Left ventricular (LV) properties in hypertension (HTN) could be deteriorated by pressure overload, especially in endocardium, resulting in hypertensive heart failure (HHF). We sought to noninvasively examine LV systolic and diastolic functions at three myocardial layers in HTN and elucidate features of HHF by speckle-tracking echocardiography (STE) with high volume rates. We examined normotensive controls (n = 54), HTN patients without LV hypertrophy (LVH) (n = 50), and HTN patients with LVH (n = 40) and HHF patients (n = 45)...

A growing body of evidence suggests that exercise pulmonary hypertension (ePH) is an early form of pulmonary arterial hypertension (PAH). Identifying the disease at an early, potentially more responsive phase, and initiating treatment may improve functional status and prevent progression to severe forms of PAH. This was a single-center, open-label six-month treatment trial to evaluate the effect of ambrisentan on pulmonary hemodynamics and exercise capacity in ePH utilizing invasive cardiopulmonary exercise testing (iCPET)...

BACKGROUND: Revascularization therapy relieves myocardial ischemia, but can also result in ischemia-reperfusion injury caused by oxidative stress. However, the biokinetics of oxidative stress after myocardial ischemia-reperfusion are uncertain. This study aimed to evaluate the dynamics of oxidative stress after off-pump coronary artery bypass grafting (OPCAB) by measuring urinary biopyrrin levels. Biopyrrin is an oxidative metabolite of bilirubin thought to reflect oxidative stress, along with reactive nitrogen species (RNS)...

BACKGROUND: Rheumatic heart disease is a common reason for cardiovascular morbidity and mortality. Plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) are known to rise in patients with MS, but the role of this compound as a non-invasive marker of left atrial (LA) dysfunction is yet to be established. The study aim was to correlate levels of NT-proBNP in patients with rheumatic mitral stenosis (MS), with echocardiographic parameters of LA function including tissue Doppler-derived strain/strain rate (S/Sr) indices, hemodynamic parameters of LA function, before and after percutaneous balloon mitral valvotomy (PBMV) for a follow up of one year...

BACKGROUND: Diagnosis of heart failure with preserved ejection fraction (HFpEF) is challenging and relies largely on demonstration of elevated cardiac filling pressures (pulmonary capillary wedge pressure). Current guidelines recommend use of natriuretic peptides (N-terminal pro-B type natriuretic peptide) and rest/exercise echocardiography (E/e' ratio) to make this determination. Data to support this practice are conflicting. METHODS: Simultaneous echocardiographic-catheterization studies were prospectively conducted at rest and during exercise in subjects with invasively proven HFpEF (n=50) and participants with dyspnea but no identifiable cardiac pathology (n=24)...
