequate levels as well as its effect on MPS interpretation. METHODS AND RESULTS Between January 2002 and December 2004, we studied 3,150 consecutive patients (2,253 men and 897 women, mean age 55 +/- 6 years) who were referred to a single office-based nuclear cardiology laboratory for MPS using SPECT imaging. One milligram of atropine was administered to patients that were unable to continue because of fatigue before reaching minimal HR, without an ischemic response (group A, n = 397). The scintigraphic results for group A were compared with those of patients who spontaneously achieved target HR (group B, n = 2,753). In group A, mean HR before atropine injection was 119.5 +/- 13.6 beats per minute (bpm), and it increased up to 137.3 +/- 13.5 bpm after drug administration, with an incremental of 17.8 +/- 6.9 bpm (P < 0.0001). The mean percentage of age-related HR achieved in this group was 83.5 +/- 8.1%. In 302 of this patients (76.1%) more than 80% of their aged-related HR (86.9 +/- 5.1%) was attained. No major adverse effects occurred. When groups A and B were compared, baseline and peak HR, rate pressure product, and maximal metabolic equivalents achieved were higher in group B. There were no significant differences in the percentage of total positive perfusion studies between both groups: 210/397 patients (52.9%) in group A and 1,342/2,753 patients (48.7%) in group B (P = 0.39). Ischemia or ischemia plus scar was found in 112/397 patients (28.2%) in group A and in 923/2,753 patients (33.5%) of group B (P = 0.14). CONCLUSION Atropine added to exercise stress testing in patients who cannot achieve their 80% age-related HR is a safe, well-tolerated, and feasible method for MPS.

Abstract
BACKGROUND Non-invasive positive pressure ventilation (NIPPV) is an effective treatment for acute respiratory failure in patients with chronic obstructive pulmonary disease. We assessed the efficacy and safety of this therapy in acute cardiogenic pulmonary edema (ACPE). METHODS In addition to routine therapy consisting of oxygen, nitrates and diuretics, 60 patients (39 male, 21 female, mean age 72.5 +/- 15.8 years) were started on full mask NIPPV using a Sullivan VPAP II ventilator delivering pressure support 15 cm H2O, PEEP 5 cm H2O, FiO2 100%. Pressure support were titrated to achieve oxygen saturation (SaO2) > 95%. Physiological measurements were obtained in the first 2 h and at 3 h, 4 h, and 10 h. Outcome measures included arterial blood gas (ABG), Borg dyspnea score, vital signs, and need for endotracheal intubation (ETI). RESULTS Initial mean values on FiO2 100% by non nonrebreather mask: pH 7.11 +/- 0.25, paCO2 67.7 +/- 17.5 mmHg, paO2 71.5 +/- 29.7 mmHg, SaO2 83 +/- 12%, lactate concentrations 4.7 +/- 2.3 mmol/L, Borg score 8.6 +/- 1.3, respiratory rate (RR) 41 +/- 7. At 60 minutes of NIPPV, improvement was statistically significant: pH 7.35 +/- 0.18 (difference 0.24; p < 0.0001), paCO2 43 +/- 13 mmHg (difference 24.7; p < 0.0001), paO2 102 +/- 10 mmHg (difference 30.5; p < 0.0001), SaO2 99 +/- 5% (difference 16; p < 0.0001), lactate concentrations 1.2 +/- 0.8 (difference 3.5; p < 0.0001) Borg score 3.6 +/- 0.9 (difference 5; p < 0.0001), RR 24.6 +/- 5 (difference 17.1; p < 0.0001). NIPPV duration ranged from 40 minutes to 24 hours (median 3 hours, 30 minutes). Fifty-six patients (93.4%) improved allowing cessation of NIPPV. ETI was required in four (6.6%) of 60 patients. There were non complications of NIPPV. CONCLUSION In this study of acute cardiogenic pulmonary edema, NIPPV is an effective treatment and may help prevent ETI.

Abstract
BACKGROUND ST segment depression (STD) is a standard electrocardiographic sign of myocardial ischemia. Although STD may represent reciprocal changes in patients with previous myocardial infarction, studies of reciprocal changes during exercise testing are scarce. METHODS From December 1999 to December 2000, 160 patients (119 males, 41 females, mean age 54 +/- 8 years), undergoing, maximal or symptom-limited exercise treadmill test (Bruce-protocol), myocardial perfusion scintigraphy using technetium-99m tetrofosmin single photon emission computed tomography (SPECT) imaging, within 30 days of an uncomplicated inferior Q wave myocardial infarction. The location of STD at the electrocardiogram (ECG) was defined as anterior (V1-4), high lateral (I, aVL), and lateral (V5-6). Ischemia was defined as reversible perfusion abnormalities. RESULTS STD occurred in anterior leads in 29 patients (18.1%), in the lateral leads in 41 patients (25.6%), in the high lateral leads in 20 patients (12.5%). In 70 patients (43.8%) no significant STD occurred during the exercise test. ST segment elevation occurred in 28 patients (17.5%) in inferior leads. High lateral STD was associated with inferior ST elevation in 16 patients (80%), whereas only eight patients (19.5%) with lateral STD and nine patients (31%) with anterior STD were associated with inferior ST elevation. Ischemia was detected in 63 of 90 patients (70%) with and in 10 of 70 patients (14.3%) without STD (p < 0.0001). Patients with high lateral STD had a higher prevalence of fixed perfusion defects in the inferior wall (95 vs. 27.8%) and in posterolateral wall (75 vs. 18.9%) compared with other patients (p = 0.003 and 0.002, respectively). Ischemia was more prevalent in patients with lateral STD than without (87.8 vs. 14.3%, p < 0.0001). CONCLUSION In patients with inferior Q wave, the presence of exercise-induced STD in lateral and anterior leads appears to be a sign of myocardial ischemia, and may require invasive evaluation; on the other hand, the presence of STD in high lateral leads should be recognized as a reciprocal change for ST elevation in the inferior leads, and may not be an indication for invasive evaluation.

Abstract
BACKGROUND The aim of this study was to evaluate the effectiveness of glycoprotein (GP) IIb/IIIa receptor inhibitors in acute myocardial infarction (AMI) patients in case of unsuccessful and failed thrombolysis. METHODS Eighty-four patients hospitalized within 4 hours of symptom onset were randomized (single blind) into two groups. Regardless of the group, placebo or GP IIb/IIIa inhibitors were administered to patients who did not present with reperfusion signs (failed thrombolysis) 30 min after starting thrombolysis and 30-60 min after the end of full thrombolysis in patients with pain recurrence and ST-segment elevation (unsuccessful thrombolysis). Reperfusion was assessed by the creatine kinase peak occurring within 12 hours, by the observation of rapid ST-segment reduction (50-70% within 1 hour) in the 12-lead ECG continuous tracing, by the rapid regression of pain and by the development of early ventricular arrhythmias. Group 1 patients (n = 42) received, during failed thrombolysis or after 30-60 min of effective thrombolysis but with pain recurrence and ST-segment elevation (unsuccessful thrombolysis), treatment with i.v. GP IIb/IIIa inhibitors, heparin according to the TIMI 14 trial, and aspirin. Group 2 patients (n = 42) received a full dose of recombinant tissue-type plasminogen activator (rt-PA 100 mg) and placebo either during failed thrombolysis or, after 30 min of effective thrombolysis but with pain recurrence and ST-segment elevation, and standard heparin treatment and aspirin. RESULTS In group 1, 39 patients showed rapid reperfusion (4 +/- 3 min); 22 patients received rt-PA 65 mg and 20 patients received rt-PA 100 mg and subsequent GP IIb/IIIa inhibitor treatment. Coronary angiography, performed after 12-72 hours showed patency of the infarct-related artery in 39 patients whose clinical picture was suggestive of rapid reperfusion during administration of a bolus of GP IIb/IIIa inhibitors. In group 2, no patients showed reperfusion and they were submitted to rescue coronary angioplasty (p < 0.05). Side effects occurred in 3 cases in group 1 and in 2 cases in group 2. Patients receiving GP IIb/IIIa inhibitors showed a reduced incidence of stent treatment (p = NS) and a significant reduction in the occurrence of events (angina) within 30 days of treatment (p = NS). CONCLUSIONS Our data suggest that in patients with AMI and failed thrombolysis, treatment with GP IIb/IIIa receptor inhibitors is feasible. The increase in the risk of bleeding was acceptable. The most important result was that this combination is safe.

Abstract
BACKGROUND The goal of therapy in acute myocardial infarction (AMI) is the complete and timely restoration of coronary blood flow. Platelets have a pivotal role in the pathophysiology of AMI. The study was aimed at evaluating the safety and efficacy of the combination of 50 mg alteplase plus tirofiban vs 100 mg alteplase in AMI patients. METHODS One hundred twenty patients (83 males, 37 females; mean age 54.3 +/- 8 years) were hospitalized for suspected AMI within 6 hours of the onset of symptoms. All patients presented pain and persistent ST-segment elevation, were suitable candidates for thrombolysis (1st episode) and were randomized (double blind) into two groups. Group A (n = 60,42 males, 18 females) received 50 mg alteplase (15 mg as bolus, followed by an infusion of 35 mg over 60 min) in combination with tirofiban (0.4 mcg/kg/min for 30 min followed by an infusion of 0.1 mcg/kg/min for 3 days). Group B (n = 60, 41 males, 19 females) received 100 mg of accelerated-dose alteplase alone. Reperfusion criteria were defined as follows: > 50% reduction in the ST-segment elevation; resolution of chest pain; double marker of creatine kinase (CK) and CK-MB activity 2 hours after the start of thrombolysis; reperfusion arrhythmias within the first 120 min of thrombolysis. The blood pressure, heart rate and ECG were continuously monitored. The mortality, re-AMI, recurrent angina, major and minor bleeding, and emergency bypass surgery or coronary angioplasty were checked. RESULTS The groups were similar with regard to clinical data, risk factors, time elapsed from the onset of symptoms to thrombolytic therapy and AMI localization. Forty-seven patients (78.3%) from group A showed reperfusion (15-60 min) vs 25 patients (41.7%) from group B (43-105 min after the end of full-thrombolysis, p = 0.01). Group A patients showed an earlier CK peak and lower CK and CK-MB peaks than those in the control group (p = 0.0001, p = 0.011, p = 0.005, respectively). Nine patients (7.5%) died: 6 (10%) in group B and 3 (5%) in group A (p = NS). A non-fatal re-AMI occurred in 8 patients from group A and in 4 patients from group B (p = NS). Recurrent angina occurred in 27 patients (45%) from group A and in 11 (18.3%) from group B (p = 0.037). Twenty-three of these patients underwent urgent coronary angioplasty (17 from group A and 6 from group B) and 3 from group A and 1 from group B underwent urgent coronary artery bypass grafting (p = NS). The frequency of minor bleeding was higher in group A than in group B (56.7 vs 25%, p = 0.033). No major bleeding was observed in the study groups. At the predischarge echocardiogram, the ejection fraction was higher in group A than in group B (50 +/- 9 vs 44 +/- 7%, p = 0.001). CONCLUSIONS Our data suggest that the combination of glycoprotein IIb/IIIa inhibitors plus alteplase is feasible in AMI patients and that the increased risk of bleeding is an acceptable risk considering the advantage in terms of the reduction in the extent of an AMI. In addition, this combination can allow one to gain time when it is necessary to perform mechanical revascularization in patients admitted to a hospital without an interventional cardiology laboratory or in those who have to be referred to another hospital for urgent coronary artery bypass grafting.

Abstract
BACKGROUND Recent evidence suggests that, via the mineralocorticoid receptors present in cardiovascular tissues, aldosterone exerts profibrotic effects, and that partial aldosterone escape occurs during ACE-inhibitor treatment. METHODS A double-blind, randomized study was performed in order to evaluate the feasibility, tolerability, and the effects of the administration of 25 mg/day of canrenoate plus captopril versus captopril alone to patients with anterior acute myocardial infarction (AMI) unsuitable for or not receiving thrombolytic treatment and to patients in whom such treatment resulted or did not result in reperfusion. One hundred eighty-seven patients with anterior AMI were included in the present study. In all cases serum creatinine concentrations and serum K concentrations were < 2.0 mg/dl and < 5.5 mmol/l respectively. The patients were randomized in two groups: the canrenoate group included 94 patients who received captopril and 25 mg i.v. of canrenoate (1 mg/hour for the first 72 hours and then orally 25 mg/day) whereas the placebo group (93 patients) received captopril and placebo. On admission and on days 10, 90 and 180 all patients underwent echocardiography in order to determine the end-systolic volume (ESV), the ejection fraction (EF), the end-diastolic diameter, the E/A ratio, the E deceleration time as well as the isovolumetric relaxation time (IVRT) and the E and A peak velocities. RESULTS Unreperfused patients did not show patency of the infarct-related artery whereas in reperfused patients this vessel was patent (7-10 days after AMI). The two groups were similar in age, sex, incidence of diabetes, smoking habits, hypertension, creatine kinase enzymatic peak, adjuvant therapy, baseline EF, ESV, and incidence of coronary artery bypass grafting/coronary angioplasty. Following 10 days of treatment (canrenoate group), only 9 patients presented with serum K and creatinine concentrations respectively > 5.5 mmol/l and > 2.0 mg/dl. Among those patients receiving canrenoate, the mitral E/A ratio was higher compared to the placebo group (p = 0.001) whereas the ESV was significantly reduced (p < 0.05). The deceleration time for reperfused patients receiving canrenoate was higher than that observed for reperfused patients in the placebo group. The intragroup EF was significantly increased (p = 0.042). Compared to the placebo group, the IVRT was significantly higher for unreperfused patients receiving canrenoate than in the placebo group (p = 0.001). Serum creatinine, blood urea and K levels as well as the incidence and extent of vessel disease were similar for both groups. No side effects were observed during the study period. CONCLUSIONS Our data suggest that the combination of captopril plus canrenoate is feasible for the initial treatment of patients presenting with AMI. Besides, compared to captopril alone it is more efficacious in improving the E/A ratio, the ESV, the EF, and the IVRT.

Abstract
It is common practice to hospitalize patients with chest pain for a period of observation and to perform further diagnostic evaluation such as exercise treadmill testing (ETT) once acute myocardial infarction (AMI) has been excluded. This study evaluates the safety and efficacy of immediate ETT for patients admitted to the hospital with acute chest pain. One hundred and ninety non-consecutive low-risk patients admitted to the hospital from emergency department with acute chest pain underwent ETT using Bruce protocol immediately on admission to the hospital (median time 165+30 min). Fifty-seven (30%) patients had positive exercise electrocardiograms, 44 (77.2%) of whom had significant coronary narrowing by angiography. An uncomplicated anterior non-Q-wave AMI was diagnosed in one patient. One hundred and eleven (58.4%) patients had negative and 22 (11.6%) patients had non-diagnostic exercise electrocardiograms. Of these 133 patients, 86 (64.7%) were discharged immediately after ETT, 19 (14.3%) were discharged within 24 h, and 28 (21%) were discharged after 24 h of observation. There were no complications from ETT. During the 17+/-6 months follow-up no patients died, and only eight (7.2%) patients with negative ETT experienced a major cardiac event (one AMI and seven angina). In conclusion, our results suggest that immediate ETT of low-risk patients with chest pain who are at sufficient risk to be designated for hospital admission, is effective in further stratifying this group into those who can be safety discharged immediately and those who require hospitalization.

Abstract
Thrombolysis reduces mortality in patients with acute myocardial infarction (AMI) who are hospitalized within 6 hours from the onset of symptoms. AMIs involving a small area of myocardium show a lower mortality in comparison with AMI involving a large area. The present study was aimed at evaluating the safety and efficacy of rescue thrombolysis in patients with large AMI who had failed thrombolysis. Ninety patients (69 Males and 21 Females), mean age 56.7 +/- 9 years, hospitalized for suspected AMI within 4 hours from the onset of symptoms, suitable for thrombolysis (First episode), and showing pain and persistent ST segment elevation 120 minutes after starting thrombolysis, were randomized (double-blind) into two groups. Group A (45 patients: 10 females and 35 males) received an additional thrombolytic treatment (rTPA 50 mg), 10 mg as bolus plus 40 mg in 60 minutes. Group B (45 patients: 11 females and 34 males) received placebo. Positive noninvasive markers were defined as follows: (1) resolution of chest pain, (2) > or = 50% reduction in ST segment elevation, (3) double marker of creatine kinase (CK) and CK-MB activity 2 hours after the start of thrombolysis, and (4) occurrence of reperfusion arrhythmias within the first 120 minutes of thrombolytic therapy. Blood pressure, heart rate, and ECG were continuously monitored. An echocardiogram was carried out at entry, and before discharge, to control ejection fraction and segmentary kinetics. Adverse events such as death, re-AMI, recurrent angina, incidence of major and minor bleeding, and emergency CABG/PTCA were checked. The groups were similar in terms of age, sex, diabetes, smoking habits, hypertension, and adjuvant therapy (beta-blockers). No significant difference was observed between the two groups regarding the time elapsed from the onset of symptoms to thrombolysis and AMI localization. Thirty-five patients (77.7%) showed reperfusion (10-50 minutes) after commencement of additional rTPA. Of the patients receiving placebo, 12 (26.6%) showed reperfusion within 35-85 minutes. Group A showed an earlier and lower CK and CK-MB peak than the control group, (respectively, p = 0.0001-0.009 and 0.002). Mortality (17.7%, 16 patients) was higher in group B than in the additional rTPA group, i.e., 6.6% (3 patients) in group A versus 28.8% (13 patients) in Group B (p = 0.041). Seven patients from group A showed nonfatal re-AMI. Angina was observed in 18 patients (40%) from group A and 3 (6.6%) from group B (p = 0.006). Ten of these patients underwent urgent PTCA (9 from group A and 1 from group B), and 3 from group A underwent urgent CABG. Minor bleeding was higher in group A than in group B (44.4% versus 15.5%, p = 0.047). Major bleeding was observed in group A (nonfatal stroke). At predischarge, the echocardiogram ejection fraction was higher in group A than in group B (46 +/- 8% versus 38 +/- 7%, p = 0.0001). Our data suggest that an additional dose of thrombolytic drug in patients with unsuccessful thrombolysis is feasible and also that the bleeding increase is an acceptable risk in comparison with the advantages obtained in reducing AMI extension. Rescue thrombolysis can allow a gain in time to perform mechanical revascularization in patients admitted to hospital without an interventionist cardiology laboratory or in those who have to be referred to another hospital for urgent CABG.

Abstract
BACKGROUND Thrombolysis reduces mortality in patients with acute myocardial infarction hospitalized within 6 hours of the symptom onset. Infarctions involving a small area of the myocardium show a lower mortality in comparison to those involving a large area. The aim of this study was to evaluate the safety and efficacy of rescue thrombolysis in patients with large acute myocardial infarction who had failed standard thrombolysis. METHODS From January 1995 to December 1997, ninety patients (69 males, 21 females, mean age 56.7 +/- 9 years), hospitalized for suspected acute myocardial infarction within 4 hours of the symptom onset, suitable for thrombolysis (first episode), and who experienced pain and showed persistent ST segment elevation 120 min after starting thrombolysis, were randomized (single blind) into two groups: Group A (n = 45) received an additional thrombolytic treatment (rt-PA 50 mg), 10 mg as a bolus plus 40 mg in 60 min; Group B (n = 45) received conventional therapy. Positive non-invasive markers were defined as follows: resolution of chest pain; > 50% reduction in ST segment elevation; double marker of creatine phosphokinase (CPK) and CK-MB activity 2 hours after the start of thrombolysis; occurrence of reperfusion arrhythmias within the first 120 min of thrombolytic therapy. Blood pressure, heart rate and ECG were continuously monitored. Echocardiogram was carried out at entry and before discharge to control ejection fraction and segmental wall motion. Adverse events such as death, reinfarction, recurrent angina, incidence of major and minor bleeding, and emergency bypass surgery or coronary angioplasty were checked. RESULTS Thirty-five patients (77.7%) showed reperfusion (10-50 min) after the start of additional rt-PA. In patients who did not receive additional thrombolysis, only 12 (26.6%) showed reperfusion 65-115 min after the end of rt-PA infusion. Group A showed an earlier and lower CK and CK-MB peak than Group B (p = 0.0001, p = 0.009, and p = 0.002, respectively). Mortality (n = 16, 17.7%) was higher in Group B (n = 13) than in Group A (n = 3) (28.8 vs 6.6%, p = 0.041). Seven patients from Group A showed non-fatal reinfarction. Angina was observed in 18 (40%) patients from Group A and 3 (6.6%) from Group B (p = 0.006). Ten of these patients underwent urgent coronary angioplasty (9 from Group A and 1 from Group B) and 3 from Group A urgent bypass surgery. Minor bleeding was higher in Group A than in Group B (44.4 vs 15.5%, p = 0.047). A major bleeding was observed in Group A (non-fatal stroke). At predischarge echocardiogram ejection fraction was higher in Group A than in Group B (46 +/- 8 vs 38 +/- 7%, p = 0.0001). CONCLUSIONS Our data suggest that an additional dose of a thrombolytic drug in patients with unsuccessful thrombolysis is feasible, and the bleeding increase is an acceptable risk in comparison with the advantages obtained from a reduced infarct extension. Rescue thrombolysis could save time and allow mechanical revascularization to be carried out in patients admitted to a hospital without interventional cardiology laboratory or in those who have to be refereed to other hospitals for urgent bypass surgery.

Abstract
Two cases of severe intoxication after ingestion of cooked tuna fish were observed. Symptoms and clinical signs were consistent with the scombroid syndrome. Cardiovascular shock was observed in both patients and was associated with subendocardial myocardial infarction in 1 case and acute pulmonary edema with myocardial ischemia in the other. The importance of ECG monitoring in the Intensive Coronary Care Unit is stressed.

Abstract
BACKGROUND A prospective study has been done on 46 patients with suspected coronary artery disease (CAD). They had no history of myocardial infarction (MI) and a normal basal kinetic echocardiography. This was done in order to evaluate the overall accuracy of dobutamine-atropine stress echocardiography (DAS) compare to exercise stress test (ET) for the diagnosis of CAD. METHODS All the patients after suspension of coronary therapy, performed a casual sequence with both maximal or symptom limited exercise testing (treadmill-Bruce protocol) and DAS. The dobutamine has been given while monitoring systemic blood pressure, electrocardiography and echocardiography in steps of 10 mcg/kg/min' per 3 min' up to a maximum of 40 mcg/kg/min'. Atropine has been added (0.25-1 mg) in patients who did not reach the theoretical maximal cardiac frequency. The test is considered positive when kinetic segmental left ventricular dysfunction appeared. CAD was defined as 50% luminal area stenosis in at least 1 coronary artery at coronary angiography. RESULTS Significant CAD was present in 27/46 patients (59%). Compared with ET, DAS had significantly higher sensitivity (59% vs 92%, p = 0.01). The different sensibility between the two tests was higher on these patients with a 1 vessel disease (40% vs 86%, p = 0.02). There were no significant differences in specificity among the two tests (79% vs 84%, respectively). Differences in overall accuracy between ET and DAS were significant (67% vs 89%, p = 0.02). CONCLUSIONS The results of our study show that the DAS is a safe and feasible technique with high sensibility (especially in patients with single CAD) and specificity. This is a valid alternative to the traditional ET, especially for these patients unable to exercise or these who are poorly motivated to achieve a work load sufficient to make the test interpretable.

Abstract
Although thrombolytic therapy reduces mortality in patients with acute myocardial infarction (AMI), it is associated with a greater incidence of successive coronary events, and there is still no ideal diagnostic and therapeutic strategy for such patients. The present study verifies the value of negative predischarge exercise testing in identifying low-risk patients treated with thrombolysis after AMI. One hundred fifty-seven consecutive patients with an uncomplicated clinical course underwent maximal or symptom-limited exercise testing (Bruce treadmill protocol) within 15 days of AMI in the absence of therapy. The location of the AMI was anterior in 51 patients, inferior in 85 and non-Q-wave in 21. All of the patients were followed for 6 months. Death and nonfatal reinfarction were considered as major coronary events, and the recurrence of angina as a minor event. Exercise test results were negative in 105 patients (group 1) and positive for angina or ST depression greater than or equal to 0.1 mV in 52 (group 2). No deaths occurred during follow-up; there were 3 reinfarctions (3%) and 7 cases (7%) of postinfarction angina in group 1, and 2 reinfarctions (4%) and 21 cases (40%) of postinfarction angina in group 2. By the end of follow-up, 90% of the patients with negative exercise test results were event-free (97% in the case of major events). These results show that thrombolytic therapy does not affect the value of negative postinfarction exercise testing in identifying low-risk patients.
