The poor long-term outcome in young diabetic patients receiving stents is not well understood. The purpose of this study was to characterize the pastprocedural results of stent placement in diabetic patients using intravascular ultrasound to identify factors that might be associated with poor clinical outcome. The acute dimensions from intravascular ultrasound studies after stent deployment at 5 sites were measured from 39 coronary segments from patients with diabetes mellitus (DM) and 161 segments from nondiabetic patients (non-DM). Within these 2 groups, segments were subgrouped into young (y) and old (o) in reference to the mean study age of 64 years, forming 4 groups: yDM (n = 20), y non-DM (n = 65), oDM (n = 19), and o non-DM (n = 96). Results are reported as mean +/- 1 SD. Diabetic patients had smaller mean lumen area within the treated segment than o non-DM (8.37+/-2.59 vs. 9.11+/-3.35 mm2, p<0.01). These differences were more pronounced at the distal reference vessel lumen of yDM than y non-DM (7.6+/-2.3 vs. 10.3+/-4.5 mm2, p<0.003), and were associated with greater percent plaque area in the distal reference vessel (43.4+/-13% vs. 34.1+/-11.2%, p<0.003). In young diabetic patients undergoing elective stent placement, underexpansion of the stented segment is common, which may contribute to the relatively poor long-term outcome in these patients. We suggest that when stenting is the procedure of choice in this subgroup of high-risk patients, special attention should be given to optimizing lumen dimensions. [ABSTRACT FROM AUTHOR]

The ability to provide an accurate prognosis in an intensive care unit is of major importance. Numerous risk scores have been developed to predict hospital mortality based on demographic, physiologic, and clinical data. These scores were universally developed in general medical or surgical intensive care units. Patients admitted to a cardiac care unit differ in many aspects from those admitted to general medical intensive care units. Few patients require mechanical ventilation and prolonged intensive care. Performance of risk scores developed for patients with acute myocardial infarction (AMI) in this subgroup is unknown. We prospectively studied 51 consecutive patients who were admitted to a cardiac care unit from September 2006 to March 2008 for AMI and received mechanical ventilation for >24 hours. Acute Physiology and Chronic Health Evaluation II (APACHE II), Thrombolysis In Myocardial Infarction, and Global Registry of Acute Coronary Events risk scores were calculated for each patient. Mortality rates were extrapolated based on these 3 risk scores. Twenty-two of 51 patients (43%) died in hospital. Age, mean arterial pressure, urea, albumin, hemoglobin, need for vasopressors, and estimated glomerular filtration rate were predictive of mortality. APACHE II and Global Registry of Acute Coronary Events scores were higher in nonsurvivors but Thrombolysis In Myocardial Infarction risk score was not predictive of mortality. APACHE II score had the highest value for area under receiver operator characteristics curve for mortality prediction. In conclusion, patients with AMI requiring mechanical ventilation have a high mortality rate. This risk is predicted by co-morbidities better than by direct cardiac parameters. Consequently, conventional AMI risk scores do not perform well in this very sick population and the APACHE II score better predicts their short-term outcome. [ABSTRACT FROM AUTHOR]

The incidence and clinical correlates of acute in-hospital mortality of takotsubo cardiomyopathy (TTC) are not clear. We performed a systematic review and meta-analysis to consolidate the current evidence on acute mortality in TTC.We then assessed the impact of "secondary" TTC, male gender, advancing age, and catecholamine use on mortality. A comprehensive search of 4 major databases (EMBASE, Ovid MEDLINE, PubMed, and Google Scholar) was performed from their inception to the first week of July 2013. We included original research studies, recruiting ‡10 participants, published in English language, and those that reported data on mortality and cause of death in patients with TTC. Of 382 citations, 37 studies (2,120 patients with TTC) from 11 different countries were included in the analyses. The mean age of the cohort was 68 years (95% confidence interval [CI] 67 to 69) with female predominance (87%). The in-hospital mortality rate among patients with TTC was 4.5% (95% CI 3.1 to 6.2, I² = 60.8%). Among all deaths, 38% were directly related to TTC complications and rest to underlying noncardiac conditions. Male gender was associated with higher TTC mortality rate (odds ratio 2.6, 95% CI 1.5 to 4.6, p = 0.0008, I² = 0%) so was "secondary" TTC (risk difference -0.11, 95% CI -0.18 to L0.04, p = 0.003, I² = 84%). The mean age of patients dying tended to be greater than that in the whole cohort (72 ± 7 vs 65 ± 7 years). In conclusion, TTC is not as benign as once thought. To reduce the mortality rate, greater efforts need to be directed to the diagnosis, treatment, and ultimately prevention of "secondary" TTC. [ABSTRACT FROM AUTHOR]

Coronary artery perforation (CP) is a rare, sometimes lethal complication of percutaneous coronary intervention. There are limited controlled contemporary data regarding its predictors, incidence, and outcomes. The aim of this study was to define the incidence, associated factors, and outcomes of CP in the current era of coronary intervention. All patients who had CP during percutaneous coronary intervention at a large tertiary center from January 2001 to December 2008 were identified. Demographic, clinical, and procedural data and outcome variables were obtained. Patients with CP were compared with a randomly assigned control group. Fifty-seven patients with CP were identified among 9,568 interventions performed during the study period (0.59%); these patients were compared with 171 who underwent percutaneous coronary intervention without CP. Vessels were perforated by wires (52.6%), balloons (26.3%), and stents (21.1%). Perforations were classified using the Ellis classification. CP was associated with mortality and tamponade rates of 7% and 16%, respectively, but all these serious complications occurred with grade III perforations. Most grade I and II perforations were managed conservatively. Multivariate analysis identified the treatment of chronic total occlusion as the strongest independent predictor of CP; other independent variables included calcium in the coronary artery that was the site of intervention and non–ST elevation myocardial infarction.

Patients with acute coronary syndromes (ACSs) may develop serious multiorgan complications and require prolonged intensive care. Our aim was to characterize and identify factors that are associated with outcomes in these patients. We retrospectively identified 267 consecutive patients admitted to the coronary care unit for an ACS who required >3 days of mechanical ventilation. Multiple clinical and laboratory variables were correlated with mortality. Patients’ ages were 68.3 ± 10.9 years (mean ± SD) and 165 (62%) were men. Seventy-six patients (29%) died within 30 days of admission, and the 1 year mortality was 46%. Moderate or severe left ventricular systolic dysfunction was found in 72% of the patients. Eighty-nine patients (33.3%) required vasopressors, of whom 64 (72%) did not survive 30 days. Among 127 patients who required antibiotics (48.3%), 30-day mortality was 53% compared with 4% among patients who did not require antibiotics (p <0.001). The 30-day mortality among patients who received both antibiotics and vasopressors was 64 of 87 patients (74%), and the 1-year mortality in this subgroup was 86.2%. Parameters found to be independent predictors of 30-day mortality were (in descending order): vasopressor requirement, use of antibiotics, peripheral vascular disease, ST-elevation myocardial infarction, renal failure, obesity and Killip class on admission. In conclusion, mortality among patients who require prolonged mechanical ventilation after an ACS is substantial. The main independent predictors of with mortality are the severity of heart failure and the presence of co-morbidities. [Copyright &y& Elsevier]

BACTEREMIA , *SEPSIS , *INTRA-aortic balloon counterpulsation - Abstract
In this prospective study, a significant incidence of fever (47%), true bacteremia (15%), and sepsis (12%), were found in 60 cardiac patients treated with an intra-aortic balloon counterpulsation pump. The benefit of antibiotic prophylaxis in this setting should therefore be evaluated. [ABSTRACT FROM AUTHOR]
