Left ventricular hypertrophy (LVH) in arterial hypertension (AH) is one of the modifiable risk factors for cardiovascular events and serves as a justified goal for antihypertensive therapy. The article presents follow-up of a 60-year-old female with AH, hyperlipidemia, and discovered of LVH on the data of electrocardiography and echocardiography. In addition to the SokolowLyon and Cornell voltage criteria, the baseline echocardiographic examination revealed and increase in thickness of the ventricular septum and the left ventricular (LV) posterior wall, an increase in LV myocardial mass and LV myocardial mass index. The patient was recommended to take a drug of the class of angiotensin converting enzyme inhibitors perindopril and atorvastatin. The patient regularly received therapy and periodically underwent repeated echocardiographic examinations. After 40 months follow-up there are a significant decrease in septal hypertrophy (from 1.22 to 0.76 cm, -37.7%), LV posterior wall (from 1.05 to 0.49, -53.3%), as well as LV myocardial mass (from 197.9 to 96 g, -51.5%) and LV myocardial mass index (from 111.18 to 59.11 g/ m2, -51.5%). Thus, during the entire period of follow-up, the LV mass decreased almost twice. There was a decrease in the size of the left atrium, the relative wall thickness, with the same parameters of LV volumes, characteristics of systolic and diastolic function. Among the favorable factors contributing to significant LVH regression, high adherence to treatment, the efficacy of angiotensin converting enzyme inhibitors and the possible antihypertrophic influence of atorvastatin are discussed.
