Changes in pentraxin 3 and oxidative parameters during coronary bypass grafting and factors affecting postoperative atrial fibrillation.

OBJECTIVE: The performance of coronary bypass grafting (CBG) induces a type of subclinical systemic inflammatory response syndrome. The present study was performed to examine the changes in pentraxin 3 (PTX3) and oxidative parameters during cross-clamping in patients undergoing CBG. We also examined factors affecting the development of postoperative atrial fibrillation (POAF). METHOD: This study involved 40 patients who underwent elective on-pump CBG (33 men, 7 women; mean age, 60.8 ± 8.0 years). Blood specimens were drawn before anaesthesia and after aortic cross-clamping. POAF was detected by analysing the rhythm records of telemetry units for 96 hours postoperatively. RESULTS: The mean PTX3 concentration prior to surgery was 176.3 ± 148.4 pg/mL. After cross-clamping, it increased to 947.7 ± 377.2 pg/mL. The increase was statistically significant. Twelve patients had POAF. The leucocyte count and change in the oxidative stress index were significantly higher in patients without than with POAF. Although the increase in PTX3 was higher in patients without POAF, the difference was not statistically significant. CONCLUSION: The PTX3 concentration significantly increases during CBG. A significant change in the oxidative stress index and a more intense increase in the PTX3 concentration were seen in patients without POAF.

Is there a gender gap in secondary prevention of coronary artery disease in Turkey?

OBJECTIVE: It has been reported that women receive fewer preventive recommendations regarding pharmacological treatment, lifestyle modifications, and cardiac rehabilitation compared with men who have a similar risk profile. This study was an investigation of the impact of gender on cardiovascular risk profile and secondary prevention measures for coronary artery disease (CAD) in the Turkish population. METHODS: Statistical analyses were based on the European Action on Secondary and Primary Prevention through Intervention to Reduce Events (EUROASPIRE)-IV cross-sectional survey data obtained from 17 centers in Turkey. Male and female patients, aged 18 to 80 years, who were hospitalized for a first or recurrent coronary event (coronary artery bypass graft, percutaneous coronary intervention, acute myocardial infarction, or acute myocardial ischemia) were eligible. RESULTS: A total of 88 (19.7%) females and 358 males (80.3%) were included. At the time of the index event, the females were significantly older (p=0.003) and had received less formal education (p<0.001). Non-smoking status (p<0.001) and higher levels of depression and anxiety (both p<0.001) were more common in the female patients. At the time of the interview, conducted between 6 and 36 months after the index event, central obesity (p<0.001) and obesity (p=0.004) were significantly more common in females. LDL-C, HDL-C or HbA1c levels did not differ significantly between genders. The fasting blood glucose level was significantly higher (p=0.003) and hypertension was more common in females (p=0.001). There was no significant difference in an increase in physical activity or weight loss after the index event between genders, and there was no significant difference between genders regarding continuity of antiplatelet, statin, beta blocker or ACEi/ARB II receptor blocker usage (p>0.05). CONCLUSION: Achievement of ideal body weight, fasting blood glucose and blood pressure targets was lower in women despite similar reported medication use. This highlights the importance of the implementation of lifestyle measures and adherence to medications in women.

[EUROASPIRE-IV: European Society of Cardiology study of lifestyle, risk factors, and treatment approaches in patients with coronary artery disease: Data from Turkey]. / EUROASPIRE-IV: Avrupa Kardiyoloji Dernegi'nin koroner arter hastalarinda yasam tarzi, risk faktörleri ve tedavi yaklasimi üzerine çalismasi: Türkiye verileri.

OBJECTIVE: Data from EUROASPIRE-IV Turkey report investigating risk factors and adherence to guidelines in patients hospitalized for coronary artery disease are presented and results are compared with those of EUROASPIRE-III Turkey and EUROASPIRE-IV Europe. METHODS: Study was performed in 24 European countries, including Turkey (17 centers). Patients (18-80 years old) hospitalized for coronary (index) event during preceding 3 years were identified from hospital records and interviewed ≥6 months later. Patient information regarding index event was acquired from hospital records. Anamnesis was obtained during the interview, and physical examination and laboratory analyses were performed. RESULTS: Median age at the index coronary event was 58.8 years, and it was significantly decreased compared with last EUROASPIRE-III study (60.5 years), which was conducted at the same centers 6 years earlier (p=0.017). Of all patients, 19.3% were under 50 years of age and mean age was lower than that of EUROASPIRE-IV Europe (62.5 years). Comparing EUROASPIRE-IV Turkey with EUROASPIRE-III Turkey, rate of smokers increased to 25.5% from 23.1% (p=0.499), obesity increased to 40.7% from 35.5% (p=0.211), total cholesterol level increased to 49.6% from 48.3% (p=0.767), and diabetes rate increased to 39.7% from 33.6% (p=0.139), however none of the differences reached a level of statistical significance. Only 11.7% of the smokers quit after coronary event. Rates for these factors were lower in EUROASPIRE-IV Europe (16% for smoking, 37.6% for obesity, and 26.8% for diabetes). CONCLUSION: EUROASPIRE-IV Turkey data revealed that secondary prevention was unsatisfactory and had progressed unfavorably compared with last EUROASPIRE study, some risk factors were more uncontrolled than overall European average, and coronary artery events at young age remain an important problem.

Relationship between myocardial performance index and severity of coronary artery disease in patients with non-ST-segment elevation acute coronary syndrome.

OBJECTIVES: We aimed to investigate the relationship between myocardial performance index (MPI) and severity of coronary artery disease, as assessed by the Gensini score (GS), in patients with non-ST-segment elevation myocardial infarction (NSTEMI). METHODS: Ninety patients with an initial diagnosis of NSTEMI were enrolled in our study. They were divided into tertiles according to the GS: low GS < 19; mid GS > 19 and ≤ 96; and high GS > 96. RESULTS: The low-, mid- and high-GS groups included 24, 38 and 28 patients, respectively. Clinical features such as gender distribution; body mass index (BMI); prevalence of diabetes mellitus, hypertension and hyperlipidaemia; and smoking status were similar in the three groups. MPI and isovolumic relaxation time were significantly higher in the high-GS group than in the low- and mid-GS groups (p < 0.001 and p = 0.005, respectively). Furthermore, the high-GS group had a significantly lower ejection fraction and ejection time (p = 0.01 and p < 0.001, respectively). MPI was positively correlated with the GS (r = 0.47, p < 0.001), and multivariate regression analysis showed that MPI was an independent predictor of the GS (ß = 0.358, p < 0.001). CONCLUSIONS: Patients with NSTEMI who fall within the high-risk group may be identified by means of a simple MPI measurement.

Platelet-to-Lymphocyte Ratio Predicts Contrast-Induced Nephropathy in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome.

We assessed the relation between platelet-to-lymphocyte ratio (PLR) on admission and contrast-induced nephropathy (CIN) in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). A total of 488 patients with NSTE-ACS who underwent urgent coronary angiography were enrolled. Levels of PLR and creatinine were measured before angiography and at 72 hours after angiography. Patients were divided into 2 groups, namely, the CIN group, 80 patients (16.3%; age 65.3 ± 12.5years; 66.7% men) and the non-CIN group, 408 patients (83.7%; age 61.2 ± 12.3 years; 72.5% men). Patients in the CIN group had significantly higher PLR than those in the non-CIN group (152.9 ± 99.6 vs 120.4 ± 66.1, P < .001). In logistic regression analysis, PLR (odds ratio [OR] 1.004, 95% confidence interval [CI] 1.001-1.007, P = .02), diabetes mellitus (OR 1.75, 95% CI 1.02-2.98, P = .03), and ST-segment depression on admission electrocardiogram (OR 1.68, 95% CI 1.00-2.81, P = .04) were independent predictors of CIN. The PLR was an independent predictor of CIN after angiography in patients with NSTE-ACS.

Relationship between increased serum resistin level and severity of coronary artery disease.

Resistin, which is derived from the gene of RSTN, belongs to a family of cysteine-rich secretory proteins called resistin-like molecules (RELMs). Increased serum resistin levels are associated with coronary artery disease (CAD) and the risk of cardiovascular death. Patients (n = 214) with an initial diagnosis of stable angina pectoris, unstable angina pectoris, and myocardial infarction without ST-segment elevation and referred to catheter laboratory for coronary angiography were enrolled in the study. We aimed to investigate the relationship between increased serum resistin level and CAD. The severity of CAD was calculated by the Gensini scoring system. In conclusion, we established a significant correlation between serum resistin levels and CAD (P = .010). Also, serum resistin levels correlated with the Gensini score that represents the severity of CAD angiographically (P = .010).

Epicardial cysts: report of two rare cases.

Epicardial cysts originating directly from the epicardium are seen very rarely. Complete surgical excision is recommended when these cysts are detected. If cysts compress surrounding vital structures, cardiopulmonary bypass (CPB) should also be considered. We report herein 2 cases of multiloculated epicardial cysts, both of which were successfully excised, 1 with CPB.
