| Popis: | The aim of the work was to compare the integral parameters of the vectorcardiogram (VCG) - spatial QRS-T angle and electrocardiographic ventricular gradient (VG) - with clinical data in patients with chronic coronary heart disease (CHD). The study included 213 patients with CHD (165 men and 48 women, mean age 62.1±9.8 years) who underwent a comprehensive clinical and instrumental examination. The control group consisted of 50 practically healthy persons (30 women and 20 men, mean age 56.5±8.8 years). The QRS-T angle and VG were calculated on the VCG, derived from the 12-lead digital ECG. In patients with CHD, the VG module and VG-X, VG-Y, VG-Z components were significantly smaller, and the QRS-T angle was significantly higher than in healthy individuals of the same sex. The presence of arterial hypertension, hyperlipidemia, diabetes mellitus, chronic heart failure and obesity was associated with increased QRS-T angle. In patients who had a history of anterior myocardial infarction, compared to patients without myocardial infarctions, the VG module and its components VG-X and VG-Z were significantly decreased and the QRS-T angle was increased. In patients who had a history of inferior-posterior myocardial infarction, the VG-Y component was significantly decreased and the VG-Z component was increased. The threshold value VG-Y |
