[Trends of hospitalizations for chronic heart failure in Andalusia in the last decade].

BACKGROUND AND OBJECTIVES: The cost of hospitalization represents the greatest proportion of total expenditure due to heart failure. Our objective was to analyze the trends of morbidity of chronic heart failure in Andalusia between 1990-2000. MATERIAL AND METHODS: The data on hospitalizations in Andalusia (title 428 of the ninth revision of the International Disease Classification) were obtained from the National Survey of Hospital Morbidity of the National Institute of Statistics. The rates, standardized by age and gender, of admission due to heart failure were calculated by the direct standardization method. RESULTS: The absolute number of hospitalizations due to hear failure in people over 45 years was 4,345 in 1990 and 10,153 in 2000 (a relative increase of 230%) and it represents 14.2% hospitalizations in Spain. The increase was focused on those over 65 years and the standardized rates were slightly greater in women than in men. CONCLUSIONS: Hospitalization discharge rates increased mostly in the population older than 65 and women showed hospitalization rates slightly greater than men.

[Therapeutic attitude after coronariography in elderly patients with ischemic heart disease].

INTRODUCTION: The incidence of ischemic heart disease in the elderly is high. These patients are increasing referred for coronariography. OBJECTIVES: Identify factors associated with coronary revascularization in elderly patients. MATERIAL AND METHODS: Retrospective study of 473 patients > or = 75 years who underwent coronariography in relationship with ischemic heart disease. Their clinical-epidemiological characteristics and treatment adopted were analyzed. A multivariate analysis model was used to identify factors associated with revascularization. RESULTS: Mean age was 77.6 +/- 2.8 years; 70.4% were men. A total of 36% smoked, 53% were hypertensive, 33% diabetics and 30% dislipidemic. Thirty one % had multivessel disease and 11% involvement of left coronary trunk. There was evidence of anterior descending artery in 68%. Medical treatment was done in 48.4%, percutaneous revascularization in 41.5% and surgical in 10.1%. Patients with lesions of the anterior descending artery were revascularized in greater proportion: 67.7% vs 32.3%; p. 0.001. A logistic regression model was used to identify revascularization predictors, obtaining a direct relationship with the involvement of the anterior descending artery (OR: 4.87; 95% CI: 2.98-7.94; (p < 0.001) and inverse on with the previous revascularization (OR: 0.47; 95% CI: 0.26-0.85; p < 0.02), left ventricular dysfunction (OR: 0.58; 95% CI: 0.39-0.88; p = 0.01) and presence of multivessel disease (OR: 0.51; 95% CI: 0.31-0.84; p < 0.01). CONCLUSIONS: The elderly subjects with ischemic heart disease who underwent coronariography received revascularizing treatment in somewhat more than 50% of the cases. A direct relationship was found between involvement of the anterior descending artery and performance of revascularizing treatment and an inverse on between previous revascularization, left ventricular dysfunction and presence of multivessel disease.

[Creatine kinase increases after coronary interventions].

INTRODUCTION AND OBJECTIVES: Percutaneous revascularization has led to an important change in the treatment of patients with symptomatic ischemic heart disease in recent years. There is controversy concerning the incidence and prognostic significance of postprocedural increases in creatine kinase. The aim of this study was to assess the incidence of these elevations and the related factors and to observe the prognosis of patients with and without creatin kinase elevations. METHODS: We reviewed 447 patients in whom an angioplasty was done in our department from January 1997 to June 1998, excluding 138 patients with myocardial infarction in the previous four days or unsuccessful angioplasty. Creatine kinase was measured in all patients at 0, 4, 8 and 24 hours after angioplasty. We analyzed the incidence of elevated levels of creatine kinase following coronary surgery and the characteristics of the patients in comparison with a control group made up of patients who, at a similar time had undergone a similar angioplasty procedure including, a similar vessel and type of lesion, and equivalent left ventricular function but without elevated serum levels of creatine kinase. Major adverse coronary events were defined as: cardiac death, nonfatal myocardial infarction, new revascularization and unstable angina in which hospitalization was required. RESULTS: Out of 309 patients studied, an elevation in creatine kinase was observed in 24 patients (7.7%). Complications related to the procedure were found in 50% of these elevations, most of which involved side branch occlusion. There were no differences with respect to the demographical or anatomical characteristics of the lesions in the groups studied. During the follow-up of 9.5 months, complications were observed in 37.5% of the group of patients with elevated creatine kinase levels and in 20% of the control group, but this difference did not achieve statistical significance. CONCLUSIONS: Creatine kinase elevations are produced in 7.7% of the patients after coronary angioplasty. Complications related to the procedure were observed in 50% of the cases, most being side branch occlusion and no complications were seen in the remaining patients. Continuous measurement of creatine kinase after angioplasty shows a low sensitivity for detecting complications during follow-up. New, more sensitive and specific cardiac markers, such as troponin, could define this group of patients.

[Large myxoma of the right atrium].

We describe the case of a patient in whom two-dimensional echocardiography, performed due to dissociated cholestasis and jugular ingurgitation, demonstrated a huge mass in the right atrium which prolapsed in the right ventricle. Intraoperative transesophageal echocardiography was performed to further assess the dimension and characteristics of the mass and to discard the involvement of associated structures. The patient underwent a cardiopulmonary bypass surgery and the mass (12 * 5 cm) was removed without complications. Histologic examination confirmed the diagnosis of myxoma. This case is of interest because of the size of the mass, and is centered in the diagnosis following clinical suspicion due to the pattern of dissociated cholestasis and jugular ingurgitation leading to surgery to prevent the potential embolic complications.

[Heart failure as the initial cardiac manifestation of Steinert's myotonic dystrophy].

The relationship between neuromuscular diseases and the heart has been well known for many years. Cardiac lesions tend to involve the specialized conducting system. We report the case of a 36-year-old male diagnosed with Steinert's myotonic dystrophy whose initial cardiovascular symptom was heart failure and not symptoms related to alterations of the specialized conducting system.
