Following an attack of myocardial infarction the moality and morbidity of the patient is indicated by
Answer is B (Left ventricular ejection fraction) Pump failure is now the primary cause of in hospital death following MI. The degree of pump failure relates well with moality. The most sensitive index of cardiac function amongst the options provided is 'ejection fraction' i.e. the ratio of stroke volume to end diastolic volume. This is thus the best indicator of moality & morbidity following ML
Ventricular extra systole
Left ventricular ejection fraction
Duration of syncope
Percentage of narrowness of coronary aery
