Elevated Lp(a): Guidance for Identifying and Managing Patients.

Lipoprotein(a) (Lp(a)) is a unique low-density lipoprotein-like lipoprotein that is considered an independent and causal risk factor for atherosclerotic cardiovascular disease (ASCVD) and calcific aortic valve stenosis. The Lp(a) molecule also contains apolipoprotein A and apolipoprotein B, which collectively promote atherosclerosis, thrombosis, and inflammation. Lp(a) is highly genetic and minimally responsive to nonpharmacological measures.

Understanding D-Ribose and Mitochondrial Function.

Mitochondria are important organelles referred to as cellular powerhouses for their unique properties of cellular energy production. With many pathologic conditions and aging, mitochondrial function declines, and there is a reduction in the production of adenosine triphosphate. The energy carrying molecule generated by cellular respiration and by pentose phosphate pathway, an alternative pathway of glucose metabolism.

Caregiver coaching program effect: Reducing heart failure patient rehospitalizations and improving caregiver outcomes among African Americans.

Objectives: (1) Test whether FamHFcare intervention could reduce patients' heart failure (HF)-related rehospitalizations and improve family caregiver outcomes; (2) calculate effect size on caregiver outcomes; and (3) evaluate the FamHFcare.

Background: Few interventions target family caregivers for HF home care.

Methods: This study was a mixed method design with stratification and random assignment of 20 African American HF patient/caregiver dyads.

Disparities in lipid control and statin drug use among diabetics with noncoronary atherosclerotic vascular disease vs those with coronary artery disease.

Background: Diabetes mellitus (DM), coronary artery disease (CAD), and noncoronary atherosclerotic vascular diseases (NCVDs) have similar risks of cardiovascular events and similar recommendations for lipid control. There are limited data regarding lipid control in diabetic patients with NCVD in current clinical practice.

Objective: To assess current day practice of lipid control in patients with DM with NCVD vs those with CAD.

Multidisciplinary group clinic appointments: the Self-Management and Care of Heart Failure (SMAC-HF) trial.

Background: This trial tested the effects of multidisciplinary group clinic appointments on the primary outcome of time to first heart failure (HF) rehospitalization or death.

Methods And Results: HF patients (n=198) were randomly assigned to standard care or standard care plus multidisciplinary group clinics. The group intervention consisted of 4 weekly clinic appointments and 1 booster clinic at month 6, where multidisciplinary professionals engaged patients in HF self-management skills.

Comparison of accuracy of two different methods to determine ankle-brachial index to predict peripheral arterial disease severity confirmed by angiography.

Ankle-brachial index (ABI) is conventionally derived as the ratio of higher of the 2 systolic ankle blood pressures to the higher brachial pressure (HABI method). Alternatively, ABI may be derived using the lower of the 2 systolic ankle pressures (LABI method). The objective of this study was to assess the utility and difference between 2 techniques in predicting peripheral artery disease (PAD).

Patients' annual income adequacy, insurance premiums and out-of-pocket expenses related to heart failure care.

Objectives: To (1) identify the amount patients spend for insurance premiums, co-payments, deductibles, and other out-of-pocket costs related to HF and chronic health care services and estimate their annual non-reimbursed and out-of-pocket costs; and (2) identify patients' concerns about nonreimbursed and out-of-pocket expenses.

Background: HF is one of the most expensive illnesses for our society with multiple health services and financial burdens for families.

Methods: Mixed methods with quantitative questionnaires and qualitative interviews.

Diet and exercise interventions following coronary artery bypass graft surgery: a review and call to action.

Coronary artery bypass graft (CABG) surgery has been used for the treatment of coronary artery disease (CAD) for approximately 50 years, and has been performed on millions of people globally. However, little is known about the impact of diet and exercise on long-term outcomes of patients who have undergone CABG surgery. Although clinical practice guidelines on the management of this patient population have been available for approximately 2 decades, evidence regarding secondary prevention behavioral interventions, lifestyle modifications and self-management to slow the progressive decline of CAD, reduce cardiac hospitalizations, and prevent reoperation remains virtually absent from the literature.

Comparison of lipid management in patients with coronary versus peripheral arterial disease.

Peripheral arterial disease (PAD), similar to coronary artery disease (CAD), is a significant predictor of cardiovascular morbidity and mortality. Guidelines recommend a low-density lipoprotein (LDL) goal of <100 mg/dl for both groups. We assessed whether lipid control and statin use were as aggressively applied to PAD as to patients with CAD.

Anticoagulation and antiplatelet therapy in acute coronary syndromes.

Antiplatelet and anticoagulant drugs are the mainstay of treatment of acute coronary syndrome (ACS). The last 30 years have seen the development of various agents, a deeper understanding of the pathobiology of this disease, and an evolution in its treatment. We review the role of contemporary agents in ACS and highlight key clinical trials of these agents.

Hypertension medication use and adherence among adults with developmental disability.

Background/objective: Adults with developmental disability (DD) have high prevalence of coronary artery disease risk factors, as well as impediments to optimal diagnosis and management. We analyzed antihypertensive medication (AM) use and adherence patterns in a Kansas Medicaid cohort.

Methods: We studied adults (18-64 years) with DD and claims for HT from 7/1/05 to 8/31/06, with review of prescription records of AM use and adherence from 9/1/06 to 8/31/07.

Ezetimibe in combination with a statin does not reduce all-cause mortality.

Background: Although the ezetimibe-statin combination has been shown to reduce LDL cholesterol by 12% compared to a statin alone, its effect on hard clinical endpoints such as mortality is less certain. Prior trials evaluated this combination in highly select population groups, but impact on all- cause mortality in the general population has not been reported.

Methods: A total of 3,827 subjects who were prescribed either a statin (group 1) or the combination of statin with ezetimibe (group 2) between January 1st, 2005 and January 1st, 2008 were studied.

Calcium affects on vascular endpoints.

Calcium is one of the most abundant minerals in the body and its metabolism is one of the basic biologic processes in humans. Although historically linked primarily to bone structural development and maintenance, calcium is now recognized as a key component of many physiologic pathways necessary for optimum health including cardiovascular, neurological, endocrine, renal, and gastrointestinal systems. A recent meta-analysis published in August 2011 showed a potential increase in cardiovascular events related to calcium supplementation.

Imaging techniques in acute coronary syndromes: a review.

Coronary heart disease (CHD) remains the leading cause of death in the United States. National review of Emergency Department (ED) visits from 2007 to 2008 reveals that 9% are for chest pain. Of these patients, 13% had acute coronary syndromes (ACSs) (Antman et al.

Vitamin D deficiency and supplementation and relation to cardiovascular health.

Recent evidence supports an association between vitamin D deficiency and hypertension, peripheral vascular disease, diabetes mellitus, metabolic syndrome, coronary artery disease, and heart failure. The effect of vitamin D supplementation, however, has not been well studied. We examined the associations between vitamin D deficiency, vitamin D supplementation, and patient outcomes in a large cohort.

Preoperative Statin use is not Associated with a Reduced Risk of Atrial Fibrillation After Cardiac Surgery.

Postoperative atrial fibrillation (POAF) is prevalent after cardiac surgery and associated with significant morbidity and costs. Statins are commonly used in this population and may be a preventative strategy for PAOF. We wished to examine the effect of preoperative statin use on the risk of POAF after cardiac surgery.

Impact of bisphosphonates on the risk of atrial fibrillation.

Osteoporosis is a major public health problem resulting in significant morbidity, mortality, and utilization of healthcare resources. Bisphosphonates are the most widely prescribed drugs for increasing bone mass and preventing osteoporosis-related fractures. Although these drugs have proven efficacy and are generally considered safe, a clinical trial of once-yearly zoledronic acid reported an unexpected increase in the risk of cardiac arrhythmias, primarily due to serious atrial fibrillation (AF).

Electrocardiographic changes with the onset of diabetes and the impact of aerobic exercise training in the Zucker Diabetic Fatty (ZDF) rat.

Background: Early markers of diabetic autonomic neuropathy (DAN) in an electrocardiogram (ECG) include elevated R wave amplitudes, widening of QTc intervals and decreased heart rate variability (HRV). The severity of DAN has a direct relationship with mortality risk. Aerobic exercise training is a common recommendation for the delay and possible reversal of cardiac dysfunction.

Role of vitamin D in cardiovascular health.

Observational studies strongly associate vitamin D deficiency with a variety of cardiovascular diseases beyond defects in bone and calcium metabolism. Vitamin D has multiple mechanisms that potentially may affect cardiovascular health. Because vitamin D deficiency is common, therapies directed at the replacement of vitamin D may be beneficial.

Approach to incidentally diagnosed isolated ventricular noncompaction of myocardium.

Isolated ventricular noncompaction (IVNC) is a congenital cardiomyopathy characterized by a distinctive ("spongy") morphological appearance of the left ventricular (LV) myocardium. It is rare but, with improved imaging modalities and awareness, it is being reported more frequently. Clinical manifestations may range from being asymptomatic to heart failure, arrhythmias, sudden cardiac death, and systemic thromboembolism.
