Apelin ia a novel multifunction peptide implicated in cardiovascular performance regulation in chronic pressure overload. Plasma apelin level and its correlation to diastolic dysfunction in patient heart failure with preserved ejection fraction were investigated. Hypertensive patients with heart failure but without coronary artery disease, atrial fibrillation, obese, and diabetes mellitus were enrolled in this study. Each patients underwent plasma apelin measurement and echocardiographic assessment of left ventricular diastolic function. Statistical analysis was conducted using Spearman Rank. Fifty patients, 24 males (48%) and 26 females (52%), met the inclusion criteria. The mean age of the participants was 58.72 (11.02) years with a duration of hypertension between 1–30 years, median 5 year. Mean body mass index was 24.13 kg/m2. Systolic blood pressure median was 130 (120–180)mmHg while the diastolic blood pressure median was 90 (70–110)mmHg. Left ventricular ejection fraction median was 65 (49–77)%, treatment with Angiotensin converting enzyme inhibitor (ACEI) was 48%, calcium channel blocker (CCB) was 27%, beta blocker was 6%, angiotensin receptor blocker (ARB) was 3%, and diuretic was 1%. Diastolic function assessment with tissue doppler imaging (TDI) resulted in a mean of 10.32, deceleration time mean of 228.2, E/A (early/atrial (late) filling velocities) ratio median of 0.77 (0.43–1.53),and IVRT (isovolumic relaxation time) median of 92 (59–177). Plasma apelin measurement median was 1080.5 (993.2–11) pg/mL. In conclusion, there is a positive correlation between plasma apelin level and diastolic function (TDI) (R=0.3445, p=0.014). There is no significant correlation between plasma apelin level and diastolic function using other criteria. In conclusion, apelin can be used for assessing symptoms and prognosis of heart failure patients with preserved ejection fraction because apelin level is upregulated when pressure overload occurs with less fibrosis and down-regulated when pressure overload occurs with marked fibrosis.
