Characteristics of coronary arterial lesions in patients with coronary heart disease and hypertension.

Objective: The aim of this study was to investigate the correlations between risk factors such as hypertension and the complex degrees of coronary arterial lesions (CAL).

Methods: We selected 462 patients with coronary heart disease (CHD) with confirmed the stenosis (≥50 %) in at least one major coronary artery on coronary angiography and divided them into the "CHD with hypertension" group (CHD-HT, n = 306) and the CHD group (n = 156). The characteristics of CAL and the occurrence of 2-year postoperative major adverse cardiac cerebrovascular events (MACCE) in the two groups were observed.

Results: The mean SYNTAX scores (SS) was higher in the CHD-HT group than in the CHD group (P < 0.05). The proportions of complex, calcified, and diffused long lesions in the PCI patients' target vascular lesions, as well as the total MACCE incidence, were significantly higher in the CHD-HT group than in the CHD group (P < 0.05). Logistic multifactor regression analysis showed that age, male sex, hypertension, diabetes, hyperlipidemia, and previous history of myocardial infarction were positively correlated with the SS (P < 0.05).

Conclusions: The patients with CHD-HT exhibited complicated and diffused CAL, and arterial hypertension can be considered as a risk factor for the complexity of coronary lesions in patients with ischemic heart disease.
