It has been elucidated that mineralocorticoid receptor antagonists reduce mortality in patients with congestive heart failure and post-acute myocardial infarction. A direct inhibition of aldosterone synthase (CYP11B2) is also expected to have therapeutic benefits equal in quality to mineralocorticoid receptor antagonists in terms of reducing mineralocorticoid receptor signaling. Therefore, we have screened our chemical libraries and identified a novel and potent aldosterone synthase inhibitor, 2,2,2-trifluoro-1-{4-[(4-fluorophenyl)amino]pyrimidin-5-y}-1-[1-(methylsulfonyl)piperidin-4-yl]ethanol (compound 1), by lead optimization...

BACKGROUND: The presence and implications of abnormal arterial stiffness, a potential independent predictor of outcomes, in community-dwelling treated hypertensives is unknown. Furthermore, limited data exist regarding the risk of cardiovascular disease (CVD) associated with arterial stiffness across the entire range of blood pressure. METHODS AND RESULTS: We measured carotid-femoral pulse wave velocity (PWV) and classical CVD risk factors in 2127 community-dwelling participants (mean age 60 years, 57% women) of The Framingham Offspring Cohort...

Many animal models have been established for the study of myocardial remodeling and heart failure due to its status as the number one cause of mortality worldwide. In humans, a pathologic occlusion forms in a coronary artery and reperfusion of that occluded artery is considered essential to maintain viability of the myocardium at risk. Although essential for myocardial recovery, reperfusion of the ischemic myocardium creates its own tissue injury. The physiologic response and healing of an ischemia/reperfusion injury is different from a chronic occlusion injury...

Direct reprogramming of fibroblasts into induced cardiomyocytes (iCMs) holds great promise as a novel therapy for the treatment of heart failure, a common and morbid disease that is usually caused by irreversible loss of functional cardiomyocytes (CMs). Recently, we and others showed that in a murine model of acute myocardial infarction, delivery of three transcription factors, Gata4, Mef2c, and Tbx5 converted endogenous cardiac fibroblasts into functional iCMs. These iCMs integrated electrically and mechanically with surrounding myocardium, resulting in a reduction in scar size and an improvement in heart function...

There have been few reports about ratchet syndrome. We report a case of ratchet syndrome caused by small hair-pin curve of lead that triggered the lead retract itself. A 69-year-old man with a past history of inferior wall myocardial infarction, presented with progressive congestive heart failure. He underwent implantation of cardiac resynchronization therapy with an implantable cardiac defibrillator (CRTD) at our hospital. At 33 days after implantation, shock lead dislodgement was revealed. X-ray showed that the lead tip was in left subclavian vein, leaving its screw out, and a large part of the proximal portion of the lead was retracted into the pocket, while the other two leads remained in appropriate positions and the device had not rotated...

BACKGROUND: Remote ischemic conditioning (RIC) has been shown to be a practical method for protecting the heart from ischemic/reperfusion (I/R) injury. In the present study, we investigated whether or not the combination of RIC and Astragaloside IV (AS-IV) could improve cardioprotection against acute myocardial infarction (AMI)-induced heart failure (HF) when compared with individual treatments. MATERIAL AND METHODS: A rat model of AMI was established via permanent ligation of the left anterior descending coronary artery (LAD)...

Cell death in MI is the most critical determinant of subsequent left ventricular remodeling and heart failure. Besides apoptosis, autophagy and necroptosis have been recently found to be another two regulated cell death styles. HGF has been reported to have a protective role in MI, but its impact on the three death styles remains unclear. Thus, our study was performed to investigate the distribution of autophagy, apoptosis and necroptosis in cardiac tissues after MI and explore the role and mechanism of Ad-HGF on cardiac remodeling by regulating the three death styles...

Acute heart failure is still characterized by poor prognosis with high mortality. Diagnosis is based on clinical symptoms and hemodynamic measurements. Early coronary revascularization in cardiogenic shock complicating myocardial infarction improves outcome. The further contemporary therapeutic options in the management of acute heart failure are limited to a merely symptomatic effect with relief of dyspnea, reduction of volume overload and improvement of hemodynamic parameters by vasodilators (in hypertension) or inotropic and vasopressor agents (in hypotension)...

The benefit of beta blockers to patients with heart failure is undisputed. However, most trials of their benefits after acute myocardial infarction were carried out decades ago, when reperfusion therapy was not undertaken and secondary prevention drugs, such as statins, were unavailable.

BACKGROUND: Global iodine-123 metaiodobenzylguanidine (I-MIBG) uptake is predictive of cardiovascular events and mortality in patients with heart failure. Normal variations in global and regional uptake, however, are not well defined and few studies have addressed the functional relevance of I-MIBG uptake and distribution in healthy individuals. MATERIALS AND METHODS: We performed I-MIBG scintigraphy and cardiac autonomic function testing using the standardized methodology in 15 healthy individuals (mean age 54...

OBJECTIVE: Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for pain and inflammation. NSAIDs are associated with serious adverse effects and cardiovascular (CV) risks that include myocardial infarction, stroke and heart failure. In the period of time immediately after a CV event, modification to the drug therapy regimen and lifestyle habits should be instituted to decrease morbidity and mortality. The objective of this study is to measure the prevalence of NSAIDs prescribing in the immediate 90 days after a CV-related hospitalization in Medicaid beneficiaries in Puerto Rico...

Reduction of preventable hospital readmissions that result from chronic or acute conditions like stroke, heart failure, myocardial infarction and pneumonia remains a significant challenge for improving the outcomes and decreasing the cost of healthcare delivery in the United States. Patient readmission rates are relatively high for conditions like heart failure (HF) despite the implementation of high-quality healthcare delivery operation guidelines created by regulatory authorities. Multiple predictive models are currently available to evaluate potential 30-day readmission rates of patients...

OBJECTIVES: To examine whether the CADILLAC risk score is an effective method of patient stratification for early discharge following ST elevation myocardial infarction (STEMI). BACKGROUND: Patients with STEMI are typically hospitalized to monitor for serious complications such as arrhythmias, heart failure, and reinfarction. Optimal length of stay is unclear. Whether low risk patients can be safely discharged before 72 hr of hospitalization is unclear. METHODS: Patients with STEMI who underwent successful PCI were retrospectively stratified using CADILLAC risk score to low risk (n = 123) and intermediate to high risk (n = 105)...

Hypertension is an important risk factor for premature death as it increases the probability of stroke, myocardial infarction, and heart failure. Antihypertensive drugs can decrease cardiovascular (CV) morbidity and mortality. The majority of hypertensive patients need more than one antihypertensive agent to attain blood pressure (BP) targets. Monotherapy can effectively reduce BP only in 20%-40% of patients. Multiple mechanisms including increased peripheral vascular resistance, increased cardiac work, and hypervolemia are involved in the pathogenesis of hypertension...

: Myocardial infarction is one of the leading causes of cardiac dysfunction, failure and sudden death. Post infarction cardiac remodeling presents a poor prognosis, with 30%-45% of patients developing heart failure, in a period of 5-25years. Oxidative stress has been labelled as the primary causative factor for cardiac damage during infarction, however, the impact it may have during the process of post infarction remodeling has not been well probed. In this study, we have implemented iTRAQ proteomics to catalogue proteins and functional processes, participating both temporally (early and late phases) and spatially (infarct and remote zones), during post myocardial infarction remodeling of the heart as functions of the differential oxidative stress manifest during the remodeling process...
