Clinical outcomes, pharmacological treatment, and quality of life of patients with stable coronary artery diseases managed by cardiologists: 1-year results of the START study

Perfect health not so perfect after all - a methodological study on patient-reported outcome measures in 2574 patients following percutaneous coronary intervention

BACKGROUND

Patient-reported outcome measures (PROMs) are crucial to capture patients' health and illness status. Selecting the most suitable PROM to measure self-reported health in a specific study population is essential. Shortcomings of much used generic instruments have been identified in certain populations, and more investigation is needed to clarify the extent to which the generic instruments capture the aspects of health that really matter to patients. Therefore, the aim of this study was to determine floor and ceiling effects of a generic health utility instrument (EQ-5D-5L) in an international multi-centre cohort of patients after percutaneous coronary intervention (PCI) and further explore those with perfect health scores by using a disease-specific instrument.

METHODS

The CONCARDPCI study was conducted at seven large referral PCI centres in Norway and Denmark between June 2017 and May 2020. In all, 2574 unique patients were available for this analysis. The generic EQ-5D-5L descriptive system and visual analogue scale, and the disease-specific Myocardial Infarction Dimensional Assessment Scale (MIDAS) comprising 35 items measuring seven areas of health status and daily life challenges were used to scrutinize the aims. Latent class analyses were conducted to identify classes with similar patterns of daily life challenges based on MIDAS item scores within the group of patients with best possible EQ-5D-5L score ('perfect scorers').

RESULTS

There was a large ceiling effect on the EQ-5D-5L score in patients with coronary artery disease (CAD) with 32% scoring the best possible EQ-5D-5L score, suggesting perfect health. Latent class analysis on the MIDAS revealed, however, four classes where 17-46% of the perfect scorers did perceive challenges in health, particularly related to symptoms of fatigue, and worries about risk factors and side effects of medication.

CONCLUSION

To obtain an accurate picture of patients' health status, these results emphasize that both generic and disease-specific patient-reported outcomes measures are needed to capture the distinct problems that patients with CAD experience after PCI. Caution should be made when using the EQ-5D-5L as the sole measure, particularly in priority settings, due to its potential ceiling effect and the fact that important aspects of patient health may be neglected.

Prevalence and predictive role of hypertriglyceridemia in statin-treated patients at very high risk: Insights from the START study

BACKGROUND AND AIM

Elevated triglyceride (TG) levels seem to identify subjects at increased cardiovascular risk, independent of LDL-C levels. We sought to evaluate the predictive role of hypertriglyceridemia, defined as TG levels ≥150 mg/dl, in very high risk (VHR) patients with chronic coronary syndromes (CCS) treated with statins.

METHODS AND RESULTS

Using the data from the STable Coronary Artery Diseases RegisTry (START) study, an Italian nationwide registry, we assessed the association between the TG levels and baseline clinical characteristics, pharmacological treatment and major adverse cardio-cerebrovascular events (MACCE) at 1 year in a large cohort of statin-treated patients at VHR. Of the 4751 consecutive patients with CCS enrolled in the registry and classified as VHR, 2652 (55.8%) had TG values available (mean 120.6 ± 54.9) and were treated with at least a statin at baseline: 2019 (76.1%) with TG < 150 and 633 (23.9%) with TG ≥ 150 mg/dl. At 1 year from enrolment, MACCE occurred in 168 (6.3%) patients, without differences between the two groups of TG (5.9 vs 7.6%; p = 0.14). At multivariable analysis, hypertriglyceridemia did not result as independent predictor of the MACCE (hazard ratio: 1.16; 95% confidence intervals: 0.82-1.64; p = 0.42).

CONCLUSIONS

In the present large, nationwide cohort of consecutive CCS patients at VHR with statin-controlled LDL-C levels, hypertriglyceridemia was present in around 24% of cases and did not result as predictor of MACCE at 1 year. Further studies with a longer follow-up and larger sample size are needed to better define the prognostic role of TG levels when intensive LDL lowering therapies are used.

Efficacy and safety of Shexiang Baoxin Pill for stable coronary artery disease: A systematic review and meta-analysis of 42 randomized controlled trials

Objective: Patients with stable coronary artery disease (SCAD) still have a higher risk of adverse cardiovascular events. Shexiang Baoxin Pill (SBP) is widely used as a complementary and alternative treatment for SCAD. This study aimed to further verify the therapeutic effect and safety of SBP on SCAD. Methods: Seven databases were involved in this meta-analysis as of 1 June 2022. Data was collected from all the randomized controlled trials (RCTs) of the combination of SBP and conventional western medicine (CWM) in treating SCAD which was conducted by two independent authors. Risk of bias was assessed using the Cochrane risk-of-bias 2.0 (RoB2.0) tool, and the meta-analysis was accomplished with Review Manager 5.3. Furthermore, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) profiler 3.2.2 software was selected to grade the current evidence in our findings. Results: 42 articles, involving 6,694 patients were screened among all the 1,374 records in the analysis. The results demonstrated that the combination therapy was more efficient than CWM alone in lowering the incidence of major adverse cardiovascular events (MACE, RR = 0.50, 95% CI: 0.37 to 0.68, p < 0.00001) and ameliorating the total effective rate of angina symptom improvement (RR = 1.23, 95% CI: 1.19 to 1.28, p < 0.00001), the effective rate of electrocardiogram improvement (RR = 1.34, 95% CI: 1.26 to 1.43, p < 0.00001), the frequency of angina pectoris (MD = -2.83, 95% CI: -3.62 to -2.05, p < 0.00001), and the duration of angina pectoris (MD = -1.32, 95% CI: -2.04 to -0.61, p = 0.0003). We also found that, after SBP treatment, a more positive blood lipid level and left ventricular ejection fraction without the increase in adverse cases were calculated in our meta-analysis. What's more, Subgroup analysis indicated that treatment duration may be the source of heterogeneity. The certainty of the evidence for MACE, and electrocardiogram improvement exhibited moderate certainty, and the certainty of the evidence for the remaining outcomes was judged as low certainty. The trial sequential analysis further affirmed the clinical efficacy of SBP. Conclusion: The available evidence indicates that SBP may be an effective therapeutic option in patients with SCAD. However, considering the inferior quality and inconsistent results in the included trials, further rigorous RCTs are required.

Fat-to-muscle ratio as a predictor for dyslipidaemia in transitional-age youth

Background

Although dyslipidaemia may have a crucial impact on cardiovascular health in adults, there is a lack of specific data in transitional-age youth. Therefore, this study attempted to evaluate the association of dyslipidaemia with fat-to-muscle ratio (FMR), and establish FMR thresholds for diagnosing dyslipidaemia in transitional-age youth.

Methods

One thousand six hundred sixty individuals aged 16 to 24 years from the baseline of a subcohort in the Northwest China Natural Population Cohort: Ningxia Project were analysed. Anthropometric characteristics were gauged by a bioelectrical impedance analyser, and dyslipidaemia components were measured using a Beckman AU480 chemistry analyser. Additionally, this study used logistic regression to estimate the risk of dyslipidaemia based on FMR quintiles, and calculate the gender-specific ideal cut-off values of dyslipidaemia and its components by the receiver operating characteristic (ROC) curve.

Results

Of the 1660 participants, aged 19.06 ± 1.14 years, 558 males and 1102 females. The prevalence of dyslipidaemia was 13.4% and was significantly associated with FMR quintiles among all participants (P < 0.05). The ideal values of FMR in diagnosing dyslipidaemia were 0.2224 for males and 0.4809 for females, while males had a higher AUC than females (0.7118 vs. 0.6656). Meanwhile, high FMR values were significantly associated with adverse outcomes of dyslipidaemia, hypercholesterolemia and hypertriglyceridaemia (P < 0.05).

Conclusions

The FMR was positively correlated with the prevalence of dyslipidaemia. The FMR can be used as an effective body composition index for diagnosing dyslipidaemia, especially in males, and preventive strategies should be initiated in transitional-age youth to decrease obesity-related dyslipidaemia.

Impact of eGFR rate on 1-year all-cause mortality in patients with stable coronary artery disease

BACKGROUND

Coronary artery disease (CAD) is a leading cause of mortality and is often complicated by chronic kidney disease. We sought to investigate the prevalence of different degree of estimated glomerular filtration rate (eGFR) reduction, the clinical and bio-humoral correlates, its relationship with therapeutic management, and its predictive role on 1-year all-cause mortality, in patients with stable CAD.

METHODS

We studied 4,130 patients with stable CAD recruited in a prospective, observational, nationwide study (START, STable coronary Artery diseases RegisTry) in Italy. Baseline clinical characteristics, pharmacological treatment, and all-cause 1-year mortality were evaluated according to groups of eGFR (<30; 30-59; 60-89; ≥90 ml/min/1.73 m²) at baseline.

RESULTS

The presence and the degree of chronic kidney disease entailed an unfavorable risk profile, since it was gradually associated with more comorbidities. Furthermore, progressively lower eGFR values were associated to lower diastolic blood pressure and hemoglobin values. As eGFR lowers, optimal medical treatment and its persistence overtime is reduced. Multivariate analysis showed that progressively lower eGFR significantly correlated with all-cause 1-year mortality [hazard ratio (HR): 1.02; 95% confidence intervals (CI): 1.01-1-03; p = 0.0001].

CONCLUSIONS

Low eGFR is associated with an increasing risk of all-cause mortality in patients with stable CAD. Chronic kidney disease may hamper the optimization of treatment limiting the use of drugs which may favorably impact cardiovascular and renal outcomes.

Clinical Impact and Prognostic Role of Triglyceride to High-Density Lipoprotein Cholesterol Ratio in Patients With Chronic Coronary Syndromes at Very High Risk: Insights From the START Study

Background

Several studies have reported that the combination of high TG and low HDL-C, as simplified by the TG/HDL-C ratio, was a predictor of cardiovascular disease independent of LDL-C level. Nevertheless, poor data are available on the predictive role of TG/HDL-C ratio in very high risk (VHR) patients with chronic coronary syndromes (CCS).

Methods

Using the data from the STable Coronary Artery Diseases RegisTry (START) study, an Italian nationwide registry, we assessed the association between the TG/HDL-C ratio and baseline clinical characteristics, pharmacological treatment, and major adverse cardio-cerebrovascular events (MACCE) at 1 year in a large cohort of CCS patients at VHR.

Results

VHR patients with both TG and HDL-C levels available were grouped in tertiles of TG/HDL-C ratio: low (TG/HDL-C ratio &lt;2, n = 967), middle (TG/HDL-C ratio 2–3.3, n = 1,071) and high (TG/HDL-C ratio &gt;3.3, n = 1,028). At 1 year from enrolment, 232 (7.6%) patients presented a MACCE, with a higher incidence in the higher tertile, even though not statistically significant (6.0, 8.2, and 8.4% in the low, middle and high tertile, respectively; p = 0.08). At multivariable analysis, the TG/HDL-C ratio in tertiles did not result an independent predictor of the MACCE (p = 0.29) at 1-year follow-up (HR: 1.30; 95% CI: 0.93–1.82; p = 0.12 middle vs. lower tertile, and HR: 1.22; 95% CI: 0.87–1.72; p = 0.25 higher vs. lower).

Conclusions

In the present large, nationwide cohort of CCS patients at VHR a high TG/HD ratio did not emerge as independent predictor of MACCE at 1 year. Further studies with a longer follow-up are needed to better define the prognostic role of TG/HDL ratio in CCS.

Impact of serum uric acid levels on cardiovascular events and quality of life in patients with chronic coronary syndromes: Insights from a contemporary, prospective, nationwide registry

BACKGROUND AND AIMS

Hyperuricemia is a metabolic disorder that has been associated with adverse cardiovascular (CV) events. Using the data from a nationwide, prospective registry on patients with chronic coronary syndromes (CCS), we assessed the impact of serum uric acid (SUA) levels on quality of life (QoL) and major adverse CV events (MACE), a composite of CV death and hospitalization for myocardial infarction, heart failure (HF), angina or revascularization at 1-year.

METHODS AND RESULTS

Among the 5070 consecutive CCS patients enrolled in the registry, levels of SUA were available for 2394 (47.2%). Patients with SUA levels available at baseline were grouped as low tertile (n = 860; 4.3 [3.7-4.7] mg/dL), middle tertile (n = 739; 5.6 [5.3-5.9] mg/dL) and high tertile (n = 795; 7.1 [6.7-7.9] mg/dL). At 1 year, the incidence of MACE was 3.7%, 4.1% and 6.8% for low, middle and high tertiles, respectively (p = 0.005 for low vs high tertile). Patients in the high tertile of SUA had a significantly higher rate of CV mortality (1.4% vs 0.4%; p = 0.05) and hospital admission for HF (2.8% vs 1.6%; p = 0.03) compared to the low tertile. However, hyperuricemia did not result as an independent predictor of MACE at multivariable analysis [hazard ratio: 1.27; 95% confidence intervals: 0.81-2.00; p = 0.3].

CONCLUSIONS

In this contemporary, large cohort of CCS, those in the high tertile of SUA had a greater burden of CV disease and worse QoL. However, SUA did not significantly influence the higher rate of CV mortality, hospitalization for HF and MACE observed in these patients during 1-year follow-up.

COMPASS criteria applied to a contemporary cohort of unselected patients with stable coronary artery diseases: insights from the START registry

AIMS

Recently, the cardiovascular outcomes for people using anticoagulation strategies (COMPASS) trial demonstrated that dual therapy reduced cardiovascular outcomes compared with aspirin alone in patients with stable atherosclerotic disease.

METHODS AND RESULTS

We sought to assess the proportion of patients eligible for the COMPASS trial and to compare the epidemiology and outcome of these patients with those without COMPASS inclusion or with any exclusion criteria in a contemporary, nationwide cohort of patients with stable coronary artery disease. Among the 4068 patients with detailed information allowing evaluation of eligibility, 1416 (34.8%) did not fulfil the inclusion criteria (COMPASS-Not-Included), 841 (20.7%) had exclusion criteria (COMPASS-Excluded), and the remaining 1811 (44.5%) were classified as COMPASS-Like. At 1 year, the incidence of major adverse cardiovascular event (MACE), a composite of cardiovascular death, myocardial infarction, and stroke, was 0.9% in the COMPASS-Not-Included and 2.0% in the COMPASS-Like (P = 0.01), and 5.0% in the COMPASS-Excluded group (P < 0.0001 for all comparisons). Among the COMPASS-Like population, patients with multiple COMPASS enrichment criteria presented a significant increase in the risk of MACE (from 1.0% to 3.3% in those with 1 and ≥3 criteria, respectively; P = 0.012), and a modest absolute increase in major bleeding risk (from 0.2% to 0.4%, respectively; P = 0.46).

CONCLUSION

In a contemporary real-world cohort registry of stable coronary artery disease, most patients resulted as eligible for the COMPASS. These patients presented a considerable annual risk of MACE that consistently increases in the presence of multiple risk factors.

P2Y12 inhibitor monotherapy or dual antiplatelet therapy after coronary revascularisation: individual patient level meta-analysis of randomised controlled trials

OBJECTIVE

To assess the risks and benefits of P2Y₁₂ inhibitor monotherapy compared with dual antiplatelet therapy (DAPT) and whether these associations are modified by patients' characteristics.

DESIGN

Individual patient level meta-analysis of randomised controlled trials.

DATA SOURCES

Searches were conducted in Ovid Medline, Embase, and three websites (www.tctmd.com, www.escardio.org, www.acc.org/cardiosourceplus) from inception to 16 July 2020. The primary authors provided individual participant data.

ELIGIBILITY CRITERIA

Randomised controlled trials comparing effects of oral P2Y₁₂ monotherapy and DAPT on centrally adjudicated endpoints after coronary revascularisation in patients without an indication for oral anticoagulation.

MAIN OUTCOME MEASURES

The primary outcome was a composite of all cause death, myocardial infarction, and stroke, tested for non-inferiority against a margin of 1.15 for the hazard ratio. The key safety endpoint was Bleeding Academic Research Consortium (BARC) type 3 or type 5 bleeding.

RESULTS

The meta-analysis included data from six trials, including 24 096 patients. The primary outcome occurred in 283 (2.95%) patients with P2Y₁₂ inhibitor monotherapy and 315 (3.27%) with DAPT in the per protocol population (hazard ratio 0.93, 95% confidence interval 0.79 to 1.09; P=0.005 for non-inferiority; P=0.38 for superiority; τ²=0.00) and in 303 (2.94%) with P2Y₁₂ inhibitor monotherapy and 338 (3.36%) with DAPT in the intention to treat population (0.90, 0.77 to 1.05; P=0.18 for superiority; τ²=0.00). The treatment effect was consistent across all subgroups, except for sex (P for interaction=0.02), suggesting that P2Y₁₂ inhibitor monotherapy lowers the risk of the primary ischaemic endpoint in women (hazard ratio 0.64, 0.46 to 0.89) but not in men (1.00, 0.83 to 1.19). The risk of bleeding was lower with P2Y₁₂ inhibitor monotherapy than with DAPT (97 (0.89%) v 197 (1.83%); hazard ratio 0.49, 0.39 to 0.63; P<0.001; τ²=0.03), which was consistent across subgroups, except for type of P2Y₁₂ inhibitor (P for interaction=0.02), suggesting greater benefit when a newer P2Y₁₂ inhibitor rather than clopidogrel was part of the DAPT regimen.

CONCLUSIONS

P2Y₁₂ inhibitor monotherapy was associated with a similar risk of death, myocardial infarction, or stroke, with evidence that this association may be modified by sex, and a lower bleeding risk compared with DAPT.

Impact of history of depression on 1-year outcomes in patients with chronic coronary syndromes: An analysis of a contemporary, prospective, nationwide registry

BACKGROUND

Depression is common in patients with acute cardiovascular conditions and it is associated with adverse clinical events.

METHODS

Using the data from a nationwide, prospective registry on patients with chronic coronary syndromes (CCS), we assessed the impact of depression on major adverse cardiovascular events (MACE), a composite of all-cause death and hospitalization for myocardial infarction, revascularization, heart failure or stroke, and quality of life (QoL) at 1-year follow-up.

RESULTS

From the 5070 consecutive CCS patients enrolled in the registry, 531 (10.5%) presented a history of depression and the remaining 4539 (89.5%) did not. At 1 year (median 369; IQR 362-378 days) from enrolment, the incidence of the primary composite outcome was 9.8% for patients with a history of depression and 7.2% for non-depressed patients (p = 0.03). Patients with history of depression had a significantly higher rate of all-cause mortality (3.0% vs 1.4%; p = 0.004) and hospital admission for heart failure (3.4% vs 1.3%; p = 0.0002) compared to the group without depression. However, history of depression did not result as an independent predictor of MACE at multivariable analysis [hazard ratio 1.17, 95% confidence interval (0.87-1.58), p = 0.31]. Depressed patients had worse QoL according to all domains of the EQ. 5D-5L questionnaire as compared to non-depressed patients (all p < 0.001), at both enrolment and follow-up.

CONCLUSIONS

In this contemporary, large cohort of consecutive patients with CCS, patients with a history of depression experienced a two-fold rate of mortality, a higher incidence of MACE and a worse QoL at 1-year follow-up, compared to non-depressed patients.

External applicability of the ISCHEMIA trial: an analysis of a prospective, nationwide registry of patients with stable coronary artery disease

AIMS

We sought to assess the proportion of patients eligible for the ISCHEMIA trial and to compare the characteristics and outcomes of these patients with those without ISCHEMIA inclusion or with ISCHEMIA exclusion criteria in a contemporary, nationwide cohort of patients with stable coronary artery disease (CAD).

METHODS AND RESULTS

Among the 5,070 consecutive patients enrolled in the START registry, 4,295 (84.7%) did not fulfil the inclusion criteria (ISCHEMIA-Not Included or ISCHEMIA-Unclassifiable), 582 (11.5%) had exclusion criteria (ISCHEMIA-Excluded), and the remaining 193 (3.8%) were classified as ISCHEMIA-Like. At one year, the incidence of the primary outcome, a composite of death from cardiovascular (CV) causes, myocardial infarction (MI), or hospitalisation for unstable angina and heart failure, was 0.5% in the ISCHEMIA-Like versus 3.3% in other patients (p=0.03). The composite secondary outcome of CV mortality and MI occurred in 0.5% of the ISCHEMIA-Like patients and in 1.4% of the remaining patients (p=0.1).

CONCLUSIONS

In a contemporary real-world cohort of stable CAD patients, only 4% resulted in being eligible for the ISCHEMIA trial. These patients presented an extremely low annual risk of adverse events, especially when compared with other groups of stable CAD patients.

The attributes of hospital-based coronary artery diseases registries with a focus on key registry processes: A systematic review

BACKGROUND

The management of data on coronary artery disease (CAD) plays a significant role in controlling the disease and reducing the mortality of patients. The diseases registries facilitate the management of data.

OBJECTIVE

This study aimed to identify the attributes of hospital-based CAD registries with a focus on key registry processes.

METHOD

In this systematic review, we searched for studies published between 2000 and 2019 in PubMed, Scopus, EMBASE and ISI Web of Knowledge. The search terms included coronary artery disease, registry and data management (MeSH terms) at November 2019. Data gathering was conducted using a data extraction form, and the content of selected studies was analysed with respect to key registry processes, including case finding, data gathering, data abstracting, data quality control, reporting and patient follow-up.

RESULTS

A total of 17,604 studies were identified in the search, 55 of which were relevant studies that addressed the 21 registries and were selected for the analysis. Results showed that the most common resources for case finding included admission and discharge documents, physician's reports and screening results. Patient follow-up was mainly performed through direct visits or via telephone calls. The key attributes used for checking the data quality included data accuracy, completeness and definition.

CONCLUSION

CAD registries aim to facilitate the assessment of health services provided to patients. Putting the key registry processes in place is crucial for developing and implementing the CAD registry. The data quality control, as a CAD registry process, requires developing standard tools and applying appropriate data quality attributes.

IMPLICATIONS

The findings of the current study could lay the foundation for successful design and development of CAD registries based on the key registry processes for effective data management.

One-year clinical events and management of patients with atrial fibrillation hospitalized in cardiology centers: Data from the BLITZ-AF study

BACKGROUND

The management of atrial fibrillation (AF) has changed with the introduction of direct anticoagulants (DOACs) and new techniques such as catheter ablation. An update collection of data from "real world" AF patients followed by cardiologists is useful to obtain information on both management, outcomes and guideline adherence in clinical practice.

METHODS

Follow-up information on survival, embolic and bleeding events and hospital readmission, persistence of oral anticoagulant (OAC) therapy was collected in 84 centers participating to the BLITZ-AF study.

RESULTS

Patients were followed for a median of 366 days (IQR: 356-378) and vital status was available for 2159 patients. Mortality was 9.2%. Heart failure was the most common cardiovascular cause of death (70%) followed by arrhythmias (6.7%), acute coronary syndrome (5.0%) and ischemic stroke (2.5%). During follow-up 18.1% of the patients were readmitted, mainly (81.3%) for cardiovascular causes. Patients on OAC were 83.4%, 9.1% were on antiplatelets and 7.5% did not receive antithrombotic therapy. The use of DOACs increased from 42.1% to 46.4% during the follow-up, OAC discontinuation occurred in 9.1%. AF recurrences occurred in 23.4% of the patients discharged in sinus rhythm. Rate control strategy was adopted in 55.9% and beta-blockers were the most used drugs (81.9%). Amiodarone (22%) and flecainide (9.7%) were the most frequent used antiahrrythmic drugs.

CONCLUSIONS

The follow-up of the BLITZ-AF study provide an up to date picture of the clinical course of patients with AF, who appear frequently affected by heart failure and severe comorbidities which might have led to the high mortality rate.
