    OBJECTIVE: To evaluate pressures assessed at the aortic root as risk factors for severe atherosclerotic coronary heart disease in women with unstable angina/compatible clinical history associated with increase in cardiac enzymes (total CPK and CK-MB) 2 times greater than the standard value used in the hospital, with the absence of new Q waves on the electrocardiogram (UA/NSTEMI). METHODS: Five hundred and ninety-three female patients with clinical diagnosis of UA/NSTEMI underwent cinecoronariography from March 1993 to August 2001, and the risk factors for CHD were studied. During examination the pressures, at the aortic root, and coronary obstructions were visually assessed by 2 interventional cardiologists, and those stenosis over 70% were considered severe. RESULTS: Eight-one per cent of the population was white and 18.3% was black. Mean age was 59.2±11.2 years, and it was significantly higher in patients with severe coronary lesions: 61.9 ± 10.8 years versus 56.4 ± 10.8 years; smoking, diabetes mellitus and climacteric were more frequent in patients with CHD. The average mean arterial pressure and mean systolic blood pressure was the same in both groups, however, average left ventricle diastolic pressure (17.6 ± 8.7 x 15.1 ± 8.1, p=0.001), and aortic pulse pressure were significantly greater in patients with CHD (75.5 ± 22 x 70 ± 19, p=0.002), while average aortic diastolic pressure was significantly greater in patients without CHD (79.8 ± 16 x 75.3 ± 17.5, p=0.003). In the multivariated analysis, pulse pressure > 80 mmHg and systolic blood pressure > 165 were independently associated with severe CHD with odds ratio of 2.12 and 2.09, p<0.05, respectively. CONCLUSION: CHD is associated with increased pulse pressure and lower diastolic blood pressure in women with UA/NSTEMI. Although average systolic blood pressure has not been associated with CHD in this population, dichotomized values of pulse pressure > 80 mmHg and systolic blood pressure > 165 mmHG determined risk two times greater of severe coronary disease.

    Comparação da coronariografia de mulheres diabéticas e não-diabéticas com síndrome coronariana aguda sem supradesnivelamento de ST

    OBJECTIVE: Compare hemodynamic and angiographic patterns, as well as atherosclerotic lesion morphology, in diabetic and non-diabetic females with unstable angina or non-ST-segment-elevation myocardial infarction (UA/NSTEMI). METHODS: Two interventional cardiologists determined the presence of severe atherosclerotic lesion, defined as those > 70%; plaque morphology, according to the American Heart Association classification; collateral circulation; plus ventricular and aortic pressures. Ejection fraction was calculated by angiography or echocardiography. RESULTS: During eight and a half years, 645 coronary angiographies were performed in women with UA/NSTEMI. In the present study, 593 female patients were assessed (215 diabetic - 36%). This group differed from the non-diabetic in the following aspects: older age (61 ± 10.6 x 58.1 ± 11.4), higher prevalence of postmenopausal women and lower prevalence of the smoking habit. Severe three-vessel disease was significantly more frequent in diabetic patients (28% x 10%), as well as totally occluded vessels: 51 (23%) x 54 (14.3%), p < 0.005. Additionally, ejection fraction < 50% was more common in diabetic patients. CONCLUSION: These findings confirm the diffuse pattern of atherosclerotic disease in diabetic patients, as well a greater deterioration of ventricular function, which may be associated to the poorer prognosis seen in this population both in the short- and long-term.

    Depression: a predictor of smoking relapse in a 6-month follow-up after hospitalization for acute coronary syndrome
    (Lippincott Williams & Wilkins, 2008-02-01) Perez, Glória Heloise [UNIFESP]; Nicolau, Jose Carlos; Romano, Bellkiss Wilma; Laranjeira, Ronaldo [UNIFESP]; Dept Psychol; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)
    Objective The objective of the study was to investigate whether depression is a predictor of postdischarge smoking relapse among patients hospitalized for myocardial infarction (MI) or unstable angina (ILIA), in a smoke-free hospital.Methods Current smokers with MI or UA were interviewed while hospitalized; patients classified with major depression (MD) or no humor disorder were reinterviewed 6 months post discharge to ascertain smoking status. Potential predictors of relapse (depression; stress; anxiety; heart disease risk perception; coffee and alcohol consumption; sociodemographic, clinical, and smoking habit characteristics) were compared between those with MD (n = 268) and no humor disorder (n = 135).Results Relapsers (40.4%) were more frequently and more severely depressed, had higher anxiety and lower self-efficacy scale scores, diagnosis of UA, shorter hospitalizations, started smoking younger, made fewer attempts to quit, had a consort less often, and were more frequently at the 'precontemplation' stage of change. Multivariate analysis showed relapse-positive predictors to be MD [odds ratio (OR): 2.549; 95% confidence interval (CI): 1.519-4.275] (P<0.001); 'precontemplation' stage of change (OR: 7.798; 95% CI: 2.442-24.898) (P<0.001); previous coronary bypass graft surgery (OR: 4.062; 95% CI: 1.356-12.169) (P=0.012); and previous anxiolytic use (OR: 2.365; 95% CI: 1.095-5.107) (P=0.028). Negative predictors were diagnosis of MI (OR: 0.575; 95% CI: 0.361-0.916) (P=0.019); duration of hospitalization (OR: 0.935; 95% CI: 0.898-0.973) (P=0.001); smoking onset age (OR: 0.952; 95% CI: 0.910-0.994) (P=0.028); number of attempts to quit smoking (OR: 0.808; 95% CI: 0.678-0.964) (P=0.018); and 'action' stage of change (OR: 0.065; 95% CI: 0.008-0.532) (P= 0.010).Conclusion Depression, no motivation, shorter hospitalization, and severity of illness contributed to postdischarge resumption of smoking by patients with acute coronary syndrome, who underwent hospital-initiated smoking cessation.
