Background: This study aims to investigate the demographic and clinical characteristics and echocardiographic and microbiological findings of the patients as well as the outcomes of surgery undergoing surgical treatment with the diagnosis of infective endocarditis in Turkey. Methods: Between January 2005 and August 2012 116 patients (65 males, 51 females; mean age 43 +/- 16 years; range 14 to 80 years) with the diagnosis of infective endocarditis who underwent surgery in 13 tertiary university/research and education hospitals were included in this multi-center study. Demographic and clinical characteristics of the patients, and echocardiographic and microbiological findings, surgical indications and outcomes of surgery were retrospectively analyzed. Results: The most common symptom on admission and physical finding was fever. Blood cultures were negative in 35 patients (30%). Staphylococci were the most common microbiological pathogens (22%). Congestive heart failure was the most common indication for surgery in 56 patients (48%). Valve repair was performed in 12 patients (10%), valve replacement was the procedure of choice in 104 patients (90%). Thirty-three patients undergoing surgical treatment died in the postoperative period. The mortality rate was 28%. Independent predictors of surgical mortality were Class 3-4 functional capacity, elevated C-reactive protein, and renal dysfunction. Conclusion: Although complicated cases of infective endocarditis can be treated through surgery, surgical morbidity and mortality is still high.
Predictors of Mortality in Patients With Prosthetic Valve Infective Endocarditis: a Nation-Wide Multicenter Study
(Via Medica, 2013) Elbey, Mehmet Ali; Kalkan, Mehmet Emin; Akdag, Serkan; Ozbek, Kerem; Eren, Nihan Kahya; Demirtas, Sinan; Yuksel, Murat
Background: Our aim was to investigate the clinical and prognostic features of the patients with prosthetic valve endocarditis (PVE) in a multicenter nation-wide study. Methods: The present nation-wide study consisted of 75 consecutive patients with PVE treated at 13 major hospitals in Turkey from 2005 to 2012. Results: The patients who died during follow-up were significantly older than the survivors and had higher C-reactive protein (CRP), creatinine, poor NYHA functional class and large vegetations. High creatinine level (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.14-6.13), poor functional status (OR 24.5; 95% CI 3.1-196.5) and high CRP (OR 1.02; 95% CI 1.00-1.03) measured on admission were independent risk associates for in-hospital mortality Conclusions: High creatinine level, poor functional status and high CRP measured on admission were independent risk associates for in-hospital mortality, whereas a NYHA class of III/IV and high CRP reflected independent risk for stroke/mortality end point.
Turkish Adult Risk Factor Study Survey 2012: Overall and Coronary Mortality and Trends in the Prevalence of Metabolic Syndrome
(Turkish Soc Cardiology, 2013) Onat, Altan; Yuksel, Murat; Koroglu, Bayram; Gumrukcuoglu, H. Ali; Aydin, Mesut; Cakmak, H. Altug; Can, Gunay
Objectives: We aimed to analyze 1) overall and coronary mortality findings in the Turkish Adult Risk Factor (TARF) study survey 2012 and 2) the temporal trends in the prevalence of metabolic syndrome (MetS) and its distribution across seven geographic regions. Study design: Information on the mode of death was obtained from first-degree relatives and/ or health personnel of a local health office. Information collected in survivors was based on history, physical examination of the cardiovascular system and Minnesota coding of resting electrocardiograms. Results: Of 1527 participants to be surveyed, 796 were examined. Information was obtained on the health status in 502 subjects, and death was ascertained in 56 participants. Thirty deaths were attributed to coronary and cerebrovascular disease. Cumulative 22-year evaluation of participants in the age bracket 45-74 years revealed coronary mortality to be high, with 7.6 per 1000 person-years in men and 3.8 in women. Data used from 1754 identical subjects (median age 46 years initially), and examined in two periods 12 years apart, indicated an increase in the prevalence of MetS by 1.3% per aging of 1 year. Analysis across geographic regions showed a rise in the prevalence in the Mediterranean region, already having highest prevalence along with thr Southeast Anatolia, while the prevalence declined in the Marmara region and persisted to be thr lowest in the Aegean region. Conclusion: The prevalence of MetS in Turkish adults aged 40 years or over, currently standing at 53%, shows significant differences across geographic regions, being highest in the two southern regions and lowest in the Aegean region.
