Why the study?
Does the sequence and magnitude of ventricular volume changes differ between painful and painless myocardial ischemia in patients with angina at rest?
Does the sequence and magnitude of ventricular volume changes differ between painful and painless myocardial ischemia in patients with angina at rest?
Acute left ventricular dilatation occurs consistently during both painful and painless myocardial ischemia, suggesting that the rate and extent of dilatation do not directly cause anginal pain.
No takes yet. Share an insight, caveat, or question.
LV dilatation magnitude does not differentiate painful from silent ischemia; leaves open mechanisms of anginal pain.
Davies et al. (1988) studied this question.
