Isolated papillary muscle rupture with nonobstructive coronary artery disease, minimal myocardial infarction, and normal wall motion.

Papillary muscle (PM) rupture can usually complicate inferior or posterior myocardial infarctions, but selective PM infarction is extremely rare, and the exact underlying pathophysiological mechanism is not entirely clear. We present a case of PM rupture due to isolated PM infarction in a patient with unobstructed coronary arteries, which could be misdiagnosed as a vegetation or other mass given the absence of regional wall motion abnormalities (RWMAs) on transthoracic echocardiogram. Our case highlights that in patients with severe mitral regurgitation and associated mitral valve mass, the absence of RWMAs should not exclude ischemic PM rupture from differential diagnosis.

Short-term effects of angiotensin receptor-neprilysin inhibitors on diastolic strain and tissue doppler parameters in heart failure patients with reduced ejection fraction: A pilot trial.

Objective: Although sacubitril/valsartan has recently shown its long-term benefits on morbidity and mortality in symptomatic patients with chronic heart failure with reduced ejection fraction (HFrEF), its short-term effects on diastolic function remain uncertain. We sought to assess 30-day effects of sacubitril/valsartan on left ventricular (LV) diastolic paremeters determined by speckle tracking and tissue Doppler imaging (STI and TDI respectively) as well as their association with functional capacity change evaluated by peak oxygen uptake (VOmax) in stable patients with symptomatic HFrEF.

Methods: A total of 35 patients (aged 61 ± 9 years) eligible for sacubitril/valsartan underwent a complete two-dimension (2D) echocardiographic study and a cardiopulmonary exercise test at baseline and 30 days after the initiation of therapy.

Troponin-I levels as a potential prognostic biomarker of sacubitril/valsartan treatment response in heart failure with reduced ejection fraction: Who will benefit most?

Background: Despite robust data on the benefits of sacubitril/valsartan (LCZ696) in patients with chronic heart failure with reduced ejection fraction (HFrEF), there is no evidence yet on prespecified predictive markers of its efficacy. Hypothesis The objective of this study was to identify potential prognostic factors of LCZ696 treatment response.

Methods: We included 48 symptomatic patients with chronic HFrEF (left ventricular ejection fraction ≤35%) and New York Heart Association (NYHA) class II/III: Group A (N = 23) received LCZ696 (105 ± 30 mg twice daily), whereas it was not prescribed in group B (N = 25) according to physician's judgment.

Cardiac resynchronization therapy (CRT) device replacement considerations: upgrade or downgrade? A complex decision in the current clinical setting.

There are limited data about the management of patients presenting for elective generator replacements in the setting of previously implanted cardiac resynchronization therapy (CRT) devices that are nearing end-of-life. The individual patient's clinical status and concomitant morbidities may evolve so that considerations may include not only replacement of the pulse generator, but also potentially changing the type of device [e.g.

Alterations in the expression of genes related to contractile function and hypertrophy of the left ventricle in chronically paced patients from the right ventricular apex.

Aim: Long-term right ventricular apical (RVA) pacing may lead to left ventricular (LV) remodelling and heart failure. This study assessed changes in the expression of genes regulating LV contractile function and hypertrophy, after permanent RVA pacing and investigated whether such changes proceed or even predict LV remodelling.

Methods And Results: We enrolled 52 consecutive patients (age 79.

New therapeutic options in heart failure. What's on the horizon? An overview.

Heart failure is a complex clinical syndrome responsible for high morbidity and mortality in the world. Despite advances in the management of heart failure, the prognosis of these patients remains poor and there is a critical need for new treatment strategies improving the clinical outcomes. New approaches in heart failure therapies target cellular mechanisms, as well as mechanical and structural aspects of heart failure that are not addressed by recent therapies.

Efficacy and safety of ezetimibe plus orlistat or rimonabant in statin-intolerant nondiabetic overweight/obese patients with dyslipidemia.

Aims: To compare the effects of ezetimibe plus orlistat or rimonabant on anthropometric and lipid parameters in nondiabetic statin-intolerant overweight/obese patients with dyslipidemia.

Methods And Results: Thirty participants received a hypocaloric diet and were randomized to open-label combination of ezetimibe (10 mg/day) with orlistat (120 mg, 3 times a day with meals; ezetimibe/orlistat [EO], n = 15) or rimonabant (20 mg/day; ezetimibe/rimonabant [ER], n = 15). Anthropometric and metabolic variables were assessed at baseline and 3 months posttreatment.

The role of C-reactive protein in atherosclerotic cardiovascular disease: an overview.

C-reactive protein (CRP) is an acute-phase protein, which has been used in clinical practice as a non specific marker of inflammation. Many studies have shown that CRP is associated with atherosclerotic cardiovascular disease. It is currently unknown if CRP plays an active role as an etiologic factor in cardiovascular disease.

Orlistat-associated adverse effects and drug interactions: a critical review.

Orlistat, an anti-obesity drug, is a potent and specific inhibitor of intestinal lipases. In light of the recent US FDA approval of the over-the-counter sale of orlistat (60 mg three times daily), clinicians need to be aware that its use may be associated with less well known, but sometimes clinically relevant, adverse effects. More specifically, the use of orlistat has been associated with several mild-to-moderate gastrointestinal adverse effects, such as oily stools, diarrhoea, abdominal pain and faecal spotting.

A 12-week, prospective, open-label analysis of the effect of rosuvastatin on triglyceride-rich lipoprotein metabolism in patients with primary dyslipidemia.

Background: Although the effect of statins on lowering low-density lipoprotein cholesterol (LDL-C) has been extensively studied, their hypotriglyceridemic capacity is not fully understood.

Objective: The present study examined clinical and laboratory factors potentially associated with the triglyceride (TG)-lowering effect of rosuvastatin.

Methods: Eligible patients had primary dyslipidemia and a moderate risk of heart disease.
