Factors that limit exercise tolerance in severe mitral stenosis

Factors That Influence Exercise Tolerance

Due to the improvements in medical care, individuals with spinal cord injury (SCI) are now mirroring the nondisabled population in life expectancy and cause of death . In a study by Geisler and Jousse (1), renal (kidney) failure remained the leading cause of death, at 30.8 percent of the population with SCI studied . A 1983 study on the survival rates of individuals with SCI done by Geisler, sh...

Severe congenital mitral stenosis in infants.

BACKGROUND Despite current medical and surgical therapy, infants with symptomatic congenital mitral stenosis (CMS) continue to have high rates of morbidity and mortality. Catheter balloon dilation has been successful in relieving symptoms in a few older children with CMS but has not been evaluated in infants. METHODS AND RESULTS We reviewed the records of 85 infants with CMS to assess severit...

Failure of propranolol to improve exercise tolerance in patients with mitral stenosis in sinus rhythm.

Propranolol reduces left atrial pressure at rest and during exercise in patients with mitral stenosis by lowering cardiac output and heart rate. Ten patients (aged 19-56) with moderate to severe isolated mitral stenosis were studied to determine whether propranolol increased their exercise tolerance. All were in sinus rhythm and free of left or right ventricular failure. Patients were trained i...
