Quantitative assessment of some risk factors of chronic cardiac failure and non-invasive diagnosis of its early (preclinical) stages

Factors of risk of chronic circulatory insufficiency (CCI) were assessed in 263 hypertensive patients with and without ischemic heart diseases. CCI was diagnosed in 218 of these 263 patients. Early stages of CCI may be diagnosed in certain number of these factors. ECG findings in isolated arterial hypertension detected left ventricular dysfunction classified as chronic cardiac failure of functional class I (NYHA criteria).
