Nitrates decrease myocardial oxygen consumption by all of the following mechanisms except -
High-Yield Explanation
Ans. is 'a' i.e., By increasing the left ventricular end diastolic pressure o Nitratets dilate veins (capacitance) vessels and decrease venous return (preload)o This results in decreased end diastolic pressure and left ventricular size (not increased), which ultimately leads to decreased oxygen consumption.
