RESUMO

BACKGROUND/AIMS: We sought to identify predictors of significant tricuspid regurgitation (TR) after successful permanent pacemaker (PPM) implantation in Korean patients. METHODS: Of 404 patients who underwent PPM implantation, 187 patients who had both baseline and follow-up echocardiographic examinations were assigned to one of two groups: no development or change in TR (Group I, n = 172, 65.5 +/- 13.7 years) versus the development of significant TR (Group II, n = 15, 72.1 +/- 8.3 years). Clinical, laboratory, and echocardiographic variables were compared between the two groups. RESULTS: Overall, the grade of TR was significantly aggravated from 0.46 +/- 0.73 to 0.81 +/- 0.84 (p < 0.001) during 3.1 +/- 1.8 years of follow-up (0.49 +/- 0.75 to 0.69 +/- 0.74 in Group I, p < 0.001; 0.13 +/- 0.35 to 2.27 +/- 0.46 in Group II, p < 0.001). The de novo development or aggravation of TR was observed in 66 patients (35.3%), and significant TR developed in 15 patients (8.0%). The presence of atrial fibrillation (AF) was significantly higher (53.3 vs. 18.6%, p = 0.002), and the implantation of a ventricle pacing, ventricle sensing, inhibited by ventricular event (VVI) type pacemaker was more frequent in Group II than in Group I (46.7 vs. 15.1%, p = 0.002). Other variables were not different between the groups. CONCLUSIONS: The development or aggravation of TR was not rare after successful PPM implantation, even though the development of significant TR was uncommon. The presence of AF and the implantation of a VVI type pacemaker were predictors of the development of significant TR. Together, the results of this study suggest that the development or aggravation of TR should be monitored carefully after PPM implantation.

RESUMO

The incidence of ischemic heart disease has been increased rapidly in Korea. However, the clinical effects of antecedent hypertension on acute myocardial infarction have not been identified. We assessed the relationship between antecedent hypertension and clinical outcomes in 7,784 patients with acute myocardial infarction in the Korea Acute Myocardial Infarction Registry during one-year follow-up. Diabetes mellitus, hyperlipidemia, cerebrovascular disease, heart failure, and peripheral artery disease were more prevalent in hypertensives (n=3,775) than nonhypertensives (n=4,009). During hospitalization, hypertensive patients suffered from acute renal failure, shock, and cerebrovascular event more frequently than in nonhypertensives. During follow-up of one-year, the incidence of major adverse cardiac events was higher in hypertensives. In multi-variate adjustment, old age, Killip class > or =III, left ventricular ejection fraction <45%, systolic blood pressure <90 mmHg on admission, post procedural TIMI flow grade < or =2, female sex, and history of hypertension were independent predictors for in-hospital mortality. However antecedent hypertension was not significantly associated with one-year mortality. Hypertension at the time of acute myocardial infarction is associated with an increased rate of in-hospital mortality.
