Gender disparity in 48-hour mortality is limited to emergency percutaneous coronary intervention for ST-elevation myocardial infarction.

BACKGROUND: Previous studies indicate that mortality from acute coronary syndromes is higher in women than in men, especially in case of interventional strategy. AIM: To assess whether the in-hospital mortality rate differs between genders during the first 48h after emergency percutaneous coronary intervention for ST-elevation myocardial infarction (emergency PCI-STEMI) or after non-emergency PCI. METHODS: All patients treated with PCI between January 2005 and June 2008 were included. The primary endpoint was frequency of death within 48h after the PCI procedure; secondary endpoints included frequency of recurrent myocardial infarction, new PCI or coronary artery bypass graft surgery, stroke, and major vascular or renal complications. Data were analysed via logistic regression with and without propensity-score matching. RESULTS: More than 9000 patients underwent PCI. In the emergency PCI-STEMI group (n=1753), 48-hour mortality occurred in 2.2% of men and 4.9% of women (p=0.004). However, gender disparity occurred only in elderly patients; the rate was significantly (p=0.02) higher in women (8.1%) than in men (3.3%) aged > or =75 years. There was no evidence of gender disparity in the non-emergency PCI group (n=7336) or in secondary endpoints for either PCI group. Similar results were obtained in pair analyses of men and women with matching propensity scores. CONCLUSIONS: Elderly women have a disproportionately high in-hospital mortality rate during the first 48h after emergency PCI for treatment of STEMI; however, there is no gender discrepancy in younger patients or patients of any age who receive non-emergency procedures.

Clinical assessment of ischemia-modified albumin and heart fatty acid-binding protein in the early diagnosis of non-ST-elevation acute coronary syndrome in the emergency department.

OBJECTIVES: Heart fatty acid-binding protein (h-FABP) and ischemia-modified albumin (IMA) have recently been evaluated, but to the best of our knowledge, no study has reported an analysis of these two markers for the detection of early myocardial infarction and myocardial ischemia in a large cohort of consecutive patients presenting to an emergency department (ED). This study evaluates the diagnostic accuracy and the clinical utility of h-FABP and IMA for non-ST-segment elevation acute coronary syndrome (ACS) diagnosis in the first hour of management in an ED. METHODS: In a prospective 11-month study, 677 patients admitted to the ED with chest pain and suspected non-ST-segment elevation ACS were enrolled. On presentation, blood samples were obtained for the measurement of the biomarkers h-FABP (immunodetection with CardioDetect) and IMA (albumin cobalt-binding test). Two physicians, blinded to the results of the markers, independently categorized patients as having or not having non-ST-segment elevation ACS. RESULTS: Of the 677 patients who were prospectively recruited, non-ST-segment elevation ACS was diagnosed in 185 (27.3%). While IMA was not predictive of the ACS diagnosis (odds ratio [OR] = 1.23; 95% CI = 0.87 to 1.81), h-FABP was predictive of ACS diagnosis (OR = 4.65; 95% CI = 2.39 to 9.04) with specificity at 96.8% (95% CI = 95.4% to 98.1%) and sensitivity at 13.5% (95% CI = 10.9% to 16.1%). However, h-FABP did not add significant additional information to a predictive model that included the usual diagnostic tools for non-ST-elevation ACS management (p = 0.40). CONCLUSIONS: In this study on a large cohort of patients admitted to an ED for chest pain, IMA and h-FABP did not provide valuable information for ACS diagnosis.

Consensus of the French Society of Gerontology and Geriatrics and the French Society of Cardiology for the management of coronary artery disease in older adults.

Coronary heart disease is a common and serious condition in patients aged over 80 years. The presenting clinical symptoms are all the more atypical and the prognosis poorer when it occurs in patients with multiple comorbid diseases. The presence of comorbidities dictates the need for a standardized geriatric assessment to screen for the existence of underlying frailty. The available scientific data were obtained during studies that included few subjects aged over 80 years. These recommendations are therefore mainly extrapolated from results obtained in younger populations. The pharmacological management and revascularization strategy for coronary heart disease in octogenarians is basically the same as in younger subjects. Epidemiological studies all concur that available therapies are underutilized despite the fact that this population has a high cardiovascular risk. Specific precautions for use must be respected because of the comorbidities and age-related changes in pharmacokinetics or pharmacodynamics. Generally, the therapeutic strategy in coronary heart disease is based not on the patient's real age, but rather on an individual analysis taking into account the severity of the coronary disease, comorbidities, the risk of drug misadventures, patient life expectancy and quality of life.

Factors predictive for in-hospital mortality following percutaneous coronary intervention.

BACKGROUND: Despite advances in procedures for percutaneous coronary intervention (PCI) and enhancement of materials and adjunctive therapy, postprocedural mortality remains a possible adverse outcome after PCI. AIMS: To assess factors independently associated with in-hospital mortality in patients referred for PCI. METHODS: Between January 2004 and December 2005, 4074 PCI were performed in our University Hospital, with 70 deaths registered either during the procedure or during the in-hospital stay. The 70 patients who died were age- and sex-matched with 70 controls in a case-control design study. Clinical and angiographic characteristics at hospital admission were collected from the patients' medical files. RESULTS: The cumulative incidence rate for in-hospital mortality was 1.72%. Variables positively and significantly associated with in-hospital mortality were severe renal failure (55.7% in cases versus 12.9% in controls, p<0.0001), cardiac failure (26.1% versus 10.1%, p=0.01), ST-segment elevation myocardial infarction (STEMI) (70.6% versus 31.4%, p<0.0001), proximal coronary lesion (72.9% versus 40.0%, p<0.0001) and angiographically visible thrombus (14.3% versus 4.3%, p=0.04). Conversely, history of coronary heart disease, smoking and dyslipidemia were less frequent among cases. In multivariable analysis, the adjusted odds ratios (OR) for in-hospital death were 4.89 (95% confidence interval [CI] 1.96-12.2, p<0.001) in STEMI versus non-STEMI, 4.28 (95% CI 1.73-10.6, p<0.01) in those with a proximal coronary lesion, and 9.77 (95% CI 3.42-27.9, p<0.0001) in patients with severe renal failure. CONCLUSION: STEMI, proximal coronary lesion, and renal failure at admission are identified as particular settings associated with a higher probability of in-hospital mortality after PCI.

Are there specific prognostic factors for acute coronary syndrome in patients over 80 years of age?

PURPOSE: In elderly patients, the prognosis of acute coronary syndrome is bleak and the impact of geriatric factors is as yet unknown. The purpose of this work was to identify factors predictive of poor outcome at Month 6 in a population of elderly subjects admitted into hospital with acute coronary syndrome. MATERIALS AND METHODS: One hundred and thirty-two patients over 80 years of age were compared with 127 patients under 80, all admitted into a cardiology intensive care unit with acute coronary syndrome between May 2006 and January 2007, vis-à-vis outcome, mortality and cardiovascular events, both during the hospital stay and six months later. RESULTS: Coronary angiography was performed in fewer of the over-80 group (85.6% versus 97.7%, p<0.001) but revascularisation rates were comparable in both groups (75.6% versus 78.9%, p=0.58). During the hospital stay, the incidence of complications was higher (68.8% versus 38.1%, p<0.0001) in the older patients as was mortality (18.2% versus 3.2%, p=0.0001). At Month 6, all-cause mortality was higher in the octogenarians (28.0% versus 10.6%, p<0.001). The independent variables associated with Month 6 all-cause mortality in the over-80 group were: systolic blood pressure of less than 100mmHg, an admission heart rate of over 100bpm, a history of cardiovascular disease, acute coronary syndrome with ST segment elevation in the anterior territory, and the absence of chest pain. CONCLUSION: In elderly patients admitted into hospital with acute coronary syndrome, geriatric parameters do not seem to affect prognosis which is dominated by cardiac variables.

Resumption of atrioventricular conduction by levosimendan after radiofrequency ablation of the AV node:.

We report the case of a patient in whom radiofrequency catheter ablation of the AV node was initially successfully performed for persistent atrial fibrillation with fast ventricular rate, but in whom atrioventricular conduction transiently resumes following therapy with levosimendan. Plausible hypothesis are discussed as well as potential implications.

Mediastinal lymphadenopathy in congestive heart failure: a sequential CT evaluation with clinical and echocardiographic correlations.

The aim of this study was to evaluate the frequency and evolution after treatment of mediastinal lymphadenopathy associated with congestive left heart failure on CT scans in correlation with clinical and echocardiographic findings. Thirty-one consecutive patients with subacute left heart failure underwent a clinical evaluation using the NYHA classification, a CT examination, and transthoracic echocardiography at the time of initial presentation (T1). After initiation of medical treatment (T2), follow-up CT scans were systematically obtained together with a clinical evaluation. At T1, all patients showed severe (type III: n=12, 39%; type IV: n=12, 39%) to moderate (type I, n=1, 3%; type II, n=6, 19%) dyspnea with a mean ejection fraction of 39% (range 22-74%). On initial CT scans, enlarged mediastinal lymph nodes were seen in 13 patients (42%) with blurred contours in 5 patients (16%) and hazy mediastinal fat in 1 patient (3%). Significant decrease in the size of lymphadenopathy was observed between T1 and T2 (T1, n=13, 42% vs T2, n=10, 32%; p<0.05) with a concurrent decrease in the severity of dyspnea (grade III-IV dyspnea at T1, n=24, 78% vs grade I-II dyspnea at T2, n=26, 83.5%). Patients with enlarged lymph nodes at T1 showed: (a) a significantly lower ejection fraction at echocardiography than those without lymphadenopathy (mean+/-SD value: 34+/-12.9 vs 43+/-13.8%; p=0.04); (b) a significantly larger diameter of the right superior pulmonary vein (mean+/-SD value: 17+/-2.75 vs 14+/-3.9 mm; p=0.04); and (c) a higher frequency of abnormal peribronchovascular thickening ( n=5 vs n=1; p=0.06). Mediastinal lymphadenopathy associated with subacute left heart failure was observed in 13 patients (42%), showing regression after initiation of treatment in 8 of 13 patients (62%).
