What is the most common cause of heart failure with reduced ejection fraction (HFREF)
What is not a reason for the increase in the prevalence of heart failure
What is the test of choice that will help to rule out heart failure (see description below)?
A 45-year-old with no medical history complains of a decline in functional capacity. Physical examination and ECG are normal. Echocardiography demonstrates a preserved ejection fraction without left ventricular hypertrophy. Normal diastolic indices are present at rest. Stress echo is performed and does not support ischemia.
Which measure does not support the diagnosis of heart failure with a preserved ejection fraction (HFPEF)
