Key result
Age 60 years and older (aOR 6.1) and dyslipidemia (aOR 3.45) were significantly associated with an increased risk of left ventricular diastolic dysfunction in patients with hypertension.
Why the study?
The study was conducted to determine the prevalence and correlates of diastolic dysfunction in hypertensive patients living in Saudi Arabia.

Left ventricular diastolic dysfunction is highly prevalent (35.6%) among hypertensive patients in Saudi Arabia, with advanced age and dyslipidemia identified as significant independent correlates.
Highlights a high burden of subclinical heart failure in older, dyslipidemic.
INTRODUCTION: diastolic dysfunction refers to impaired ventricular relaxation or filling regardless of ejection fraction and symptoms. It accounts for 8% and 25% in the hospitalized and general population, respectively. The present study was conducted to determine the prevalence and correlates of diastolic dysfunction in hypertensive patients living in Saudi Arabia. METHODS: a multicentric, cross-sectional study was conducted from February 2019 to February 2020 at King Khalid Hospital and Prince Sultan Center for Health Services, Prince Sattam Bin Abdulaziz University hospital in Al Kharj, and Al Kharj Military Industries Corporation hospital, KSA. All patients with hypertension who underwent an echocardiography were included in the study. Logistic regression analysis was performed to determine factors associated with left ventricular diastolic dysfunction (LVDD). RESULTS: the study included a total of 104 participants, where 51.9% were females and the mean age of the patients was 48.01±12.81 years. Most patients had an abnormal echocardiography finding (64.4%, n = 67). The most common abnormalities were left ventricular (LV) hypertrophy (44.2%, n = 46), and diastolic dysfunction, (35.6%, n = 37). The study revealed that age (aOR: 6.1, 95% CI 1.17-31.3; p = 0.032) and dyslipidemia (aOR: 3.45, 95% CI 1.16-10.24; p = 0.026) have significant association with LVDD in the patients with hypertension. CONCLUSION: in conclusion, diastolic dysfunction is prevalent among older hypertensive patients and those with dyslipidaemia. Age and dyslipidaemia were non-modifiable and modifiable factors associated with LVDD in hypertensive patients, respectively.

Al‐Ghamdi et al. (2021) conducted a cross-sectional in Hypertension (n=104). Age ≥60 years vs. Age <40 years was evaluated on Left ventricular diastolic dysfunction (LVDD) (aOR 6.1, 95% CI 1.17-31.3, p=0.032). Age 60 years and older (aOR 6.1) and dyslipidemia (aOR 3.45) were significantly associated with an increased risk of left ventricular diastolic dysfunction in patients with hypertension.
