Insights
Calcific aortic valve disease (CAVD) risk factors in Afghans include sedentary lifestyle, diabetes mellitus, high BMI, good socioeconomic status, and hypertension. These factors are linked to CAVD development, not just aging.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Calcific aortic valve disease (CAVD) is increasingly recognized as a significant health issue.
- While aging is a known factor, specific risk factors for CAVD are not fully understood, particularly in diverse populations.
- Previous research indicates CAVD may be influenced by specific risk factors beyond aging.
Purpose of the Study:
- To identify the clinical features of CAVD in the Afghan population.
- To determine independent risk factors associated with CAVD in this demographic.
- To contribute to a better understanding of CAVD epidemiology in South Asia.
Main Methods:
- A case-control study involving 1072 Afghan participants (age >18 years) was conducted from January 2018 to December 2020.
- Participants were categorized into two groups: 536 with CAVD and 536 age- and sex-matched controls, based on echocardiographic findings.
- Multivariate logistic regression analysis was employed to identify independent predictors of CAVD using data from medical records and questionnaires.
Main Results:
- The study identified several independent risk factors for CAVD in the Afghan population.
- These include a sedentary lifestyle (OR=2.517), diabetes mellitus (OR=1.902), high body mass index (BMI ≥ 30 kg/m²; OR=1.776), good socioeconomic status (OR=1.724), and hypertension (OR=1.664).
- Aortic valve stenosis, aortic valve calcification, and bicuspid aortic valve were observed among CAVD patients.
Conclusions:
- Sedentary lifestyle, diabetes mellitus, high BMI, good socioeconomic status, and hypertension are significant independent risk factors for CAVD in the Afghan population.
- These findings suggest that CAVD is not solely an age-related condition and can be influenced by modifiable lifestyle and health factors.
- The study highlights the need for targeted interventions and awareness programs for CAVD prevention in this population.
Objective:
Evidence from previous studies suggests that calcific aortic valve disease (CAVD) is not an unavoidable consequence of aging, and may be linked to explicit risk factors. However, little is known regarding the Afghan population in this context. The current study aimed to identify the clinical features of CAVD and determine independent risk factors for CAVD in the Afghan population.
Patients And Methods:
A case-control study was conducted among 1072 Afghan participants (age >18 years) from January 2018 to December 2020. The study participants were divided into two groups based on echocardiographic findings: 536 individuals with CAVD and 536 age- and sex-matched controls. Data were collected using questionnaires from the medical records of all cases and controls. The independent predictors of CAVD were evaluated using multivariate logistic regression analysis.
Results:
The mean age of study participants was 65.3 ± 13.5 years (range, 20-100 years). Of the 536 patients with CAVD, 77 (14.4%) had aortic valve stenosis, 415 (77.4%) had aortic valve calcification, and 44 (8.2%) had bicuspid aortic valve. Multivariate logistic regression analysis revealed that sedentary lifestyle (odds ratio [OR] = 2.517, p = 003), diabetes mellitus (DM) (OR = 1.902, p = 006), high body mass index (BMI ≥ 30 kg/m2) (OR = 1.776, p = 005), good socioeconomic status (OR = 1.724, p = 021), and hypertension (OR = 1.664, p ˂0.001) were independent risk factors for CAVD in the Afghan population.
Conclusion:
It was observed that sedentary lifestyle, diabetes mellitus, high BMI (≥ 30 kg/m2), good socioeconomic status, and hypertension are independent risk factors for the development of CAVD compared to those with a normal aortic valve in the Afghan population.
