Abstract

Abstract : Objective: Microvascular angina or cardiac syndrome X, describes patients with anginal chest pain, signs of ischaemia on ECG and a positive stress test, but with non-obstructive coronary angiography. Coronary heart disease is the main cause of mortality in many Western countries and is represented by stable angina pectoris, unstable angina pectoris, myocardial infarction without ST segment elevation (NSTEMI) and myocardial infarction with ST segment elevation (STEMI). The aim of this study was to examine differences in the values of diastolic blood pressure in patients with microvascular angina and patients with CAD including stable angina, unstable angina, STEMI and NSTEMI. Design and method: This study included 375 patients, of whom 75 with microvascular angina and 300 patients with CAD (75 patients with stable angina, 75 patients with unstable angina, 75 patients with NSTEMI and 75 patients with STEMI) who were treated at the Clinic for Cardiology, Clinical Centre Kragujevac in the period from 2005. to 2013. All patients with MVA were taken into account, while patients with CAD were randomised using randomising tables. Blood pressures were measured 30 minutes after admission. All data was entered into SPSS and statistically processed using descriptive and analytical methods. Results: Values of diastolic blood pressure were significantly different between patients with MVA and all patients with CAD, with higher values in patients with CAD (81.40 ± 10.83 versus 84.84 ± 12.53; p = 0.030). When comparing values of diastolic blood pressure between the groups (MVA vs. stable angina, unstable angina, NSTEMI and STEMI), significantly higher values were noticed between patients with MVA and patients with NSTEMI (81.40 ± 10.83 versus 85.47 ± 11.40; p = 0.027) and patients with MVA and patients with STEMI (81.40 ± 10.83 versus 90.51 ± 15.98; p < 0.001), while there was no significantly difference between patients with MVA and stable angina (81.40 ± 10.83 versus 82.20 ± 10.21; p = 0.642) and patients with MVA and unstable angina (81.40 ± 10.83 versus 81.20 ± 9.58; p = 0.905). Conclusions: Values of diastolic blood pressure were significantly different between patients with MVA and CAD, more precisely between patients with MVA and patients with NSTEMI and STEMI, while the significance was not present between patients with MVA and stable and unstable angina pectoris.
