[The etiology and associated risk factors in a sample of 300 patients with atrial fibrillation].

PURPOSE: To analyze the etiology and the prevalence of risk factors in patients with atrial fibrillation. PATIENTS AND METHODS: Applying an unpaired case controlled study, we examined 300 consecutive patients (143 men) with atrial fibrillation and a mean age of 66 +/- 8 years. This group is compared with a control group of 700 patients (mean age 64 +/- 12 years). RESULTS: In the group with atrial fibrillation the etiology in 32% was arterial hypertension, in 20% coronary heart disease, in 13% valvular heart disease, in 11% heart failure, in 4% hyperthyroidism and in 20% idiopathic. 50% presented hypertension, 29% tobaccoism, 26% left ventricular hypertrophy, 20% consumption of alcohol, 19% hypercholesterolemia and 16% diabetes. Compared with the control group, patients with atrial fibrillation had coronary heart disease (p < 0.05), VHD (p < 0.01), myocardiopathy (p < 0.05), HT (p < 0.001), left ventricular hypertrophy (p < 0.001), diabetes (p < 0.01) and alcohol consumption (p < 0.01) more frequently. In the multivariant analysis heart failure (odds ratio 2.1 [1.2-3.3]), the valvular heart disease (odds ratio 2.2 [1.4-3.5]), the coronary heart disease (odds ratio 1.8 [1.2-2.6]), the arterial hypertension (odds ratio 1.7 [1.2-2.3]), the left ventricular hypertrophy (odds ratio 2.6 [1.7-3.8]), the diabetes (odds ratio 1.9 [1.2-2.9]) and alcoholic habits (odds ratio 2 [1.3-3.9]) were independent risk factors for atrial fibrillation in our population. CONCLUSIONS: Atrial fibrillation in our study, is more frequent in patients with arterial hypertension, coronary heart disease or valvular heart disease. There are other risk factors such as arterial hypertension, diabetes and consumption of alcohol too, the modification of which could diminish the risk of the appearance of atrial fibrillation.

[Pharmaceutical care in people who have had acute coronary episodes (TOMCOR study)].

BACKGROUND: This study evaluates the effects on coronary patients of a new practice in community pharmacies called Pharmaceutical Care (PhC) as compared to the traditional pattern of pharmacy practice. It attempts to ascertain whether pharmaceutical care is feasible in addition to ascertaining differences in effectiveness for coronary patients' pharmacotherapeutic health outcomes, potentially attributable to PhC. METHODS: A randomized prospective controlled-intervention study was conducted in 83 community pharmacies in the provinces of Asturias, Barcelona, Madrid and Biscay in a one-year monitoring of the drug-use of 735 patients at the start of the study (330 intervention patients and 405 control) and 600 at the end. RESULTS: Differences were fund in favor of the intervention group in: a) the use of health care services as a morbidity indicator such as frequency of hospital emergency room visits 1.27 I (CI95%; 1.10-1.44) and 1.63 C (CI95%; 1.36-1.90) or average length-of-stay in Intensive Care Units 2.46 I (CI95%; 1.56-3.36) and 5.87 C (CI95%; 3.57-8.17), both due to coronary causes; b) health-related quality of life score (physical functioning dimension difference of 4.7 (p < 0.05); c) average patient knowledge of coronary heart disease risk factors having improved by 10% (p < 0002-0.007 depending on dimension); d) patient knowledge of the name and identification of their drugs having improved by 10% (p < 0.001) along with their subjective perception of the antiagregans drugs relative importance having improved by 12% (p < 0.009) and effects of beta-blockers having improved by 25% (p < 0.02); e) average satisfaction with pharmaceutical care service and perception of pharmacist's professional competence having improved by 2% (p < 0.000 to 0.05 depending on dimension). CONCLUSIONS: A decrease in emergency health care demand due to coronary causes, a fewer number of patient hospitalizations and a shorter length-of-stay in Coronary Intensive Care Units due to hospitalization regarding coronary patients on pharmaceutical care would suggest that patients who suffered an acute coronary heart episode made a better use of drugs and would tend to be less ill. Furthermore, coronary patients who received pharmaceutical care services showed a better knowledge of the reasons for their pharmacotherapy and therefore took better advantage of health care resources and improved their health condition.

[Myocardial infarct in diabetes mellitus: short- and long-term prognostic factors].

To determine the evolution of acute myocardial infarction in patients with diabetes we study 207 consecutive patients with myocardial infarction. Using WHO's criteria 23% of our cases were diagnosed of diabetes mellitus. Diabetic patients were older than non diabetic (67.9 +/- 10 years vs. 62.4 +/- 11 years, p less than 0.05) and had a higher ratio of females (52% vs. 21%, p less than 0.001). Cigarette smoking was infrequent in diabetic population. Incidence of other risk factors was comparable. Despite an increased proportion on no q-wave myocardial infarction in the diabetic patients (12.5% vs. 6.9%, p NS), the site of infarction was similar into the two groups. Acute phase mortality was higher in the diabetic group (37.5% vs. 16.3%, p less than 0.001). This increased mortality is, partially, related to an increased incidence of pump failure, but a multivariate analysis using stepwise logistic regression, selected diabetes as an independent predictor of prognosis. Survivors were followed for 41 +/- 20 months; diabetic patients showed a poor prognosis with a higher incidence of congestive heart failure (42.8% vs. 13.7%, p less than 0.01), reinfarction (16.6% vs. 8.5%) and death. Cox proportional hazard model selected diabetes as an independent predictor of survival. We conclude that patients with diabetes mellitus constitute a subgroup into the myocardial infarction population; this subgroup had greater mortality than non diabetic patients in relation to increased incidence of pump failure, but multivariate analysis indicates that other factors not considered in the present study may play a role in their poor prognosis.
