Left ventricular hypercontractility in hypertensive patients
with anginal pain and normal coronary angiograms
Zeitschrift fur Kardiologie
(Aug) 84:606-613 1995
Wehling et al found that up to 30% of hypertensive patients undergoing
angiography for angina or exercise-induced ST depression had normal coronary
arteries. They compared LV volumes and ejection fractions in 50 patients
with hypertension and 50 normotensive controls with no coronary artery
Hypertensive patients had reduced end-diastolic volume and increased ejection
fraction. End diastolic volumes were similar in hypertensives and controls.
They theorize that LV hypercontractility and an increase in oxygen
consumption might explain anginal symptoms in hypertensive patients with
normal coronary angiograms.
