Significant Difference

Background It is still not clear whether hypertension and left ventricular hypertrophy (LVH) are more common in continuous ambulatory peritoneal dialysis (CAPD) than in hemodialysis (HD) patients. Methods To examine this subject, the indices of cardiac performance were compared between 50 HD and 34 CAPD patients. Patients were further divided into two subgroups [long-term (L) CAPD and L-HD] according to dialysis modality and duration of dialysis (more than 60 months’ duration). Results The blood pressure and cardiothoracic index of CAPD patients did not differ from HD patients. On average, the left atrial index was 2 mm/m2 higher in HD patients than in CAPD patients. Left ventricular chamber sizes, wall thickness, and left ventricular mass index (LVMI) in patients on CAPD were similar to those of HD patients. Isovolumic relaxation time (IVRT) of CAPD patients was insignificantly less than that of HD patients (101 ± 22 and 115 ± 27 msec respectively). There was no significant difference between the two subgroups (L-HD and L-CAPD) in blood pressure, left atrial diameter, left ventricular chamber size, wall thickness, LVMI, ejection fraction, or IVRT. Conclusion If normovolemia and normotension are obtained by strict volume control without using antihypertensive drugs, the effects of the two modalities of chronic dialysis treatment (HD and CAPD) on cardiac structure and function are not different from each other.

Remodeling Index

Abstract Funding Acknowledgements National Medical Research Council BACKGROUND Hypertensive left ventricular hypertrophy (LVH) is associated with increased cardiovascular events. The authors previously developed the Remodeling Index (RI) that incorporated LV volume and wall-thickness in a single measure of advanced hypertrophy in hypertensive patients. PURPOSE This study examined the mechanisms and prognostic potential of the RI in reference with current LVH classifications. METHODS Cardiovascular magnetic resonance (CMR) was performed in 400 asymptomatic hypertensive patients. The newly derived RI ([(EDV)^1/3]/t; where EDV is LV end-diastolic volume and t is the maximal wall thickness across 16 myocardial segments) stratified hypertensive patients into 3 groups: without LVH, LVH with normal RI (LVH_Normal-RI) and LVH with low RI (LVH_Low-RI). The primary outcome was a composite of all-cause mortality, acute coronary syndromes, strokes and decompensated heart failure. RESULTS LVH_Low-RI was associated with increased LV mass index, fibrosis burden, impaired myocardial function and elevated biochemical markers of myocardial injury and wall stress. Over 18.3 ± 7.0 months (601.3 patient-years), patients with LVH_Low-RI had more than a 5-fold increase in adverse events compared to those with LVH_Normal-RI (11.6 events/100patient-years versus 2.0 events/100 patient-years, respectively; log-rank P < 0.001; Figure A). The RI provided incremental prognostic value over and above a model consisting of clinical variables and LVH (P = 0.02). Conversely concentric and eccentric LVH were associated with adverse prognosis (4.5 events/100patient-years versus 6.0 events/100patient-years, respectively; log-rank P = 0.62) that was similar as the natural history of hypertensive LVH (5.1 events/100patient-years). CONCLUSIONS The RI provides mechanistic insights and prognostic value that improves risk-stratification of hypertensive LVH. Abstract P962 Figure.

Percutaneous Septal Ablation

We present an HOCM patient in whom marked regression of left ventricular hypertrophy occurred within two years following outflow desobliteration by percutaneous septal ablation. Maximum wall thickness (initially documented by both echo and MRI) decreased from 34 mm to 22 mm (followup by echo only due to presence of the ICD), crossing the threshold value of 30 mm which was one of the risk markers that had triggered the primary prophylactic ICD implantation in this case prior to septal ablation.
