Association of Incident Cardiovascular Disease With Time Course and Cumulative Exposure to Multiple Risk Factors.

Background: The quantitative relationship of incident cardiovascular disease (CVD) to lifetime cumulative risk factor exposure is not well understood.

Objectives: Using CARDIA (Coronary Artery Risk Development in Young Adults) study data, we examined the quantitative associations of cumulative exposure over time to multiple, simultaneously operating risk factors with CVD incidence and the incidence of its components.

Methods: Regression models were developed quantifying the influence of the time course and severity of multiple CVD risk factors, operating simultaneously, on risk of incident CVD.

Association of Cumulative Systolic Blood Pressure With Long-Term Risk of Cardiovascular Disease and Healthy Longevity: Findings From the Lifetime Risk Pooling Project Cohorts.

Hypertension is a major risk factor for cardiovascular disease (CVD), but previous studies have mostly been limited to a single exam, a single cohort, a short follow-up period, or a limited number of outcomes. This study aimed to assess the association of 10-year cumulative systolic blood pressure (BP) in middle age with long-term risk of any CVD, coronary heart disease, stroke, heart failure, all-cause mortality, and healthy longevity. Individuals (11 502) from 5 racially/ethnically diverse US community-based cohorts were included in this study once they met all the inclusion criteria: ≥10 year of observation in the included cohort, aged 45 to 60 years, free of CVD, and had ≥3 visits with BP exams over the preceding 10 years.

Time Course of LDL Cholesterol Exposure and Cardiovascular Disease Event Risk.

Background: Incident cardiovascular disease (CVD) increases with increasing low-density lipoprotein cholesterol (LDL-C) concentration and exposure duration. Area under the LDL-C versus age curve is a possible risk parameter. Data-based demonstration of this metric is unavailable and whether the time course of area accumulation modulates risk is unknown.

SYNTAX Score in Patients With Diabetes Undergoing Coronary Revascularization in the FREEDOM Trial.

Background: Diabetes mellitus (DM) is associated with complex coronary artery disease (CAD), which in turn results in increased morbidity and mortality from cardiovascular disease.

Objectives: This study sought to evaluate the utility of SYNTAX score (SS) for predicting future cardiovascular events in patients with DM and complex CAD undergoing either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI).

Methods: The FREEDOM (Future REvascularization Evaluation in patients with Diabetes mellitus: Optimal management of Multivessel disease) trial randomized patients with DM and multivessel CAD to undergo either PCI with drug-eluting stents or CABG.

Long-Term Survival Following Multivessel Revascularization in Patients With Diabetes: The FREEDOM Follow-On Study.

Background: The FREEDOM (Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease) trial demonstrated that for patients with diabetes mellitus (DM) and multivessel coronary disease (MVD), coronary artery bypass grafting (CABG) is superior to percutaneous coronary intervention with drug-eluting stents (PCI-DES) in reducing the rate of major adverse cardiovascular and cerebrovascular events after a median follow-up of 3.8 years. It is not known, however, whether CABG confers a survival benefit after an extended follow-up period.

Stroke Rates Following Surgical Versus Percutaneous Coronary Revascularization.

Background: Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are used for coronary revascularization in patients with multivessel and left main coronary artery disease. Stroke is among the most feared complications of revascularization. Due to its infrequency, studies with large numbers of patients are required to detect differences in stroke rates between CABG and PCI.

2017 Cardiovascular and Stroke Endpoint Definitions for Clinical Trials.

This publication describes uniform definitions for cardiovascular and stroke outcomes developed by the Standardized Data Collection for Cardiovascular Trials Initiative and the US Food and Drug Administration (FDA). The FDA established the Standardized Data Collection for Cardiovascular Trials Initiative in 2009 to simplify the design and conduct of clinical trials intended to support marketing applications. The writing committee recognizes that these definitions may be used in other types of clinical trials and clinical care processes where appropriate.

Mortality after coronary artery bypass grafting versus percutaneous coronary intervention with stenting for coronary artery disease: a pooled analysis of individual patient data.

Background: Numerous randomised trials have compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) for patients with coronary artery disease. However, no studies have been powered to detect a difference in mortality between the revascularisation strategies.

Methods: We did a systematic review up to July 19, 2017, to identify randomised clinical trials comparing CABG with PCI using stents.

Associations Between Short or Long Length of Stay and 30-Day Readmission and Mortality in Hospitalized Patients With Heart Failure.

Objectives: This study sought to examine the associations between heart failure (HF)-related hospital length of stay and 30-day readmissions and HF hospital length of stay and mortality rates.

Background: Although reducing HF readmission and mortality rates are health care priorities, how HF-related hospital length of stay affects these outcomes is not fully known.

Methods: A population-level, multicenter cohort study of 58,230 patients with HF (age >65 years) was conducted in Ontario, Canada between April 1, 2003 and March 31, 2012.

Relation of Post-Coronary Artery Bypass Graft Creatine Kinase-MB Elevations and New Q Waves With Long-Term Cardiovascular Death in Patients With Diabetes Mellitus and Multivessel Coronary Artery Disease.

Associations of early creatine phosphokinase-MB (CK-MB) elevation and new Q waves and their association with cardiovascular death (CVD) after coronary artery bypass grafting (CABG) have been reported, but this association has not been studied in a large population of patients with diabetes mellitus. In this study, we examine the association of periprocedural CK-MB elevations and new Q waves with CVD in the Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease trial. Cox proportional hazards regression was used to assess the relation of CK-MB elevations and new Q waves in the first 24 hours after procedure and their relation to CVD; logistic regression was used to assess odds ratios of these variables.

Next Steps in Primary Prevention of Coronary Heart Disease: Rationale for and Design of the ECAD Trial.

Atherosclerotic cardiovascular disease (ASCVD) events, including coronary heart disease and stroke, are the most frequent cause of death and major disability in the world. Current American College of Cardiology/American Heart Association primary prevention guidelines are mainly on the basis of randomized controlled trials of statin-based low-density lipoprotein cholesterol (LDL-C)-lowering therapy for primary prevention of ASCVD events. Despite the clear demonstration of statin-based LDL-C lowering, substantial 10-year and lifetime risks of incident ASCVD continue.

Predictors of stroke associated with coronary artery bypass grafting in patients with diabetes mellitus and multivessel coronary artery disease.

This study assesses demographic and clinical variables associated with perioperative and late stroke in diabetes mellitus patients after multivessel coronary artery bypass grafting (CABG). Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease (FREEDOM) is the largest randomized trial of diabetic patients undergoing multivessel CABG. FREEDOM patients had improved survival free of death, myocardial infarction, or stroke and increased overall survival after CABG compared to percutaneous intervention.

Left ventricular assist devices improve functional class without normalizing peak oxygen consumption.

Heart failure patients supported with left ventricular assist devices (LVAD) enjoy improvements in functional capacity and quality of life. We reasoned that such improvements in exercise capacity should be reflected in an objective increase in peak oxygen consumption as measured by cardiopulmonary exercise testing (CPET). We performed a retrospective review of all recipients of a HeartMate II LVAD at our center from June 2009 to June 2012 who completed CPET.

Long-term outcome of PCI versus CABG in insulin and non-insulin-treated diabetic patients: results from the FREEDOM trial.

Background: The prospective, randomized FREEDOM (Comparison of Two Treatments for Multivessel Coronary Artery Disease in Individuals With Diabetes) trial found coronary artery bypass graft surgery (CABG) was associated with better clinical outcomes than percutaneous coronary intervention (PCI) in patients with diabetes and multivessel disease, managed with or without insulin.

Objectives: In this subgroup analysis of the FREEDOM trial, we examined the association of long-term clinical outcomes after revascularization in patients with insulin-treated diabetes mellitus (ITDM) compared with patients not treated with insulin.

Methods: A total of 1,850 FREEDOM subjects had an index revascularization procedure performed: 956 underwent PCI with drug-eluting stents (DES), and 894 underwent CABG.

Lipoprotein(a) for risk assessment in patients with established coronary artery disease.

Objectives: The purpose of this study was to assess the prognostic utility of lipoprotein(a) [Lp(a)] in individuals with coronary artery disease (CAD).

Background: Data regarding an association between Lp(a) and cardiovascular (CV) risk in secondary prevention populations are sparse.

Methods: Plasma Lp(a) was measured in 6,708 subjects with CAD from 3 studies; data were then combined with 8 previously published studies for a total of 18,978 subjects.

Clinical outcome endpoints in heart failure trials: a European Society of Cardiology Heart Failure Association consensus document.

Endpoint selection is a critically important step in clinical trial design. It poses major challenges for investigators, regulators, and study sponsors, and it also has important clinical and practical implications for physicians and patients. Clinical outcomes of interest in heart failure trials include all-cause mortality, cause-specific mortality, relevant non-fatal morbidity (e.
