Insights
Japanese men with multiple combined cardiovascular risk factors face significantly higher risks of coronary heart disease (CHD) and stroke mortality. Identifying and managing this high-risk group is crucial for improving health outcomes.
Area of Science:
- Cardiovascular epidemiology
- Public health
- Preventive medicine
Background:
- Combined cardiovascular risk factors pose a significant health concern.
- Understanding their prognostic significance in diverse populations is essential.
Purpose of the Study:
- To investigate the prognostic impact of combined cardiovascular risk factors on coronary heart disease (CHD) and stroke mortality in the Japanese population.
- To analyze the relationship between a high-risk group defined by combined factors and mortality outcomes.
Main Methods:
- Analysis of the NIPPON DATA80 database, following 4,144 men and 5,318 women for 14 years.
- Defined risk factors: hypertension, hypercholesterolemia, hyperglycemia, and obesity.
- Categorized subjects into risk groups (0, 1-2, and 3-4 combined risks).
Main Results:
- Men in the high-risk group (3-4 combined factors) showed significantly elevated mortality.
- Hazard ratios for CHD mortality were 8.04 and for stroke mortality were 5.06 compared to the low-risk group.
- No statistically significant differences were observed in women, likely due to fewer events.
Conclusions:
- A high-risk group with combined cardiovascular risk factors is a significant predictor of mortality in Japanese men.
- This highlights the importance of managing multiple risk factors concurrently for preventive cardiovascular care in men.
Background:
To examine the prognostic significance of the high-risk group with combined cardiovascular risk factors in the Japanese, we analyzed the relationship between the high-risk group with combined risks and coronary heart disease (CHD) and stroke mortality using the NIPPON DATA80 database.
Methods And Results:
At baseline in 1980, those of age>or=30 years were randomly selected and 4,144 men and 5,318 women without CHD and/or stroke at baseline were followed for 14 years. The cutoff values for risk components obtained heuristically by Cox analysis were hypertension (systolic>or=130, or diastolic>or=85 mmHg, or on antihypertensive drugs), hypercholesterolemia (total cholesterol>or=200 mg/dl), hyperglycemia (>or=130 mg/dl, or self-reported diabetes) and obesity (body mass index>or=27 kg/m2). Subjects were divided into 3 groups (0, 1-2 and 3-4 risks). Compared with those men in the risk 0 group, the hazard ratios in men in the risk 3-4 for CHD mortality was 8.04 (95% confidence interval: 1.03-62.6), and the stroke mortality was 5.06 (1.53-16.7). In women, no statistically significant difference was found due to a lesser number of events.
Conclusion:
The high-risk group with combined risk factors is important risk for Japanese men.
