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