Background: The RALES trial demonstrated that spironolactone improved the prognosis of patients with heart failure (HF). However, it is unknown whether the discharge use of spironolactone is associated with better long-term outcomes among hospitalized systolic HF patients in routine clinical practice. We examined the effects of spironolactone use at discharge on mortality and rehospitalization by comparing with outcomes in patients who did not receive spironolactone.

However, in heart failure (HF), elevated body mass index (BMI) has been shown to be associated with better prognosis, but it is unknown whether this is the case in unselected HF patients encountered in routine clinical practice in Japan.
Methods And Results: The Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) studied prospectively the characteristics and treatments in a broad sample of patients hospitalized with worsening HF and the outcomes were followed for 2.
Background: Hyperuricemia is associated with worse outcomes of patients with chronic heart failure (HF). However, it is unknown in an unselected HF patients encountered in routine clinical practice. We thus assessed the impact of hyperuricemia on long-term outcomes including mortality and rehospitalization among patients hospitalized with worsening HF.

However, it is unknown whether this therapeutic approach can also improve the long-term survival. We thus examined the long-term effects of beta-blocker use at discharge on outcomes in patients hospitalized for HF and left ventricular systolic dysfunction (LVSD) (ejection fraction <40%).

Large-scale, placebo-controlled, randomized clinical trials have shown that angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) reduce mortality and hospitalization in patients with heart failure (HF) caused by left ventricular systolic dysfunction (LVSD). However, it is unknown whether ACE inhibitors and ARBs have similar effects on the long-term outcomes in HF patients encountered in routine clinical practice. The Japanese Cardiac Registry of Heart Failure in Cardiology enrolled HF patients hospitalized with worsening symptoms and they were followed during an average of 2.

Objective: We aimed to clarify the relationships between diastolic strain rates and global diastolic function and find a useful index for regional diastolic function in patients with hypertrophic cardiomyopathy (HCM).
Methods: Strain rate curves were obtained using an apical approach at 12 different sites of the left ventricular myocardium in 25 patients with HCM and 20 control subjects, and peak early diastolic strain rate (ESR), peak late diastolic strain rate, and the time from QRS to ESR were measured.
Objectives: The efficacy of antihypertensive agents can vary in patients. Four to 8 weeks may be required before antihypertensive agents become fully effective. Predicting the efficacy can help agent selection and dose setting.

This study was designed to determine whether increased plasma concentrations of N-terminal pro-brain natriuretic peptide sensitively reflect abnormal diastolic function associated with hypertension.
Methods: Concentrations of N-terminal pro-brain natriuretic peptide in plasma were assayed in 40 previously untreated hypertensive patients without overt congestive heart failure and in 20 age and sex-matched controls.
Background: Myocardial viability is not synonymous with contractile reserve and identifiable in a significant percentage of dysfunctional myocardial segments without contractile reserve. The usefulness of ultrasonic tissue characterization by the phase-corrected magnitude of cyclic variation of integrated backscatter (MVIB) in chronic coronary artery disease is not fully validated. Thus, whether MVIB predominantly reflects the contractile reserve or myocardial viability of chronically dysfunctional myocardium was determined.

We hypothesized that IMT in a peripheral, muscular artery known to be resistant to atherosclerotic changes would increase with hypertension, thereby limiting increases in wall stress and potentially preserving endothelial cell function reflected by flow-mediated dilation (FMD). Plasminogen activator inhibitor type-1 (PAI-1) can inhibit vascular smooth muscle cell migration contributing to increased IMT.
