Determination of the natural history of aspirin resistance among stable patients with cardiovascular disease.

measured in every patient with heart failure. The advent of tissue Doppler (and other echo-Doppler techniques) has made it easier and more practical to identify abnormalities in diastolic function. Nonetheless, precise and comprehensive assessment of diastolic function requires the use of invasive catheterization techniques. However, if noncardiac and other cardiac causes of heart failure are excluded, the remaining patients with heart failure and a normal EF all have abnormalities of diastolic function making measurement of diastolic function confirmatory rather than a mandatory component of diagnostic criteria. Finally, I join Dr. Kessler in his enthusiastic use of the term “diastolic heart failure” and renew my editorial plea: “Stop the discrimination against the term diastolic heart failure.”
