| Popis: | One hundred and seventy-two patients (110 were greater than or equal to 65 years and 62 were less than 65 years) with congestive heart failure (CHF) were prospectively evaluated to determine various pathophysiologic mechanisms of CHF. The incidence of CHF with normal left ventricular (LV) systolic function was higher in elderly (30% vs 12%, p less than 0.05). Of the 110 elderly patients, LV systolic function was impaired in 77. Fifty-five patients had LV dilatation without increased wall thickness, and the clinical diagnosis was "dilated cardiomyopathy in the elderly". Twenty-two patients had hypertrophied LV and a high incidence of hypertension, and they were diagnosed as "hypertensive heart failure" due to contractile dysfunction. On the contrary, the remaining 33 patients did not have impaired LV contractile function. Thirteen patients lacking LV hypertrophy had enlarged atria. CHF was induced by reduced chamber compliance called "the stiff heart syndrome". Twenty patients had hypertrophied LV and a high incidence of hypertension. They were diagnosed as having "hypertensive hypertrophic cardiomyopathy of the elderly" and abnormalities of diastolic function accounted for the CHF. Since echocardiography can easily and accurately diagnose the pathophysiologic mechanism of CHF, an increased awareness of its occurrence in the elderly and use of echocardiography would reduce diagnostic and therapeutic errors. |
