Drug Treatment Group

BackgroundCurrent guideline recommends both surgery and drug treatment for primary aldosteronism. Treatment effects on the cardiac structure and function remain under investigation.ObjectiveWe performed a prospective study in patients with primary aldosteronism to compare effects of surgery and drug treatment on the cardiac structure and function as assessed by the left ventricular (LV) pressure-strain loop, a novel echocardiographic technique that incorporates myocardial deformation and LV pressure.MethodsOur study included 39 and 28 patients treated with surgery and a mineralocorticoid antagonist, respectively. We performed conventional and speckle tracking echocardiography at baseline and 3 and 6 months of follow-up.ResultsDuring follow-up, both surgery and drug treatment normalized serum potassium concentration and significantly reduced blood pressure. Both treatments significantly and similarly decreased LV mass index and left atrial volume index. However, only in the surgery group did global wasted work significantly decrease (200.8 ± 86.7 at baseline vs. 142.1 ± 58.1 mmHg% at 6 months) and global work efficiency (91.5 ± 3.1 vs. 93.6 ± 2.3%) and global longitudinal strain (−18.3 ± 2.7 vs. −19.2 ± 1.9%) significantly (p < 0.01) increase at 6 months of follow-up. The corresponding differences from the changes in the drug treatment group were 39.5 mmHg% (95% CI, 17.1, 62.0 mmHg%), −1.64% (95% CI, −2.56, −0.71%), and −0.85% (95% CI, −1.51, −0.20%), respectively. In addition, the changes in global wasted work at 6 months of follow-up was significantly correlated with that in 24-h urinary aldosterone excretion in the drug treatment group (r = 0.54) and two groups combined (r = 0.55), but not the surgery group.ConclusionIn spite of similar serum potassium normalization and blood pressure control, surgical removal of an adrenal gland, but not mineralocorticoid receptor antagonism, showed early improvement in cardiac function.

Cross-sectional studies in athletes and untrained subjects suggest that exercise training induces adaptations in cardiac structure and function. However, the role of genetic variation on the results has largely been ignored in these studies. The purpose of this study was to investigate the effects of long-term volitionally increased physical activity on electrocardiographic and echocardiographic parameters in male monozygotic twin pairs discordant for physical activity and fitness. On the basis of the mailed questionnaires, a telephone interview, and the inclusion criteria, 12 pairs of young adult male monozygotic twins were recruited from a Finnish twin cohort. All subjects completed a maximal oxygen uptake (V̇o2 max) test and electrocardiography and echocardiography studies. Nine pairs had at least 9% difference in V̇o2 max and were selected for further analysis and for a second echocardiography study. Twins were divided into the more (MAG) and less active group (LAG), according to their V̇o2 max. On average, MAG had 18% higher V̇o2 max compared with LAG. In electrocardiography, MAG had 29% ( P = 0.02) higher Cornell voltage and 37% ( P = 0.01) higher right-side hypertrophy index. In echocardiography, no significant differences were observed between the groups, and left ventricular mass index was only 7% ( P = 0.16) higher in MAG. These results show that the volitionally increased physical activity that has led to an 18% increase in cardiorespiratory fitness induces greater changes in electro- than echocardiographic parameters. Electrocardiographic changes were suggestive of left ventricular hypertrophy, and echocardiography showed a similar but statistically nonsignificant trend.
