Abstract 15779: Quality of Life in a Cohort of Familial Hypercholesterolemia Patients Undergoing Molecular Cascade Screening in Brazil
Introduction:: Familial hypercholesterolemia (FH) is an underdiagnosed and undertreated disease associated with elevated risk of early cardiovascular disease (CVD) and thus can reduce quality of life. The present health related quality of life (HRQL) investigation, evaluated patients personal interpretation of morbidity burden in daily life. Methods: The study included a total of 1,032 adult individuals participating in a FH molecular cascade-screening program. The involved individuals were index cases (IC n=363), with genetic diagnosis or FH and their first-degree relatives (FDR, n=669). All patients were evaluated at the first session of the molecular diagnosis process. HRQL measurements, mental (MCS) and physical (PCS) component scores, was carried out with the Medical Outcomes Study (MOS) 12-Item Short-Form Health Survey (SF-12) questionnaire. Results: IC were older (52±13.1 vs. 46±16.2 years, P<0.05) and presented lower PCS than FDR (44.7±9.3 vs. 49.2±8.4, P<0.05). No differences were seen on the MCS component. Overall, generalized linear models showed that smoking habit (11.9% prevalence, P=0.006), previous diagnosis of hyperlipidemia (78.6%, P=0.020) and depression (13.5% prevalence, P<0.000) were significant predictors of MCS. The presence of heart failure (6.5%, P=0.018), angina pectoris (12.9%, P=0.005), previous myocardial infarction (12.3%, P=0.012), hypertension (33.9%, P=0.018) and obesity (12.8%, P<0.000) were all predictors of PCS. The presence of arrhythmias (10.7% prevalence) predicted both MCS and PCS (P=0.042 and P=0.00, respectively). Male gender (42.4%, P<0.000) and education level (< 9 years of background, 28% P<0.000) were social-demographic aspects predictive of differences in MCS and PCS, respectively. Conclusions: Reductions in the individuals’ reported quality of life were explained by differences in social-demographic characteristics but mainly by inadequate health/disease status, such as risk factors and previous CVD. Active FH genetic cascade diagnosis by promoting early and adequate medical care and thus preventing early CVD, may improve substantially the subjective appraisal of HRQL.
