Aims Left ventricular hypertrophy, obesity, hypertension, and N‐terminal B‐type natriuretic peptide (Nt‐proBNP) predict left ventricular diastolic dysfunction with preserved systolic function (DD‐PSF). Self‐rated health (SRH) is shown to be associated with chronic diseases, but the association of SRH with DD‐PSF is unclear. In light of the clinical implications of DD‐PSF, the following goals are of considerable importance: (1) to determine the role of SRH in patients with DD‐PSF in the general population and (2) to study the association between Nt‐proBNP and DD‐PSF. Methods and results The current study is a cross‐sectional study conducted on a random sampling of a rural population. Individuals 30–75 years of age were consecutively subjected to conventional echocardiography and tissue velocity imaging. Data were collected on 500 (48%) men and 538 (52%) women ( n = 1038). DD‐PSF was the main outcome, and SRH and Nt‐proBNP were the primary indicators. Diabetes mellitus, hypertension, and obesity were accounted for as major confounders of the association with SRH. DD‐PSF was identified in 137 individuals, namely, 79 men (15.8%) and 58 women (10.8%). In a multivariate regression model, SRH (OR 2.95; 95% CI 1.02–8.57) and Nt‐proBNP (quartile 4 vs. quartile 1 OR 4.23; 95% CI 1.74–10.26) were both independently associated with DD‐PSF. Conclusions SRH, evaluated based on a descriptive question on general health, should be included in the diagnostic process of DD‐PSF. In agreement with previous studies, our study confirms that Nt‐proBNP is a major indicator of DD‐PSF.
