The aim: The purpose of the present research was to study the results of coronary artery bypass graft (CABG) surgery depending on the degree of left ventricular ejection fraction (LVEF) reduction with the aim to identify additional echocardiographic predictors of the early postoperative period.
Materials and methods: Were fixed, the results of CABG in 97 patients operated on in the “Bikard” private clinic from March 2016 to December 2018 were the material of the
research. All patients underwent CABG surgery under cardiopulmonary bypass and cardioplegia, and in the preoperative period underwent echocardiographic examination
according to the standard technique on the Vivid 7 machine. Patients, in dependent of the LVEF, were divided into 3 groups: group 1 35 people (LVEF < 40%), group 2 32 people ( 40% < LVEF < 50%), group 3 30 people (LVEF > 50%).
Results: Our studies showed that the most important echocardiographic predictors of a complicated development of the disease in the early postoperative period, in addition
to LVEF of the heart, can be the size of the left ventricle and left atrial, the presence and severity of mitral regurgitation and diastolic dysfunction of the left ventricle of the heart.
Conclusions: Comprehensive measurement of these echocardiographic parameters will allow more accurately predict the results of coronary artery bypass grafting in the
early postoperative period.
Introduction:
Global climate change is already affecting the health, living conditions, and livelihoods of people on all continents. According to many researchers, the deterioration of the patient's condition is manifested after a solar flare, with the onset of a magnetic storm.
Aim:
The aim of the article is to study the influence of heliogeophysical factors on the development and outcomes of myocardial infarction.
Material and methods:
Using data on the effect of space weather on a person from France, Germany, China, Israel, Lithuania, Georgia, a number of Russian clinics – wherever patients with ischemic heart disease were observed, during magnetic storms.
Results and discussion:
An in-depth study of mortality from myocardial infarction in various climatic and geographical regions showed the dependence of the number of deaths on the season of the year and sharp fluctuations in individual meteorological parameters of the weather to a much greater extent in the year of solar activity.
Conclusions:
It was found that patients with cardiovascular diseases (CVD) are especially susceptible to heliogeophysical disturbances. The number and severity of CVD depend on many environmental factors (atmospheric pressure, air temperature, cloud amount, ionisation, radiation regime, etc.), a reliable and stable relationship of CVD is revealed with chromospheric flares and geomagnetic storms.
