The effect of post-discharge educational intervention on patients in achieving objectives in modifiable risk factors six months after discharge following an episode of acute coronary syndrome, (CAM-2 Project): a randomized controlled trial.

OBJECTIVES: We investigated whether an intervention mainly consisting of a signed agreement between patient and physician on the objectives to be reached, improves reaching these secondary prevention objectives in modifiable cardiovascular risk factors six-months after discharge following an acute coronary syndrome. BACKGROUND: There is room to improve mid-term adherence to clinical guidelines' recommendations in coronary heart disease secondary prevention, specially non-pharmacological ones, often neglected. METHODS: In CAM-2, patients discharged after an acute coronary syndrome were randomly assigned to the intervention or the usual care group. The primary outcome was reaching therapeutic objectives in various secondary prevention variables: smoking, obesity, blood lipids, blood pressure control, exercise and taking of medication. RESULTS: 1757 patients were recruited in 64 hospitals and 1510 (762 in the intervention and 748 in the control group) attended the six-months follow-up visit. After adjustment for potentially important variables, there were, between the intervention and control group, differences in the mean reduction of body mass index (0.5 vs. 0.2; p < 0.001) and waist circumference (1.6 cm vs. 0.6 cm; p = 0.05), proportion of patients who exercise regularly and those with total cholesterol below 175 mg/dl (64.7% vs. 56.5%; p = 0.001). The reported intake of medications was high in both groups for all the drugs considered with no differences except for statins (98.1% vs. 95.9%; p = 0.029). CONCLUSIONS: At least in the short term, lifestyle changes among coronary heart disease patients are achievable by intensifying the responsibility of the patient himself by means of a simple and feasible intervention.

[Cardiac hamartoma. Case report and literature review]. / Hamartoma intracardíaco. Caso clínico y revisión de la bibliografía.

Primary cardiac tumors are infrequent and usually benign. They can manifest as dyspnea, chest pain, palpitations, sudden death, peripheral embolism, cyanosis, or general symptoms. They are sometimes an incidental finding in an asymptomatic patient. We describe a 33-year-old man who was seen because of dyspnea and palpitations. Transthoracic echocardiography revealed, on the lateral wall of the left ventricle, an intramyocardial mass that was successfully resected surgically. The pathologic diagnosis was hamartoma of mature cardiac myocytes. We discuss the usefulness of imaging techniques for identifying cardiac masses.

INTRODUCTION AND OBJECTIVES: Adherence to established guidelines for patients discharged from the hospital after acute coronary syndrome is known to be suboptimal. The aim of this study was to assess the efficacy of a program for physicians centered on the treatment of acute coronary syndrome. PATIENTS AND METHOD: 39 hospitals participated. INTERVENTION: a set of measures was developed by consensus for the creation and distribution of educational materials. OUTCOMES OF INTEREST: Proportion of patients in whom ejection fraction and residual ischemia were evaluated, treatment at discharge, and health and dietary recommendations to patients (smoking, diet, exercise, etc.) referred to all patients in whom these measures or treatments should have been used ("ideal patients"). Changes were assessed with four cross-sectional surveys. RESULTS: A total of 1157, 1162, 1149 and 1158 patients were included. There were no relevant differences between these groups in baseline characteristics. In general, there was improvement in all variables between the first and the last survey. The proportion of patients who were weighed and measured increased (from 33.5% to 53.4%; P<.0001), as did the proportion of those in whom cholesterol was measured early (42.6 to 53.7%; P=.006). The proportion in whom residual ischemia was not measured despite indications for this test decreased (18.2% to 10.8%; P=.013), and the proportion increased for appropriate treatment with statins on discharge (68.6% to 81.4%; P<.0001), advice to quit smoking (60.1% to 72.2%; P<.0001) and advice to exercise (58.3% to 67.4%; P=.003). CONCLUSIONS: The educational intervention seems to have had a positive effect on improving the appropriateness of procedures and treatments for patients discharged after acute coronary syndrome.

Expression of activation molecules in neutrophils, monocytes and lymphocytes from patients with unstable angina treated with stent implantation.

Coronary angioplasty is known to mediate an inflammatory response. Recently, we have characterized the transient systemic inflammatory response after coronary stent implantation in patients with unstable angina by measuring different soluble protein markers. In the present study we have characterized the expression of various cellular activation markers in neutrophils, monocytes and lymphocytes from the same group of patients. Peripheral blood samples were taken before and 24 h, 48 h and 7 days after successful coronary stenting in 58 patients. Cell surface markers (CD11b/CD18 and CD38) were analyzed by flow cytometry to determine the activation of neutrophils, monocytes and T lymphocytes. We found that coronary angioplasty with stent implantation produces an increase in the cell surface expression of CD11b/CD18 in neutrophils and CD38 in monocytes, following a similar time-course with a peak after 24 h, returning to basal levels after 48 h and a second peak after 7 days. However, T lymphocytes were not found to be activated. These results suggest that coronary stent implantation induces a different pattern inducing soluble and cellular inflammation markers, and therefore, they should be taken into account in patients undergoing stent implantation to study clinical correlations.

Inflammatory response to coronary stent implantation in patients with unstable angina.

Previous evidence has shown that coronary angioplasty leads to the release of inflammatory mediators. In this study, we sought to characterize the systemic inflammatory response after coronary stent implantation in patients with unstable angina by measuring different protein markers. Peripheral blood samples were taken before and 24 h, 48 h, and 7 days after successful coronary stenting in 58 patients. Several markers of acute-phase response were determined: C-reactive protein (CRP), alpha2-macroglobulin, haptoglobin, acid alpha1-glycoprotein, prealbumin and albumin. Besides, proinflammatory cytokines (tumor necrosis factor-alpha, IL-6, IL-8) and the anti-inflammatory cytokine IL-10 were also measured. We have found that coronary angioplasty with stent implantation produces a systemic inflammatory response with a rise in inflammation markers concentration. CRP plasma levels declined 1 week after the intervention, but the other marker levels were even higher after 7 days. IL-6 was the only cytokine whose plasma levels significantly increased in peripheral blood after stenting, with a rise after 24 h, maintained after 48 h, and decreased to near-basal levels after 1 week. There was a good correlation between CRP and IL-6 plasma levels (r=0.5, p<0.001). IL-10 levels were slightly decreased after 24 h. Although no significant differences in the means at different time points were found, there was a decrease in IL-10 in most patients 24 h after the intervention. These results indicate that coronary stent implantation induces a systemic inflammatory reaction, with a temporal increase in the concentration of the inflammation markers, especially CRP and IL-6. Since these markers had been previously used as prognostic markers, this needs to be taken into account in patients undergoing stent implantation.
