Nitrates decrease myocardial oxygen consumption by all of the following mechanisms EXCEPT:
Nitrates decrease the ventricular end diastolic pressure by decreasing end-diastolic ventricular volume they cause venodilation, decreases oxygen consumption by hea and en diastolic pressure They are mainly useful in treating angina. REF.Essentials of Pharmacology KD Tripathi 8th ed.
By increasing the left ventricular end diastolic pressure
By direct reduction of oxygen consumption of myocardial the cell
By dilation of the capacitance vessels
By decreasing the size of hea
