More detailed estimation for future cardiovascular events has to be deeper than quick assessment with, for example, SCORE tables and should include arterial stiffness measurement with ePWV and ECG analysis. The aim of this observational longitudinal study was to determine the correlation between ePWV and ECG abnormalities, as well as correlation between number of death events and analyzed biomarkers. Population was divided according to arterial pressure: optimal arterial pressure (<=119/79mmHg), prehypertension (120-139/80-89mmHg) and untreated hypertension (>=140/90mmHg). Conducted analysis has found correlation between Sokolow voltage criteria for left ventricular hypertrophy and ePWV in group with optimal arterial pressure. Even though causality was not analyzed, this correlation emphasizes the importance of ePWV as independent risk factor, which probably causes intermittent elevation of arterial pressure and can cause left ventricular hypertrophy. A lot of examiners with left ventricular hypertrophy has not been directly included in analysis since Sokolow voltage criteria has high specificity (95%) and low sensitivity (20-30%). Due to well-known facts that left ventricular hypertrophy is connected to ECG markers of repolarization, QT and QTc, but also to atrial fibrillation due to increased arterial pressure, there is a possibility that the indirect correlation was found between ePWV and left ventricular hypertrophy in the prehypertension and untreated hypertension group. Conducted analysis has found correlation between atrial fibrillation and ePWV in prehypertension and correlation between QT and QTc with ePWV in untreated hypertension group. The obtained results show the need for additional analyzes on a larger number of respondents, primarily in the group of respondents involved in the EH-UH 2 project.
