Effect of Left Ventricular Diastolic Dysfunction on the Cardiopulmonary Exercise Test in Patients with Cardiovascular Disease

Left ventricular diastolic dysfunction is one of main pathophysiologies of heart failure with preserved ejection fraction (HFpEF)1. HFpEF is seen in around 50% of heart failure cases, is not related to sex, shows high multiple morbidities and a high proportion of non-cardiovascular death, in addition to cardiovascular death2. The high degree of left ventricular diastolic dysfunction in chronic heart failure has been shown to be associated with a poor prognosis3. Left ventricular diastolic dysfunction is also present in heart failure with reduced ejection fraction (HFrEF)4.
