Abstract:

Objective

To explore the predictive value of CHA2DS2-VASc or the risk of stroke in patients with hypertension and coronary heart disease (CHD).

Methods

Among the 3555 patients diagnosed with hypertension and coronary heart disease admitted to Xuzhou Central Hospital and the Affiliated Hospital of Xuzhou Medical University from March 2019 to December 2020, the CHA2DS2-VASc score was calculated based on their clinical baseline data. Interactions between blood pressure level and risk factors of stroke were assessed using Logistic regression model. The area under the curve (AUC) of the receiver operating characteristic was used to determine the predictive value of CHA2DS2-VASc score for stroke in patients with hypertension and CHD.

Results

The higher blood pressure was association with increased age, proportion of women and prevalence of complications, such as diabetes, heart failure, stroke/transient ischemic attack, vascular disease and atrial fibrillation classification (P<0.05). CHA2DS2-VASc score was positively correlated with blood pressure and NYHA functional classification (P<0.05). Men, patients with diabetes or heart failure, and CHA2DS2-VASc score≥5 were more likely to develop stroke (P<0.05). The AUC of stroke risk perdicted with CHA2DS2-VASc score was 0.923 (95%CI: 0.910-0.936, P<0.001) in 3555 patients with hypertension and CHD, among which, AUC was 0.938 (95%CI: 0.926-0.951, P<0.001) in 2603 male patients and 0.921 (95%CI: 0.898-0.945, P<0.001) in 952 female patients.

Conclusion

The CHA2DS2-VASc score has excellent predictive value for stroke risk in patients with hypertension and combined with CHD. There are sex differences in the predictive value of the CHA2DS2-VASc score due to the diversity and complexity of stroke risk factors in female patients.
