RESUMO

OBJECTIVES: This study sought to assess preclinical cardiac abnormalities in chronic alcoholic patients and possible differences among alcoholics related to the duration of heavy drinking. BACKGROUND: Chronic excessive alcohol intake has been reported as a possible cause of dilated cardiomyopathy. However, before the appearance of severe cardiac dysfunction, subtle signs of cardiac abnormalities may be identified. METHODS: We studied 30 healthy subjects (age 44 +/- 8 years) and 89 asymptomatic alcoholics (age 45 +/- 8 years, p = NS) divided into three groups, with short (S, 5-9 years, n = 31), intermediate (I, 10-15 years, n = 31) and long (L, 16-28 years, n = 27) duration of alcoholism. Transmitral early (E) and late (A) Doppler flow velocities, E/A ratio, deceleration time of E (DT) and isovolumic relaxation time (IVRT) were obtained. Left ventricular (LV) wall thickness and volumes were also determined by echocardiography, and LV mass and ejection fraction (EF) were calculated. RESULTS: The alcoholics had prolonged IVRT (92 +/- 11 vs. 83 +/- 7 ms, p < 0.001), longer DT (180 +/- 20 vs. 170 +/- 10 ms, p < 0.01), smaller E/A (1.25 +/- 0.34 vs. 1.40 +/- 0.32, p < 0.05), larger LV volumes (73 +/- 8 vs. 65 +/- 7 ml/m2, p < 0.001 for end-diastolic volume index; 25 +/- 4 vs. 21 +/- 2 ml/m2, p < 0.001 for end-systolic volume index), higher LV mass index (92 +/- 14 vs. 78 +/- 8 g/m2, p < 0.001) and thicker posterior wall (9 +/- 1 vs. 8 +/- 1 mm, p < 0.001). Ejection fraction did not differ between the two groups (66 +/- 4 vs. 67 +/- 2%). Deceleration time of the early transmitral flow velocity was longer in groups L (187 +/- 18 ms) and I (185 +/- 16 ms) compared with group S (168 +/- 17 ms, p < 0.001 for L and I vs. S), whereas A was higher in group L compared with S (43 +/- 10 vs. 51 +/- 10 cm/s, p < 0.005). Multiple regression analysis identified duration of heavy drinking as the most important variable affecting DT and A. CONCLUSIONS: Left ventricular dilation with preserved EF and impaired LV relaxation characterized LV function in chronic asymptomatic alcoholic patients. It appeared that the progression of abnormalities in LV diastolic filling related to the duration of alcoholism.

RESUMO

PURPOSE: The reported incidence of cardiac involvement in trichinosis is highly variable, ranging from 21% to 75%. This study sought to determine the incidence and type of cardiac lesions in trichinosis using serial echocardiographic examinations. SUBJECTS AND METHODS: Sixty-two consecutive patients admitted to the Banja Luka Medical Center during an outbreak of trichinosis (November to December 1996) were included in the study. Diagnosis was made by typical clinical presentation, positive epidemiologic history, serologic testing, and the detection of Trichinella larvae in contaminated meat. All patients underwent serial electrocardiograms and two-dimensional and Doppler echocardiographic examinations within 20 days after the onset of symptoms. Repeated echocardiographic examinations were performed weekly during the hospital stay in all patients with electrocardiographic abnormalities or an abnormal initial echocardiogram. RESULTS: Cardiac involvement (electrocardiographic and/or echocardiographic changes) was detected in 8 (13%) of the 62 patients. Nonspecific transient electrocardiographic ST-T changes were found in 6 patients (10%); 1 patient had frequent premature ventricular complexes. Echocardiographic examinations revealed pericardial effusions in 6 patients (10%), 5 of whom had minimal effusions without impairment of global and regional left ventricular systolic function. One patient had hypokinesis of the interventricular septum with a small pericardial effusion, both of which resolved within 2 weeks. Only 2 of the patients with electrocardiographic abnormalities lacked echocardiographic evidence of cardiac involvement. At 6-month follow-up, none of the patients had electrocardiographic or echocardiographic abnormalities. CONCLUSIONS: The incidence of cardiac involvement in trichinosis appears to be lower than previously reported. Pericardial effusion is the most common manifestation of cardiac involvement, and nonspecific transient electrocardiographic changes, traditionally ascribed to myocarditis, more frequently reflect pericarditis.
