Predictors of Cardiovascular Events in Hypertensive Patients with High Cardiovascular Risk

Abstract

Background and objectives: A long-term therapeutic strategy in hypertensive patients equally depends on measured arterial blood pressure values and total determined cardiovascular risk. The aim of the adequate hypertensive patient treatment is both the reduction in arterial blood pressure and the reduction of all preexisting modifiable risk factors, prevention of target organs damage, and adverse cardiovascular events. The aim of this study was to determine independent predictors of cardiovascular events in patients with hypertension and high cardiovascular (CV) risk, and whether the modifiable risk factors could affect long-term prognosis in the studied population. Materials and Methods: This prospective study included 142 hypertensive patients (65% females), mean age 63.1±8 years, with high CV risk. Each participant was followed for 6.2 years. Results: During the follow-up period, the incidence of non-fatal and fatal CV events was 19.7%, CV mortality 7%, and total mortality 9.9%. Our multivariate analysis showed that plaques in both carotid arteries (p = 0.042), diabetes mellitus (p = 0.042) and cholesterol at the beginning of the study (p = 0.016) were significantly associated with an increased risk of CV events. Patients’ age (p = 0.009), intima-media thickness (p = 0.001) and diabetes mellitus (p = 0.042) were significantly associated with an increased risk of CV mortality, and age (p = 0.007) and cholesterol (p = 0.002) were independent variables significantly associated with increased total mortality rates. Conclusions: The results of the present study showed that the main predictors of adverse CV events in high-risk hypertensive patients were years of age, cholesterol levels, diabetes, intima-media thickness, and carotid arteries plaques.

C-Reactive Protein as a Predictor of Severe Respiratory Complications in Measles

“…Categorical variables were compared using a Chi-squared or Fischer's exact test, depending on group size. The statistical package SPSS (version 21.0, IBM Corp, 2012; Armonk, NY, USA) was used for all statistical data processing [12]. A two-sided p < 0.05 was considered to be statistically significant.…”

Blood monocyte to high density lipoprotein cholesterol ratio (MHR) can be used as an independent risk factor of carotid artery plaque

“…This study found that the proportion of subjects with diabetes and hypertension did rise with the severity of plaque. This may caused by disorders of glucose and lipid metabolism in most diabetes or hypertension patients, and the incidence of carotid plaques is increased [29][30][31][32][33]. Thus in further analysis, we compared subjects with diabetes, hypertension and those without these two diseases respectively.…”

“…Patients with missing data were excluded from the study at its very beginning when the data were collected. The statistical package SPSS (version 21.0, Armonk, NY, USA: IBM Corp, 2012) was used for all of the statistical data processing [15]. A two-sided p < 0.05 was considered to be statistically significant.…”
