Left ventricular function during pregnancy.
As emphasized by Watkins et al.,9 the variability in plasma renin activity in CHF is explained by the degree of compensation in maintaining arterial pressure and plasma volume; the latter measurement was not obtained in the Curtiss or Gavras study. The observations in these two recent studies reaffirm the importance of the RAA system in maintaining systemic vascular resistance (SVR) in CHF. Cur...
متن کاملMaternal left ventricular mass and diastolic function during pregnancy.
OBJECTIVE To evaluate changes in left ventricular mass and diastolic function during normal pregnancy. METHODS This was a cross-sectional study of 125 pregnant women at 9-42 weeks of gestation and 19 non-pregnant female controls. Two-dimensional and M-mode echocardiography of the maternal left ventricle and left atrium was performed. RESULTS During pregnancy left ventricular mass increased ...
متن کاملLeft ventricular function during sudden strenuous exercise.
Strenuous exercise without warm-up has been shown to produce ischemia-like electrocardiographic (ECG) abnormalities in 60-70% of healthy subjects. These abnormalities appeared to be related to the development of an unfavorable myocardial supply/demand balance and, in chronically instrumented dogs, to transient decreases in coronary blood flow. A mechanism involving subendocardial ischemia has b...
متن کاملLeft ventricular function during and after right ventricular pacing.
OBJECTIVES The aim of this research was to evaluate right ventricular pacing effects on left ventricular function. BACKGROUND Right ventricular pacing alters the ventricular activation sequence and reduces left ventricular ejection fraction (EF). It is unclear whether the observed reduction in EF can be completely attributed to the alteration in activation sequence. METHODS Twelve subjects ...
متن کاملLeft ventricular diastolic function in normal human pregnancy.
BACKGROUND Little information is available about changes in left ventricular diastolic function during pregnancy. We used mitral inflow and pulmonary venous flow profiles to evaluate left ventricular diastolic function in 37 healthy pregnant women 26 to 41 years old (mean, 32 years). METHODS AND RESULTS Echocardiographic studies were performed at the end of each trimester. Eight subjects (con...
