Clinical and Anamnestic Characteristics, Cardiovascular Pharmacotherapy and Long-term Outcomes in Multimorbid Patients after COVID-19

Aim. To study the clinical and anamnestic characteristics, pharmacotherapy of cardiovascular diseases (CVD) and long-term outcomes in post-COVID-19 patients with cardiovascular multimorbidity (CVMM), enrolled in the prospective hospital registry.Material and methods. In patients with confirmed COVID-19 included in the TARGET-VIP registry, the CVMM criterion was the presence of two or more CVDs: arterial hypertension (AH), coronary heart disease (CHD), chronic heart failure (CHF), atrial fibrillation (AF). There were 163 patients in the CVMM group and 382 – in the group without CVD. The information was obtained initially from hospital history sheet, and afterwards – from a telephone survey of patients after 30-60 days, 6 and 12 months, from electronic databases. The follow-up period was 13.0±1.5 months.Results. The age of post-COVID patients with CVMM was 73.7±9.6 years, without CVD – 49.4±12.4 years (p<0.001), the proportion of men was 53.9% and 58.4% (p=0.34). In the group with CVMM the majority of patients had AH (92.3-93.3%), CHD (90.4-91.4%), and minority – CHF (42.7-46.0%) and AF (42.9-43.4%). The combination of 3-4 CVDs prevailed (58.9-60.3%). The proportion of cases of chronic non-cardiac pathologies was higher in the CVMM group (80.9%) compared to the group without CVD (36.7%; p<0.001). The frequency of proper cardiovascular pharmacotherapy during the follow-up period decreased from 56.8% to 51.3% (p for trend = 0.18). The frequency of anticoagulant therapy in AF decreased significantly: from 89.1% at the discharge from the hospital to 56.4% after 30-60 days (p=0.001), 57.1% and 53.6% after 6 and 12 months of monitoring (p for a trend <0.001). There were no other significant changes in the frequency of other kinds of the proper cardiovascular pharmacotherapy (p>0.05). There were higher rate of all-cause mortality among patients with CMMM (12.9% vs 2.9%, p<0.001) as well as rates of hospitalization (34.7% and 9.9%, p<0.001) and non-fatal myocardial infarction (MI) – 2.5% vs 0.5% (p=0.048). The proportion of new cases of CVD in the groups with CVMM and without CVD was 5.5% and 3.7% (p=0.33). The incidence of acute respiratory viral infection (ARVI)/influenza was higher in the group without CVD – 28.3% vs 19.0% (p=0.02). The proportion of cases of recurrent COVID-19 in groups with CVMM and without CVD was 3.7 % and 1.8% (p=0.19).Conclusion. Post COVID-19 patients with CVMM were older and had the bigger number of chronic non-cardiac diseases than patients without CVD. The quality of cardiovascular pharmacotherapy in patients with CVMM was insufficient at the discharge from the hospital with following non-significant decrease during 12 months of follow-up. The frequency of anticoagulant therapy in AF decreased by 1.6 times after 30-60 days and by 1.7 times during the year of follow-up. The proportion of new cases of CVD was 5.5% and 3.7% with no significant differences between compared groups. The rate of all-cause mortality, hospitalizations and non-fatal MI was significantly higher in patients with CVMM, but the frequency of ARVI/influenza was significantly higher in patients without CVD. Recurrent COVID-19 was registered in 3.7% and 1.8% of cases, there were no significant differences between compared groups

Long-term outcomes in patients after COVID-19: data from the TARGET-VIP registry

Aim. To assess long-term outcomes within 12 months after hospital treatment of patients with coronavirus disease 2019 (COVID-19) as part of a prospective registry.Material and methods. Outcomes in the posthospital period were assessed in 827 patients diagnosed with COVID-19 (age, 58,0±14,8 years; men, 51,3%). For periods of 30-60 days, 6 and 12 months after discharge from the hospital, cases of death, nonfatal myocardial infarction (MI) and stroke, hospitalization, acute respiratory viral infections/influenza were assessed. The follow-up period was 13,0±1,5 months.Results. During the follow-up period, 35 (4,2%) patients died, 6 (0,73%) and 4 (0,48%) cases of MI and stroke were registered. In addition, 142 (17%) patients were hospitalized, while 217 (26,2%) patients had acute respiratory viral infections/ influenza. Factors of age and length of intensive care unit stay were significantly associated (p<0,001) with the risk of all-cause death (hazard ratio (HR)=1,085 per 1 year of life and HR=6,98, respectively), with the risk of composite endpoint (death, non-fatal MI and stroke): HR=1,081 per 1 year of life and HP=4,47. Of the 35 deaths, 11 (31%) were within the first 30 days of follow-up, and 19 (54%) — 90 days after discharge from the hospital. A higher probability of hospitalization was associated with older age (odds ratio (OR)=1,038; p<0,001), while a higher probability of acute respiratory viral infections/influenza was associated with younger age (OR=0,976 per 1 year of life; p<0,001) and female sex (OR=1,414; p=0,03).Conclusion. A prospective follow-up of 827 patients in the TARGET-VIP registry revealed that 12-month mortality was 4,2%, while more than half of the deaths (54%) were registered in the first 90 days, including 31% — for the first month after discharge from the hospital. The most common events were hospitalizations (17,0%) and acute respiratory viral infections/influenza (26,2%), while the rarest were myocardial infarction (0,73%) and stroke (0,48%). The key factors associated with 12-month mortality in the post-COVID-19 period were older age and intensive care unit stay during the reference hospitalization. A higher readmission rate during the follow-up period was associated with older age, and the prevalence of acute respiratory viral infections /influenza during the follow-up period was associated with younger patients and female sex

Patients with a Combination of Atrial Fibrillation and Chronic Heart Failure in Clinical Practice: Comorbidities, Drug Treatment and Outcomes

Aim. To assess in clinical practice the structure of multimorbidity, cardiovascular pharmacotherapy and outcomes in patients with a combination of atrial fibrillation (AF) and chronic heart failure (CHF) based on prospective registries of patients with cardiovascular diseases (CVD).Materials and Methods. The data of 3795 patients with atrial fibrillation (AF) were analyzed within the registries RECVASA (Ryazan), RECVASA FP (Moscow, Kursk, Tula, Yaroslavl), REGION-PO and REGION-LD (Ryazan), REGION-Moscow, REGATA (Ryazan). The comparison groups consisted of 3016 (79.5%) patients with AF in combination with CHF and 779 (29.5%) patients with AF without CHF. The duration of prospective observation is from 2 to 6 years.Results. Patients with a combination of AF and CHF (n=3016, age was 72.0±10.3 years; 41.8% of men) compared with patients with AF without CHF (n=779, age was 70.3±12.0 years; 43.5% of men) had a higher risk of thromboembolic complications (CHA2DS2-VASc – 4.68±1.59 and 3.10±1.50; p<0.001) and hemorrhagic complications (HAS-BLED – 1.59±0.77 and 1.33±0.76; p<0.05). Patients with a combination of AF and CHF significantly more often (p<0.001) than in the absence of CHF were diagnosed with arterial hypertension (93.9% and 83.8%), coronary heart disease (87.9% and 53,5%), myocardial infarction (28.4% and 14.0%), diabetes mellitus (22.4% and 7.7%), chronic kidney disease (24.8% and 16.2%), as well as respiratory diseases (20.1% and 15.3%; p=0.002). Patients with AF in the presence of CHF, compared with patients without CHF, were more often diagnosed with a permanent form of arrhythmia (49.3% and 32.9%; p<0.001) and less often paroxysmal (22.5% and 46.2%; p<0.001) form  of  arrhythmia.  Ejection  fraction  ≤40%  (9.3%  and  1.2%;  p<0.001),  heart  rate  ≥90/min  (23.7% and 19.3%; p=0.008) and blood pressure ≥140/90 mm Hg (59.9% and 52.2%; p<0.001) were recorded with AF in the presence of CHF more often than in the absence of CHF. The frequency of proper cardiovascular pharmacotherapy was higher, albeit insufficient, in the presence of CHF (64.9%) than in the absence of it (56.1%), but anticoagulants were prescribed less frequently when AF and CHF were combined (38.8% and  49, 0%; p<0.001). The frequency of unreasonable prescription of antiplatelet agents instead of anticoagulants was 52.5% and 33.3% (p<0.001) in the combination of AF, CHF and coronary heart disease, as well as in the combination of AF with coronary heart disease but without CHF. Patients with AF and CHF during the observation period compared with those without CHF had higher mortality from all causes (37.6% and 30.3%; p=0.001), the frequency of non-fatal cerebral stroke (8.2% and 5.4%; p=0.032) and myocardial infarction (4.7% and 2.5%; p=0.036), hospitalizations for CVD (22.8% and 15.5%; p<0.001).Conclusion. Patients with a combination of AF and CHF, compared with the group of patients with AF without CHF, were older, had a higher risk of thromboembolic and hemorrhagic complications, they were more often diagnosed with other concomitant cardiovascular and chronic noncardiac diseases, decreased left ventricular ejection fraction, tachysystole, failure to achieve the target blood pressure level in the presence of arterial hypertension. The frequency of prescribing proper cardiovascular pharmacotherapy was higher, albeit insufficient, in the presence of CHF, while the frequency of prescribing anticoagulants was less. The  incidence of mortality from all causes, the development of non-fatal myocardial infarction   and cerebral stroke, as well as the incidence of hospitalizations for CVDs were higher in AF associated with CHF

OUTPATIENT REGISTER OF CARDIOVASCULAR DISEASES IN THE RYAZAN REGION (RECVASA): PRINCIPAL TASKS, EXPERIENCE OF DEVELOPMENT AND FIRST RESULTS

Aim. To estimate risk factors and comorbidity structure, cardiovascular diseases outcomes, evaluate their diagnostics and treatment quality in real outpatient practice using a register of patients with arterial hypertension (HT), ischemic heart disease (IHD), chronic heart failure (CHF) and atrial fibrillation (AF) in the Ryazan Region – the territorial subject ofRussian Federation with high cardiovascular mortality rate.Material and methods. The total of 1000 HT, IHD, CHF, AF patients, applied for general practitioners or cardiologists of theRyazan outpatient clinics in March-May of 2012 were sequentially enrolled in the outpatient REgister of CardioVAscular diseases (RECVASA).Results. According to outpatient cards data HT, IHD, CHF and AF were diagnosed in 99.0%; 70.9%; 74.8% and 13.7% of the 1000 cases, respectively. 820 (82%) patients revealed a concomitant cardiovascular pathology (cardiac comorbidity), at that the most frequent was combination of HT with IHD and CHF (50.4%). Diabetes mellitus was diagnosed in 209 (20.9%) patients. 770 (77%) patients were assessed on their total cholesterol level; smoking status and family history of heart diseases were estimated in 28 (2.8%) and 49 (4.9%) patients, respectively. Exercise tolerance test (stress-test) was carried out in 2% of the patients (including 2.8% of the IHD patients), 24-hour blood pressure (BP) and ECG monitoring – in 0.7% and 5.5%, respectively; echocardiography and ultrasound of brachiocephalic arteries (BCA) – in 25.6% and 8.6%, respectively; coronary angiography – in 1.6% (which includes 2.3% of the IHD patients). The following drug groups were prescribed most frequently: antiplatelet agents – in 60.4% of the cases (584 patients received acetylsalicylic acid and 20 – clopidogrel), ACE inhibitors – in 62.9%, β-blockers – in 43.9% of the patients. Target BP level was achieved in 245 of 956 cases (25.6%). 50.6% of IHD patients and 51.1% of hypercholesterolemic patients received statins.Conclusion. The pilot stage of the RECVASA study revealed a high incidence rate of cardiac comorbidity (82%) in patients with hypertension, IHD, CHF and AF, insufficient estimation of cardiovascular risk factors, inadequate frequency of stress-tests, 24-hour BP and ECG monitoring, echocardiography, BCA sonography, coronary angiography use, as well as a scarce prescription of warfarin in AF and statins in hypercholesterolemic patients. Improvement of correspondence to national guidelines is the main reserve for enhancement of diagnostics and treatment quality in patients with HT, IHD, CHF, AF and hypercholesterolemia

Structure of Alloys for (Sm,Zr)(Co,Cu,Fe)z Permanent Magnets: II. Composition, Magnetization Reversal, and Magnetic Hardening of Main Structural Components

Experimental series of alloys for (Sm,Zr)(Co,Cu,Fe)Z permanent magnets are presented in the concentration ranges that provide wide variations of (4f)/(4d)/(3d) ratios of comprising elements. Optical metallographic analysis, observation of the surface domain structure upon magnetization reversal (Kerr effect), electron microprobe analysis, and measuring the major hysteresis loops of samples at different stages of heat treatment are used to study processes related to the development of the highly coercive state of these samples. It was found that the volume fractions of two main structural components A and B, which comprise 90% of the total sample volume, rigorously control the coercivity at all stages of thermal aging. At the same time, structural components A and B themselves in samples being in the high-coercivity state differ qualitatively and quantitatively in the chemical composition, domain structure and its development in external magnetic fields and, therefore, are characterized by different morphologies of the phases comprising the structural components. Two stages of phase transformations in the sample structure are observed. During isothermal annealing, the cellular structure develops within the B component, whereas, during stepwise (slow) cooling or quenching from the isothermal aging temperature to 400 °C, a phase structure evolves within both the cell boundaries in B and the structural component A. The degree of completion of the phase transformations within micro- and nano-volumes of the components determines the ultimate hysteretic characteristics of the material

Young ambulatory patients with cardiovascular diseases: age and gender characteristics, comorbidity, medication and outcomes (according to RECVASA register)

Aim. To assess age and gender characteristics and determine comorbidity, medication, and outcomes in young ambulatory patients with cardiovascular diseases (CVD) within the framework of an ambulatory prospective registry.Material and methods. The study included 3690 patients with hypertension (HTN), coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), and combinations thereof, which applied to 3 Ryazan hospitals. Younger CVD patients (criterion 1 — the age of 18-49 years, criterion 2 — the age of men 18-54 years old and women 18-64 years old) were compared with older representatives. The presence of CVD and comorbidities, medication, and outcomes over 6 year follow-up were analyzed.Results. The age groups of 18-49 years old and >50 years old included 347 (9,4%) and 3343 (90,6%) patients, respectively (men — 144 (41,5%) and 902 (27,0%), p<0,0001). According to criterion 2, 1369 (37,1%) people were assigned to the group of young CVD patients (men <55 years old — 254 (18,6%) and women <65 years old — 1115 (81,4%)). The older group included 2321 people (men — 792 (34,1%) and women — 1529 (65,9%)). In younger CVD patients (by criteria 1 and 2), the proportion of people with CAD, HF, AF, history of myocardial infarction (MI) and/or stroke, diabetes, respiratory and digestive diseases were significantly lower (p<0,001); there was also a lower proportion of people with cardiovascular multimorbidity. According to criterion 1, the proportion of younger people with >2 CVDs was 41%; according to criterion 2 — 62% (p<0,0001). Among patients <50 years of age, AF and stroke occurred in less than 5% of cases; MI was observed only in men. When using criteria 1 and 2 in patients with early CVD development compared with older patients, there was a larger proportion of obesity cases — 19,3% and 20,2% vs 13,8% and 10,8%, respectively (p=0,002 and p=0,019) and according to criterion 2, anemia cases — 10,2% and 7,1%, respectively (p=0,004). In younger patients, there were higher proportion of adequate medication — 70,9% and 68,8% vs 58,5% and 64,6% (p<0,001), lower mortality — 9,8% and 10,4% vs 30,8% and 39,7% (p<0,001). However, reinfarction incidence in men <50 years old was higher — 22,7% vs 12,4% (p=0,04).Conclusion. In younger CVD patients compared with older patients, in accordance with criteria 1, there was a large proportion of men; in accordance with criteria 1 and 2 — lower incidence of CVD and noncardiac diseases, with the exception of obesity and anemia cases (only by criterion 2). Criterion 1 is more applicable for HTN, CAD, and CHF, while criterion 2 — for AF, stroke, and myocardial infarction. Younger CVD patients according to both criteria were characterized by a higher proportion of adequate medication, as well as lower mortality, the incidence of non-fatal stroke and CVD hospitalization. Men with MI history at the age of <50 years have higher reinfarction risk. CVD patients at the age of <50 years old are the target group for the prevention of cardiovascular multimorbidity and its progression
