Increased platelet adhesion and aggregation has been reported in patients suffering from rheumatic valvular heart disease and from atherosclerotic heart disease. We therefore measured spontaneous aggregation “PAT III” (Breddin) and ADP-induced platelet aggregation (Born) in 141 patients who underwent cardiac catheterization. There were 50 patients with coronary heart disease, 41 with valvular heart disease, 18 with cardiomyopathy; 32 with normal findings at catheterization served as control group.In comparison to controls, patients with coronary heart disease had significantly increased aggregation. Subdivision into 1, 2, or 3 vessel disease revealed no significant differences. Patients with valvular heart disease also had significantly increased aggregation. This appears to be particularly the case after valvular grafting. Cardiomyopathies were not associated with increased platelet aggregation.

The non-valvular AF, beyond the guidelines, include 2 types of patients. We aimed to analyze the clinical and biological profile of patients with non-valvular atrial fibrillation (AF)andhemodynamicsignificantvalvular heart disease. We includedretrospectively 513 patients admitted in our hospitalwithnon-valvular AF, and we divided into:study group(333 patients; 64.9%) andcontrole group(180 patients; 35.1%) hemodynamic significant valvular heart disease. From the studied group 5.5% of patients associated all four valvular heart disease, 26.7% ofpatients associated mitral, aortic and tricuspid regurgitation and 71.9%of patients associated two valvular heart disease: 32.7% with mitral and aortic, 31.4% with mitral and tricuspid, 4.5% with tricuspid and pulmonary, and3.3% withtricuspid and aortic. Dyslipidemia (higher cholesterol and trygliceride levels) was present in 14.5% of patients, statistic significantly more frequently in patients from the control group (11.4% vs 18.3%, P= 0.033). Dyslipidemia showed a significantly higher estimated risk for AF (RR=1.25; IC95%: 0.99-1.56), as well as diabetes mellitus (RR=1.36; IC95%: 1.12-1.64)and coronary heart disease (RR=3.70; IC95%: 1.83-7.46). Therefore patients with non-valvular AF and hemodynamic significant valvular heart disease, beyond the curent guidelines, could has a completely different profile and prognosis.

Abstract Background Arterial stiffness index (ASI) is closely related to coronary atherosclerosis. This study aims to explore whether ASI can predict coronary heart disease (CHD) and its severity. Methods In this study, a total of 726 patients with suspected CHD were recruited. Based on coronary angiography results, the subjects were assigned into three groups: the control group (without obvious coronary artery disease), single-vessel disease group, and multi-vessel disease group (the number of vessels diseased ≥ 2). At the same time, according to the results of angiography, myocardial enzyme spectrum, electrocardiogram, color Doppler echocardiography and clinical manifestations, these patients were divided into four groups: the control group, stable angina (SA) Group, unstable angina (UA) group, and acute myocardial infarction (AMI) group. We have compared whether there were differences in ASI and related baseline data between groups. Receiver operating curve (ROC) analysis was conducted to determine whether ASI could predict CHD and evaluate the severity. Results ASI was positively correlated with the number of diseased branches of coronary artery. The value of ASI was increased as the number of the diseased branches increased. The ASI value in the SA group was significantly higher compared with the control group. Furthermore, the ASI value in the UA and AMI groups was remarkably increased compared with the control and SA groups. The results of ROC analysis indicated that the sensitivity and specificity of ASI was 71.0% and 85.4% in diagnosing CHD, respectively. While ASI was used in predicting the severity of CHD, the sensitivity was 72.1% and specificity 57.9%. Conclusion ASI is of great value in the diagnosis of coronary heart disease and the prediction of its severity.

Objective: To evaluate the value of epicardial adipose tissue (EAT) thickness combined with serum ischemic modified albumin (IMA) concentration in the diagnosis of coronary heart disease. Methods: A total of 180 patients with coronary heart disease from May 2017 to December 2018 were selected as the case group. After the examination of Judkins coronary angiography, they were grouped according to the results of angiography, including 60 patients in a single-vessel group, 60 patients in a double-vessel group, and 60 patients in a multi-vessel group. Sixty healthy people with physical examinations at our hospital at the same time were selected as the control group. All selected participants were tested for epicardial adipose tissue thickness by echocardiography and serum IMA concentration by albumin cobalt ion binding test. Results: The EAT thickness and IMA concentration in the single-vessel disease group, double-vessel disease group, and multi-vessel disease group significantly were higher than those in the control group (P < .01). The ROC curve shows that the sensitivity is 53.33% and the specificity is 87.6%, when the EAT thickness is 6.12 mm. The sensitivity is 76.0% and the specificity is 72.3%, when the serum IMA concentration is 72 U/L. When the two were combined, the sensitivity was 40.15% and the specificity was 96.89%. In the parallel test, the sensitivity was 88.3% and the specificity was 65.44%. Conclusion: Ultrasound detection of EAT thickness and serum IMA concentration has certain reference value for the diagnosis of coronary heart disease. Combined diagnosis can significantly improve the diagnosis rate and accuracy of coronary heart disease.

The number of diabetes mellitus (DM) is steadily increasing and such a rapid increase will lead to an increase in cardiovascular events, mainly due to coronary heart disease (CHD), in which coronary atherosclerosis and its progression is one of the causes of mortality. The course of atherosclerosis is closely related to the state of the hemostasis system. The basis for the development of atherosclerosis is arterial thrombosis, with the activation of platelets playing a leading role in the disruption of hemostasis in coronary heart disease, increasing the risk of thrombotic complications. At present, data on the relationship of different hemostasis units in coronary heart disease in combination with diabetes are mixed, complicating the prognosis of adverse effects taking into account the status of platelet hemostasis. Given the relevance of the topic, the purpose of this study was to evaluate the spontaneous and induced platelet aggregation in patients with various forms of acute coronary heart disease (ACHD) and to identify features of platelet aggregation activity in the combination of ACHD and DM.Adequate reduction of platelet functional activity in patients with coronary heart disease receiving antiplatelet treatment is the basis for effective prevention of thrombus formation in the coronary vessels and the development of adverse cardiovascular events. However, according to the data obtained, the highest activation of platelet hemostasis was observed in the group of patients with ACHD in combination with DM, which showed a significant (relative to the control group) increase in the level of spontaneous platelet aggregation by 4.6 times. At the same time, the percentage of patients who had increased the above indicators was significantly lower in the group of patients with ACHD without disorders of carbohydrate metabolism. In patients with ACHD in combination with DM, activation of the spontaneous aggregation rate was also observed, which accelerated the formation of aggregates by 30% compared with the isolated ACHD group (p <0.05). In the study of induced platelet aggregation, it was taken into account that patients in both groups received dual antiplatelet therapy, which had a significant effect on their activity. However, the expected inhibition of aggregation potential was revealed only by the action of arachidonic acid (AA). Thus, the degree of platelet aggregation in response to AA in group I was 1.9 times significantly lower than the control values ​​of 18.8% [12,1; 26,4], in group II - 1,5 times and made 24,38% [21,5; 32.9] (p <0.001 for both cases). According to ADP-induced platelet aggregation, the effect of antiplatelet drugs was less effective. Thus, a moderate decrease in the degree of ADP-aggregation was observed only in the group of isolated ACHD, whose indicators were 1.42 times lower than in the control group (p <0.01). Thus, dual antiplatelet therapy was accompanied by an effective reduction in platelet function only in the group of patients with isolated ACHD.

To evaluate possibilities of aspirin-induced gastroduodenopathy treatment in the patients with chronic ischemic heart disease by means of applying the internal endogenous prostaglandins stimulant.  Material and methods. 340 patients suffering from chronic coronary heart disease and receiving a long-term acetylsalicylic acid (ASA) therapy were examined on the base of the cardiovascular care unit of The Nizhny Novgorod Regional Clinical Hospital named after N.A. Semaschko. There were evaluated frequency, nature and severity of the aspirin-induced gastroduodenopathy. The patients with coronary heart disease and aspirin-induced gastroduodenopathy were divided in two groups. In the first group of patients there was applied rebamipide therapy (in a single daily dose 300 mg) in combination with the proton pump inhibitor (PPI) — pantoprazole. In the second group there was applied only pantoprazole therapy. For the purpose of specification of AIG pathogenetic mechanisms development, all the examined chronic coronary heart disease cases were tested on the prostaglandin E2 (PGE2) level in blood serum before the therapy beginning and after the treatment. The control group was formed of chronic coronary heart disease patients showing no AIG evidence. Statistical processing of the received data was fulfilled with the program «Statistika 10.0». Results. AIG was registered in 15% out of 340 chronic coronary heart disease patients. According to the endoscopic examination erosive disease of the body and antrum prevailed among the patients. The PGE2 level in the blood serum was significantly lower (р = 0,00087) in these patients in comparison with the control group. In association with PPI and rebamipide mixed therapy, esophagogastroduodenoscopy results showed no pathological findings in gastrointestinal mucosa and statistically significant (р = 0,00067) blood serum PGE2 level growing in all the treated patients. As a result of exclusive PPI therapy there was marked positive dynamics in endoscopic view in 19 out of 25 patients and a tendency to normalization of PGE2 level in the blood serum. However, PGE2 level growing was insignificant. Conclusion. The presented research demonstrates the possibility of AIG treatment with the use of internal endogenous prostaglandins stimulant — rebamipide in complex with proton pump inhibitor PPI therapy.

This cluster randomized controlled trial aimed to investigate the effects of an intervention to teach resourcefulness on depression and coping style of patients with coronary heart disease (CHD). A convenience sample of 72 patients in community settings took part. Participants in the intervention group (n = 36) received an 8-week intervention based on the concept of resourcefulness, plus routine health education. Participants in the control group (n = 36) received routine health education only. After the intervention, participants in the intervention group had significantly higher scores on resourcefulness and coping styles, and lower scores on depression than those in the control group (both ps < .001). The findings suggest that a well-developed intervention to teach resourcefulness could help patients with CHD to be more resourceful, improve their level of depression, and choose more effective strategies to cope with stress.

Background: Stroke is a common cause of morbidity and mortality worldwide, and it is the third leading cause of medical death in developed countries. Stroke can be classified into ischemic disease (80%) and hemorrhagic disease (20). Subject and methods: A case-control study done in the period extending from November 2013 to April 2014 in neuro medicine department in Azadi teaching hospital in Kirkuk city in Iraq. This study involving 2 study groups, each one of them, including 50 patients. The first group (cases) included 50 patients diagnosed as having an ischemic stroke by neurologist their ages were less than 45 years .in  another group (control), 50 patients involved admitted to the same hospital with no history of prior ischemic stroke. Results: Fifty patients with stroke of ischemic orgin and 50 controls included in the study. Table 1 summarize demographic and clinical characteristics of patients and control groups, control was older than ischemic stroke patient with no significant correlation (P-value=0.33). Gender distribution showing a significant correlation in regarding female sex in both groups (P-value=0.001). Ischemic stroke according to our findings is more prevalent in those patients with Hypertension with 66% of patients in comparison to 42% of control patients with P-value of 0.0001, diabetic patients with double percentage (72%) to those in control group (36%) with P-value of 0.0001,coronary arterial disease ,valvular heart disease and rhythm disease such as atrial fibrillation seen to be more popular  in those patients with ischemic stroke with no significant value in regarding to patients having coronary and valvular heart disease (P-value=0.11,0.21) and strongly associated with those patient presented with atrial fibrillation (P-value=0.0001). Conclusion: Elevated anticardiolipin antibodies are seen to be as an independent risk factor for ischemic stroke.
