Left Ventricular End‐Diastolic Pressure in Anginal Patients: Lack of Correlation with New York Heart Association's Functional Classification

The New York Heart Association (NYHA) recently designated functional classifications I, II, and III for angina. In the authors' series of 80 male anginal patients, observations were made on the mean left ventricular end‐diastolic pressure (LVEDP) at rest and after left ventriculography, and on the percentage of anginal patients with an abnormal LVEDP under these respective circumstances. The findings indicated no significant differences on the basis of NYHA classifications I, II, and III. In the authors' opinion, the NYHA functional classification cannot be used to distinguish the presence or absence of abnormal left ventricular function in Class I, II, and III anginal patients.
