On February 9, 2010, the US Food and Drug Administration (FDA) extended its approval of rosuvastatin to include the indication for reducing the risk of stroke, myocardial infarction (MI), and revascularization procedures in individuals who have normal low-density lipoprotein cholesterol (LDL-C) levels and no clinically evident coronary heart disease but have an increased risk based on age, high-sensitivity C-reactive protein (hsCRP) levels, and the presence of at least 1 additional cardiovascular disease risk factor. 1 The decision by the FDA was based on results from the Justification for the Use of Statins in Primary Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER) study, which demonstrated a 44% risk reduction in the primary end point in 17802 primary prevention patients randomly allocated to treatment with rosuvastatin, 20 mg, compared with placebo. 2 .

BACKGROUND Heart failure (HF) in its chronic form is an irreversible and progressive disease. Palliative care (PC) interventions have traditionally been focused on patients with advanced cancer. We performed a pilot study to assess the feasibility of implementing the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for early PC intervention in patients with advanced HF who were seeking or received potentially curative therapies. METHODS Twenty consecutive patients with advanced HF referred to PC from the heart transplant service with stage D, New York Heart Association (NYHA) class III-IV symptoms were analyzed retrospectively in a tertiary care setting. Data were reviewed to assess the clinical impact of PC intervention. Feedback was obtained to assess satisfaction of the patients, their families, and the health care professionals. An independent assessment of the impact of the PC service in the care of each patient was performed by a cardiologist and PC physician by use of a scoring system. RESULTS Twenty consecutive patients with HF were analyzed. PC consult was obtained for a variety of reasons. All patients complained of a high symptom burden. PC consultation resulted in a decrease in the use of opioids and increased patient satisfaction. Patients and their family members generally reported improved holistic care, continuity of care, more focused goals of care, and improved planning of treatment courses. The nonstandardized scoring system used to determine the impact of the PC service showed an average of moderate to significant impact when assessed by both a cardiologist and a PC physician. CONCLUSION PC consultation appears to be beneficial in the treatment and quality of life of advanced HF patients, independent of their prognosis. This pilot study demonstrated feasibility and sufficient evidence of clinical benefit to warrant a larger randomized clinical trial assessing the benefit of standard involvement by PC in patients with advanced HF, independent of the patients prognosis or treatment goals.

Heart failure (HF) with preserved ejection fraction (EF) has a high prevalence in the geriatric population, and this cohort may be at risk of complications caused by polypharmacy. Effects of commonly used cardiac medications on long-term survival of patients >80 years with HF and preserved left ventricular EF were assessed. One hundred forty-two patients were evaluated. During a 5-year follow-up, 98 patients died (69%). There were no significant differences in baseline parameters in patients who died compared with those who survived at 5 years. None of the drug therapies appeared to make a significant difference in long-term survival, including beta blockers (p = 0.89), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (p = 0.91), calcium channel blockers (p = 0.69), diuretics (p = 0.30), digoxin (p = 0.22), and statins (p = 0.32). In conclusion, based on the present data, it appears that use of certain common cardiac medications may not be associated with a significant effect on long-term survival in octogenarians with HF and preserved EF.

The first case of noncompaction was described in 1932 after an autopsy performed on a newborn infant with aortic atresia/coronary–ventricular fistula. Isolated noncompaction cardiomyopathy was first described in 1984. A review on selected/relevant medical literature was conducted using Pubmed from 1984 to 2013 and the pathogenesis, clinical features, and management are discussed. Left ventricular noncompaction (LVNC) is a relatively rare congenital condition that results from arrest of the normal compaction process of the myocardium during fetal development. LVNC shows variability in its genetic pattern, pathophysiologic findings, and clinical presentations. The genetic heterogeneity, phenotypical overlap, and variety in clinical presentation raised the suspicion that LVNC might just be a morphological variant of other cardiomyopathies, but the American Heart Association classifies LVNC as a primary genetic cardiomyopathy. The familiar type is common and follows a X-linked, autosomal-dominant, or mitochondrial-inheritance pattern (in children). LVNC can occur in isolation or coexist with other cardiac and/or systemic anomalies. The clinical presentations are variable ranging from asymptomatic patients to patients who develop ventricular arrhythmias, thromboembolism, heart failure, and sudden cardiac death. Increased awareness over the last 25 years and improvements in technology have increased the identification of this illness and improved the clinical outcome and prognosis. LVNC is commonly diagnosed by echocardiography. Other useful diagnostic techniques for LVNC include cardiac magnetic resonance imaging, computerized tomography, and left ventriculography. Management is symptom based and patients with symptoms have a poorer prognosis. LVNC is a genetically heterogeneous disorder which can be associated with other anomalies. Making the correct diagnosis is important because of the possible associations and the need for long-term management and screening of living relatives.

Heart failure (HF) is a complex syndrome characterized by the inability of the heart to maintain a normal cardiac output without elevated intracardiac filling pressures, resulting in signs of pulmonary and peripheral edema and symptoms of dyspnea and fatigue. Central to the management of HF is a multifaceted pharmacological intervention to abate the harmful counter-regulatory effects of neurohormonal activation and avid salt and water retention. Whereas up to 40 years ago HF was managed with diuretics and leaf of digitalis, the cornerstones of therapy for HF patients with systolic dysfunction now include ACE inhibitors or angiotensin II type 1 receptor antagonists (angiotensin receptor blockers), β-adrenoceptor antagonists (β-blockers), and aldosterone antagonists, which have significantly improved survival. However, with the increasing number of beneficial therapies, there are challenges to implementing all of them. Specific cardiomyopathies also merit specific considerations with respect to treatment, and — unfortunately — there is no therapy for HF with preserved left ventricular ejection fraction that has been shown to improve survival. Although mortality has improved in HF, the biggest challenge to treatment lies in addressing the morbidity of this disease, which is now the most common reason for hospital admission in our aged population. As such, there are many therapies that may serve to improve the quality of life of HF patients. Future HF treatment regimens may include direct cellular therapy via hormone and cytokine signaling or cardiac regeneration through growth factors or cell therapy.

Heart failure is a chronic clinical syndrome with very poor prognosis. Despite being on optimal medical therapy, many patients still experience debilitating symptoms and poor quality of life. In recent years, there has been a great interest in anabolic hormone replacement therapy – namely, growth hormone and testosterone – as an adjunctive therapy in patients with advanced heart failure. It has been observed that low levels of growth hormone and testosterone have been associated with increased mortality and morbidity in patients with heart failure. Animal studies and clinical trials have shown promising clinical improvement with hormonal supplementation. Growth hormone has been shown to increase ventricular wall mass, decrease wall stress, increase cardiac contractility, and reduce peripheral vascular resistance, all of which might help to enhance cardiac function, resulting in improvement in clinical symptoms. Likewise, testosterone has been shown to improve hemodynamic parameters via reduction in peripheral vascular resistance and increased coronary blood flow through vasodilation, thereby improving functional and symptomatic status. To date, growth hormone and testosterone therapy have shown some positive benefits, albeit with some concerns over adverse effects. However, large randomized controlled trials are still needed to assess the long-term safety and efficacy.

The JUPITER trial is widely hailed as a landmark trial that has the potential to dramatically change the landscape of primary prevention of cardiovascular disease. Like most trials, however, it is not without its limitations. We address some of the common myths and misunderstandings that are underscored by the JUPITER trial. First, by its intentional and ill-advised exclusion of patients with low levels of high-sensitivity C-reactive protein (hsCRP), it is not possible to assess whether baseline hsCRP modifies treatment response to statins or whether it identifies patients most likely to benefit from statin therapy. Second, by stopping the trial early, one cannot rule out the possibility that the treatment benefit was overestimated and risk was underestimated, thereby precluding a reliable estimate of benefit/risk. Finally, as a consequence of early stopping, it is not possible to reliably assess the cost-effectiveness of primary prevention with rosuvastatin. Given these limitations, the attendant societal health policy implications remain largely unknown.

Objective: Our aim was to compare the long‐term outcomes between drug‐eluting stents and bare‐metal stents for saphenous vein graft stenosis. Background: The ideal type of stent to treat saphenous vein graft stenosis has not been clearly established. Short‐term randomized controlled trial results comparing drug‐eluting stents with bare‐metal stents for saphenous vein graft stenosis are conflicting, intermediate‐term retrospective studies and meta‐analyses at two years suggest no difference in outcomes, and there are no long term follow‐up studies. The need for long term follow‐up data has become emerged with concern over late stent thrombosis. Methods: 246 saphenous vein graft patients undergoing stenting from August 2002–December 2008 were studied. Overall survival and event‐free survival were compared by Kaplan‐Meier method. Hazard ratios (HR) were calculated by Cox‐proportional hazards models. Results: We treated 133 patients with DES (median follow‐up four years) and 113 patients with BMS (median follow‐up four years) for SVG stenosis. Overall survival (77.0% ± 3.9% vs. 70.6% ± 4.6%, log‐rank P = 0.60) and MACE‐free survival (57.5% ± 4.6% vs. 56.8% ± 4.9, log‐rank P = 0.70) were not significantly different between the DES and BMS groups. Although BMS was associated with increased risk of target lesion revascularization (TLR) (freedom from TLR 85.2% ± 3.5% vs. 90.0% ± 3.0%, HR 2.07, 95% CI 0.97–4.42, log‐rank P = 0.05), there was no significant difference in the freedom from myocardial infarction (86.7% ± 3.3% vs. 88.7% ± 3.2%, log‐rank P = 0.39) or target vessel revascularization (77.1% ± 4.2% vs. 76.1% ± 4.2%, log‐rank P = 0.33) between the two groups. Conclusions: Although mortality is not statistically different between DES and BMS for SVG stenosis, BMS is associated with increased risk of revascularization, thus suggesting the superiority of DES over BMS in the long term.
