- ItemInterventional therapy of acute coronary syndromes in very old patient population and results of 2 years follow‑up(Springer, 2023) Boyraz, Bedrettin; Peker, Tezcan; Akgümüş, Alkame; Balun, Ahmet; 313898Background Research on cardiovascular treatment options and prognosis in very old age groups of patients is warranted. In our study, we evaluated and followed up on clinical conditions on admission and comorbidities of patients older than 80 years who were admitted to our hospital with acute myocardial infarction and shared our findings. Results A total of 144 patients were included in the study, with a mean age of 84.56 ± 5.01 years. No complications resulting in death or requiring surgery were observed in the patients. All-cause mortality was found to be related to heart failure, chronic pulmonary disease shock, and C-reactive protein levels. Cardiovascular mortality was correlated to heart failure, shock on admission, and C-reactive protein levels. No significant difference in mortality was observed between Non-ST elevated myocardial infarction and ST-elevation myocardial infarction. Conclusions Percutaneous coronary intervention is a safe treatment option with low complication and mortality rates in very old patients with acute coronary syndromes.
- ItemPrognostic value of the leuko-glycemic index in coronary chronic total occlusion patients(Prusa Medikal Yayıncılık, 2023) Peker, Tezcan; Özbek, Mehmet; Boyraz, Bedrettin; Aslan, Selen Filiz; Demir, Muhammed; Aslan, Burhan; 313898Objectives: Inflammation parameters are related to the prevalence and mortality of coronary artery disease (CAD). We aimed to evaluate the prognostic value of the leuko-glycemic index (LGI) and determine mortality in patients with chronic coronary total occlusion (CTO). Methods: A total of 546 patients were evaluated in the study. All-cause death was the primary endpoint. The leuko-glycemic index was calculated from the blood samples at admission and patients were divided into 3 groups according to their LGI levels. Kaplan-Meier survival curves were performed and logistic regression analyses was used for all multivariable analysis. Results: The mean age of the study population was 63.1 ± 11.1 years and 70.3% were male. Median follow-up time 58.2 ± 22.4 months. The mortality rate was 33.6% in the high LGI group and significantly higher compared to the other group. In multivariable analysis, LGI (OR: 1.05, 95% CI: 1,0-1.2; p = 0.02) and age (OR: 1.07, 95% CI: 1.04-1.11; p = 0.001) were found as predictors of all-cause death. Conclusions: The study revealed that high LGI is associated with all-cause death in CTO patients and LGI was a predictor of all-cause death.
- ItemShort-term prognostic value of the culprit-SYNTAX score in patients with acute myocardial infarction(MDPI, 2023) Peker, Tezcan; Boyraz, Bedrettin; 313898Background: The SYNergy between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery (SYNTAX) score is a scoring system that helps to decide on surgery or percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (MI), and studies are showing the prognostic value of this scoring system in both MI and coronary artery disease patients undergoing PCI. In acute coronary syndrome (ACS) patients, the infarct-related artery and the complexity of the lesions are also important in terms of mortality and morbidity. Our study aimed to determine the prognostic value of the culprit vessel’s SYNTAX score (cul-SS) in patients presenting with MI. Methods: In our study, 1284 patients presenting with MI were analyzed retrospectively. The SYNTAX scores and cul-SS of the patients were calculated. In-hospital and 30-day deaths and major complications were accepted as primary outcomes. The SYNTAX scores and cul-SS were compared in terms of predicting primary outcomes. Conclusions: Major complications were observed in 36 (2.8%) patients, death in 42 (3.3%) patients, and stent thrombosis in 24 (1.9%) patients. The area under the curves for SYNTAX and cul-SS for predicting primary outcomes is 0.64 and 0.68 (p = 0.026), respectively. Cul-SS was as successful as the SYNTAX score in predicting stent thrombosis and was superior in predicting short-term death and major complications.
- ItemThe effect of being married on heart rate variability, an indicator of autonomic dysfunction: A retrospective study(Lippincott Williams & Wilkins, 2023) Akgümüş, Alkame; Balun, Ahmet; Peker, Tezcan; Boyraz, Bedrettin; 313898Heart rate variability (HRV) is a noninvasive assessment that reflects the autonomic functions of the heart and is known to be impaired in many diseases. In our study, we aimed to investigate the relationship between HRV and being married. The study included 104 patients, between the aged 20 to 40 years were included in the study. The patients were divided into 2 groups as 53 healthy married (group 1) and 51 healthy unmarried (group 2). 24-hour rhythm Holter recordings were performed on all married and unmarried patients. Group 1 had a mean age of 32 ± 5 years and 47.2% men, and group 2 had a mean age of 30 ± 5 years and 54.9% men. Standard deviation of normal to normal (SDNN) was 150 ± 40 versus 128 ± 30 (P = .003), SDNN index was 66 ± 20 versus 56 ± 12 (P = .004), the square root of the mean of the squares of the differences of the adjacent root mean square of successive differences (RMSSD) was 37 ± 10 versus 30 ± 10 (P < .001), percentage of successive R-R intervals that differ by more than 50 milliseconds (PNN50) was 13.5 ± 7 versus 8.5 ± 7 (P = .001), HF was 450 ± 270 versus 225 ± 130 (P < .001) found to be significantly less in the group 2. LF/HF ratio was 1.68 ± 0.65 versus 3.31 ± 1.56 (P < .001) found to be significantly higher in the group 2. In our study, it is possible to say that the sympathetic system effect on the heart was more dominant and the HRV was lower in the unmarried group.
- ItemThe role of advanced glycation end-product levels measured by skin autofluorescence in the development of mitral annular calcification(MDPI, 2023) Boyraz, Bedrettin; Peker, Tezcan; 313898As a person ages, mitral annular calcification develops in the mitral annulus with increasing frequency. Lipid deposition, inflammation, and aging-related degeneration have been cited as potential causes of this pathophysiology, though there is currently no conclusive evidence to support this. AGEs accumulate in tissues due to the glycation of proteins and lipids, increasing the release of proinflammatory cytokines secondary to oxidative stress through the AGE receptor. The AGE levels increase in diabetic microvascular complications and degenerative aortic valve disease. Our study was planned prospectively as a case–control study involving 94 MAC-positive patients and 94 MAC-negative patients. The demographics, echocardiographic data and AGE levels of the patients were measured and recorded using the skin autofluorescence method. AGE levels were significantly higher in the MAC-positive patient group (3.2 vs. 2.7; p < 0.001). The AGE levels were observed as an independent predictor of MAC development in a regression analysis (OR: 8.05, 95% CI: 3.74–17.33, p < 0.001). In a ROC-curve analysis, the AUC was 0.79 (95% CI: 0.72–0.85). At a cut-off value of 2.7, 79.7% sensitivity and 69.1% specificity were observed. AGE levels can be used to cheaply, easily and non-invasively identify patients at risk of developing MAC.
