RESUMO

BACKGROUND: There is enough evidence of the negative impact of excess weight on the formation and progression of res piratory pathology. Given the continuing SARS-CoV-2 pandemic, it is relevant to determine the relationship between body mass index (BMI) and the clinical features of the novel coronavirus infection (NCI). AIM: To study the effect of BMI on the course of the acute SARS-COV-2 infection and the post-covid period. MATERIALS AND METHODS: AKTIV and AKTIV 2 are multicenter non-interventional real-world registers. The АКТИВ registry (n=6396) includes non-overlapping outpatient and inpatient arms with 6 visits in each. The АКТИВ 2 registry (n=2968) collected  the  data  of  hospitalized  patients  and  included  3  visits.  All  subjects  were  divided  into  3  groups:  not  overweight  (n=2139), overweight (n=2931) and obese (n=2666). RESULTS: A higher BMI was significantly associated with a more severe course of the infection in the form of acute kidney injury (p=0.018), cytokine storm (p<0.001), serum C-reactive protein over 100 mg/l (p<0.001), and the need for targeted therapy (p<0.001) in the hospitalized patients. Obesity increased the odds of myocarditis by 1,84 times (95% confidence interval [CI]: 1,13-3,00) and the need for anticytokine therapy by 1,7 times (95% CI: 1,30-2,30).The  patients  with  the  1st  and  2nd  degree  obesity,  undergoing  the  inpatient  treatment,  tended  to  have  a  higher  probability  of  a  mortality  rate.  While  in  case  of  morbid  obesity  patients  this  tendency  is  the  most  significant  (odds  ratio  -  1,78; 95% CI: 1,13-2,70). At the same time, the patients whose chronical diseases first appeared after the convalescence period, and those who had certain complaints missing before SARS-CoV-2 infection, more often had BMI of more than 30 kg/m2 (p<0,001).Additionally, the odds of death increased by 2,23 times (95% CI: 1,05-4,72) within 3 months after recovery in obese people over the age of 60 yearsCONCLUSION.  Overweight  and/or  obesity  is  a  significant  risk  factor  for severe  course  of  the  new  coronavirus  infection  and  the associated cardiovascular and kidney damage Overweight people and patients with the 1st and 2nd degree obesity tend to have a high risk of death of SARS-CoV-2 infection in both acute and post-covid periods. On top of that, in case of morbid obesity patients this tendency is statistically significant. Normalization of body weight is a strategic objective of modern medicine and can contribute to prevention of respiratory conditions, severe course and complications of the new coronavirus infection.

RESUMO

Aim To study the antianginal and heart rate slowing effects in patients with stable angina (SA) who failed to achieve the heart rate (HR) goal and were switched from the beta-blocker (BB) metoprolol tartrate to a combination of metoprolol tartrate and ivabradine.Materials and methods The study included 54 patients with SA not higher than functional class (FC) III (35 (64.8 %) men and 19 (35.2 %) women) aged 59 [48; 77] years. Prior to the study start and at 4 and 8 weeks of follow-up, electrocardiography (ECG) and 24-h ECG monitoring (24h-ECGM) were performed for all patients. The follow-up period duration was 8 weeks. The antianginal and heart rate slowing effects of therapy were clinically evaluated by a decrease in frequency of anginal attacks and patients' requirement for nitrates, a decrease in HR, and the effect on 24h-ECGM indexes characterizing myocardial ischemia. At the first stage, all patients were prescribed metoprolol tartrate (Egilok®, Egis, Hungary) 25 mg twice a day. Patients with resting HR still higher than 70 bpm after 4 weeks of treatment were switched from metoprolol tartrate to a fixed ivabradine/metoprolol combination (Implicor®, Servier, France) 5 / 25 mg twice a day. Thus, based on achieving/ non-achieving the HR goal, two groups of patients were formed. Statistical analysis was performed with a STATISTICA 10,0 software package.Results After 4 weeks of therapy with metoprolol tartrate 25 mg twice a day, 18 (33.3%) patients of group 1 achieved the HR goal of 70 bpm, while  36 (66.7%) patients of group 2 did not achieve the goal. For further correction of HR, patients of group 2 were switched from metoprolol tartrate to ivabradine/metoprolol 5 / 25 mg twice a day. After 4 weeks of the ivabradine/metoprolol treatment, 31 (86.1 %) patients achieved the HR goal with median resting HR of 62 [56; 70] bpm. The number of angina attacks decreased from 6 [3; 8] to 2 [1; 3] per week (р<0.001). 24hECGM showed that the mean diurnal HR decreased from 81 [76; 96] to 66 [56; 76] bpm (р<0.001); mean night HR decreased from 69 [73; 80] to 52 [43; 60] bpm (р=0.012); and the ischemic ST segment depression was absent.Conclusion Only 33.3% of patients with stable angina achieved the HR goal on metoprolol tartrate 25 mg twice a day. Supplementing the beta-blocker metoprolol tartrate at the same dose with ivabradine allowed 86.1% of patients to achieve the HR goal and exerted a pronounced anti-anginal effect.

RESUMO

The aim of the investigation was to study the parameters of high-frequency ECG in leads V1, V3R, V4R, V5R, V6R as additional diagnostic criteria for detecting the areas of myocardial ischemia associated with stenosis of the right coronary artery (RCA) in IHD patients. MATERIALS AND METHODS: The study involved 47 patients who underwent selective coronary angiography (SCA) for detection of IHD. The patients were divided into two groups based on the SCA results: group 1 included 28 patients with hemodynamically significant RCA stenosis; group 2 consisted of 19 patients with hemodynamically non-significant RCA stenosis. Prior to SCA, all patients underwent resting high-frequency ECG recording in 12 conventional leads and in leads V3R-V6R for 5 min. The study also involved 15 volunteers with no history of cardiovascular disease or IHD symptoms (control group) who underwent ECG in the same leads. The resulting data were processed and analyzed using the ArMaSoft-12-Cardio software (©ArMaSoft, 1995-2019, Russia), which made it possible to determine the presence or absence of reduced amplitude zones (RAZ) of the QRS complex in all morphological variants, the root-mean-square (RMS) deviation, and excess kurtosis. RESULTS: Statistically significant differences in the RAZ parameter of the QRS complex were revealed in high-frequency ECG of patients with hemodynamically significant and non-significant RCA stenosis. The RAZ sum in leads V1, V3R, V4R, V5R, V6R was 7.86±0.77 and 3.58±0.53, respectively, while in patients with no IHD signs, it equaled 1.87±0.43 (p=0.00001).The RMS value in patients with no IHD signs was 3.89±0.42, in patients with hemodynamically non-significant and significant RCA stenosis it equaled 3.51±0.34 and 2.73±0.24, respectively (p=0.008).The kurtosis value was statistically significantly higher in patients with hemodynamically significant stenosis (1.07±0.12), in contrast to those with hemodynamically non-significant stenosis and without IHD (0.78±0.05 and 0.64±0.03, respectively).An average correlation between the value of coronary stenosis and the sum of RAZ scores was found (r=0.66).However, RMS and kurtosis parameters correlate with the degree of RCA stenosis at a lower level.According to ROC analysis, the RAZ parameter showed better diagnostic results compared to RMS and kurtosis. Given the nonparametric nature of the available data, the prognostic capabilities of the studied parameters can be considered satisfactory as shown by the results of binary logistic regression. CONCLUSION: The RAZ parameter of high-frequency ECG in leads V1, V3R, V4R, V5R, V6R may serve as an additional diagnostic criterion for identifying the areas of myocardial ischemia associated with RCA stenosis in IHD patients.

RESUMO

AIM: the study of comorbid status and characteristics of clinical course of ischemic heart disease (IHD) in patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: We conducted a retrospective analysis of case histories of 958 IHD patients aged 32 to 93 years (mean age of 60.8±10.2 years), including men - 525 (54.8%), women - 433 (45.2%) who were treated in the cardiology Department of city clinical hospital №5 of Nizhny Novgorod. Related COPD was diagnosed in 251 patients (26.3%). We compared two groups patients: with IHD and COPD, and the second - persons suffering from only IHD (without COPD). RESULTS: Myocardial infarction was transferred by 62.2% of patients in Group 1, which is 16.3% more than in Group 2 (p<0.05). Arterial hypertension in patients with COPD was 13.6% more frequent than in patients without COPD (p<0.05), and 6.4% more often (p<0.05), with comorbid pathology there was a chronic and paroxysmal forms of atrial fibrillation. In patients with IHD in combination with COPD it is 21.5% more often (p<0.05) than in IHD without COPD, there was shortness of breath and 32.1% more often (p<0.05) of the heartbeat. In patients with IHD with COPD, a higher level of was C-reactive protein detected (p<0.05) and more pronounced violations of the lipid profile (p<0.05). CONCLUSION: COPD makes a significant contribution to the development of the cardiovascular continuum, modifying its course. A modern patient with COPD is a high-risk patient with severe cardiovascular comorbidity and various polymorbidity.
