    Long-term (>3 years) clinical and angiographic outcomes of coronary multilink stent implantations: a single center experience
    (Sage Journals, 2004) Sönmez, Kenan; Turan, Fikret; Gencebay, Murat; Değertekin, Muzaffer; Ekşi Duran, Nilüfer
    The ACS Multilink (ML) stent is a novel second-generation stent. The largest amount of information available on the long-term outcome of coronary stenting is based on the use of Palmaz-Schatz stents. Fewer data exist on long-term follow-up results of ML coronary stents implantations. The authors present the long-term (>3 years) clinical and angiographic follow-up results of the ACS Multilink coronary stents implanted in their institution. From May 1996 to December 1997, 125 patients underwent 133 coronary ML stent implantations. Stented vessels were as follows: 49% left anterior descending artery, 31% right coronary artery, and 20% left circumflex coronary artery. Indications for stent implantations were elective in 64%, because of suboptimal result from percutaneous transluminal coronary angioplasty (PTCA) in 26%, and bailout from PTCA in 10% of patients. The mean reference diameter of stented vessels was 3.2 ±0.2 mm. The mean percentage stenosis was 80 ±11% and 3 ±5% before and after stent implantation, respectively. Long-term clinical follow-up was completed in 75% (80 men, mean age 53 ±10 years) of the patients (either by interview or phone), and angiographic follow-up (37 ±12 months) was completed in 58% of the patients. There were no baseline clinical or angiographic differences between those angiographically followed up and the remaining patients. Angiographic restenosis (>50% diameter stenosis) was detected in 22% of stents. Target lesion revascularization was 12%, nontarget lesion revascularization was 14% in angiographically followed up patients. During the follow-up period death and new myocardial infarction occurred in 12% and 6% of patients, respectively, and survival rate was 88%. This study provides long-term follow-up results of intracoronary Multilink stent implantations for native coronary artery lesions. These data show that clinical and angiographic benefits of ML stents are comparable to those of the first-generation stents, especially to the Palmaz-Schatz stents, of which results have been reported previously. A considerable rate of nontarget lesion revascularization occurs during the follow-up period.

    Which method should be used to determine the obesity, in patients with coronary artery disease? (body mass index, waist circumference or waist-hip ratio)
    (National Library of Medicine, 2003) Sönmez, Kenan; Akçakoyun, Mustafa; Akçay, Ayhan; Demir, Demet; Ekşi Duran, Nilüfer; Gencebay, Murat; Değertekin, Muzaffer; Turan, Fikret
    Objective: To determine body mass index (BMI), waist circumference and waist-hip ratio (WHR) in cases with angiographically established coronary artery disease (CAD) and to compare the obesity degrees established according to the ranges determined by the International Guidelines Committees for BMI, waist circumference and WHR. Design: Cross-sectional, observational study. Subjects: A total of 617 consecutive cases (516 males, mean age: 57.2+/-10.8 y) with CAD who underwent their first coronary angiography between January 2000 and May 2000. Measurements: Before coronary angiography, their heights, weights, waist and hip circumferences were measured. Waist circumferences, BMI and WHRs were compared both as a whole and also within stratified groups as for sexes and age groups categorized in decades above 40 y of age. Results: Overweight cases comprised approximately half of the patients in both sexes. In males, the percentages of obese cases with respect to BMIs were 15%, while males with action level 2 waist circumferences were detected to be 20%. Obese male patients whose WHRs were >or=0.95 were found to be 51%. In female cases, corresponding percentages of obesity were estimated to be 32, 72 and 86%, respectively. Conclusion: In the same patient groups, the prevalence of obesity, defined by BMI, waist circumference and WHR, could vary three-fold. Thus, some patients may not display a diagnosis of obesity. To prevent this possibility the waist circumference is an easy method, which reflects central obesity more accurately.
