Prevalence of symptomatic diastolic heart failure in patients hospitalized with cerebral or peripheral vascular disease

The authors sought to determine the prevalence of diastolic heart failure (DHF) in patients hospitalized with their first stroke, transient ischemic attack, or new onset of peripheral vascular disease. A total of 216 prospective consecutive stroke, transient ischemic attack, and peripheral vascular disease patients (vascular group) were identified at their first noncardiac presentation to a hospital and compared with 164 age-matched control patients (nonvascular group). DHF was clinically defined as the presence of left ventricular ejection fraction>or=45% on echocardiography. DHF occurred in 40% and 73% of vascular and control patients, respectively, with symptomatic heart failure. Overall, it was found in 12% of vascular (10% of stroke/transient ischemic attack, 16% of peripheral vascular disease) and 11% of control patients. Advancing age and female gender were independently associated with the presence of DHF in vascular patients (p<0.05). DHF is found in a similar percentage of vascular and nonvascular patients. Symptomatic DHF is less common than systolic heart failure among vascular disease patients with heart failure. In contrast, symptomatic DHF is found in three times as many age-matched control heart failure patients without clinical vascular disease.
