Arterial hypertension and diabetes in patients with stable angina undergoing coronary angiography

Aim: The aim of the study was to assess the rate of hypertension and diabetes in patients with stable angina (CAD) admitted for coronary angiography and analyse other risk factors of CAD. Material and methods: In this retrospective study we enrolled 403 patients, age 65.41 ±9.6 years, with stable CAD admitted for coronary angiography. The patients were divided into 2 groups: patients with hypertension and diabetes and a group with hypertension. Results: Hypertension was diagnosed in 335 patients (83.10%). The majority of the patients were over 65 years old. There were 96 patients in the study group and 239 in the control group. Thirty-one patients had been using insulin and 65 patients oral agents. Blood pressure values in the patients with diabetes and without diabetes were similar - 135 mm Hg vs. 134 mm Hg for systolic blood pressure and 79 mm Hg vs. 80 mm Hg for diastolic (p = NS and p = NS). During hospitalization we observed a drop in systolic blood pressure in the patients without diabetes by 10 mm Hg. After 3 days of hospitalization blood pressure values were also significantly higher in patients with diabetes (p = 0.026). On admission patients using insulin had systolic blood pressure higher by 10 mm Hg than the patients using oral agents. During hospitalization the difference between systolic blood pressure in the patients using insulin and oral agents was 10 mm Hg. There was a significant correlation between systolic blood pressure and the kind of treatment of diabetes (p = 0.012). Conclusions: We observed a high rate of hypertension and diabetes among patients with stable CAD hospitalized due to coronary angiography. Both hypertension and diabetes were more frequent in patients over 65 years old. Values of blood pressure were similar in the group with and without diabetes. Patients treated with insulin had significantly higher blood pressure than patients treated with oral glucose lowering agents both on admission and during hospitalization.
