OBJECTIVES: This study sought to investigate the effect of different types of exercise on left ventricular (LV) geometry in a large group of female and male athletes. BACKGROUND: Studies assessing cardiac adaptation in female and male athletes indicate that female athletes reveal smaller increases in LV wall thickness and cavity size compared with male athletes. However, data on sex-specific changes in LV geometry in athletes are scarce. METHODS: A total of 1,083 healthy, elite, white athletes (41% female; mean age 21...

OBJECTIVES: This study sought to evaluate mechanisms of effort intolerance in patients with rheumatic mitral stenosis (MS). BACKGROUND: Combined stress echocardiography and cardiopulmonary testing allows assessment of cardiac function, hemodynamics, and oxygen extraction (A-Vo2 difference). METHODS: Using semirecumbent bicycle exercise, 20 patients with rheumatic MS (valve area 1.36 ± 0.4 cm(2)) were compared to 20 control subjects at 4 pre-defined activity stages (rest, unloaded, anaerobic threshold, and peak)...

OBJECTIVES: To clarify the prognostic significance of diagnosing whether the failing heart is functioning on the descending limb of the Starling curve by using echocardiography with passive leg lifting (PLL). BACKGROUND: Patients with advanced heart failure can shift to the descending limb of the Starling curve, in which pre-load does not lead to an expected increase in forward left ventricular stroke volume (LVSV). METHODS: Thirty-five consecutive patients with left ventricular (LV) ejection fraction of <40% underwent echocardiography at rest during baseline and during PLL to increase pre-load...

OBJECTIVES: The aim of this study was to assess the relationship of the extent of atherosclerosis on coronary computed tomographic angiography to the extent of secondhand tobacco smoke (SHTS) exposure in asymptomatic never smokers. BACKGROUND: A dose-related association between SHTS and coronary artery calcium has been reported, but the total extent of atherosclerosis has not been investigated. METHODS: Two hundred sixty-eight never smokers, ages 40 to 80 years, completed a questionnaire assessing risk factors and extent of lifetime SHTS exposure, providing a total SHTS exposure score...

OBJECTIVES: The aim of this study was to describe associations of the presence of lipid-rich necrotic core (LRNC) in the proximal superficial femoral artery (SFA) with lower extremity peripheral artery disease (PAD) event rates and systemic cardiovascular event rates. BACKGROUND: LRNC in the coronary and carotid arteries is associated with adverse outcomes but has not been studied previously in lower extremity arteries. METHODS: Participants with ankle-brachial index (ABI) values <1...

OBJECTIVES: This study sought to compare techniques evaluating cardiac dysautonomia and predicting the risk of death of patients with hereditary transthyretin amyloidosis (mATTR) after liver transplantation (LT). BACKGROUND: mATTR is a multisystemic disease involving mainly the heart and the peripheral nervous system. LT is the reference treatment, and pre-operative detection of high-risk patients is critical. Cardiovascular dysautonomia is commonly encountered in ATTR and may affect patient outcome, although it is not known yet which technique should be used in the field to evaluate it...

OBJECTIVES: This study aims to compare ethnic difference in proximal aortic pulse wave velocity (PWV) and characteristic impedance (Zc). BACKGROUND: Increased aortic stiffness is an independent predictor of target organ damage, incident hypertension, and all-cause mortality. However, previous studies have not directly assessed proximal aortic function in Blacks, the ethnic population with disproportionately high risk for incident hypertension and target organ complications...

OBJECTIVES: In the setting of reperfused acute myocardial infarction (AMI), the authors sought to compare prediction of contractile recovery by infarct extracellular volume (ECV), as measured by T1-mapping cardiac magnetic resonance (CMR), with late gadolinium enhancement (LGE) transmural extent. BACKGROUND: The transmural extent of myocardial infarction as assessed by LGE CMR is a strong predictor of functional recovery, but accuracy of the technique may be reduced in AMI...

OBJECTIVES: The aim of this study was to explore the relationship between temporal changes in coronary plaque volume and the intensity of lipid-lowering treatments, utilizing coronary computed tomography angiography (CTA). BACKGROUND: Coronary CTA has acceptable accuracy in terms of quantitative measurement of plaque volume. Although, coronary CTA is perhaps capable of identifying the differences in plaque volume progression according to the intensity of lipid lowering treatment, to date, few studies have examined this notion...
