Abstract
Hypertension and diabetes may increase the risk of adverse events in the general population and patients with cardiomyopathies, however, their role in patients with cardiac amyloidosis (CA) is still unclarified. to evaluate the effect on phenotype and clinical outcomes of hypertension and diabetes in patients with CA. Data from 5 Italian Amyloidosis Referral Centres were used to describe clinical characteristics and outcomes of patients with CA based on the presence of a history of hypertension and diabetes. The study includes 887 patients with CA (311 light chain CA, 87 hereditary transthyretin CA, 489 wild-type transthyretin CA). Median age was 75 years (67-81), and 692 (78 %) were men. Five hundred-seven (57 %) patients had hypertension, 127 (14 %) had diabetes. In multivariable linear regression analysis, hypertension was associated with an increased interventricular septal thickness (coefficient 0.63,95 % CI 0.2-1.06), and augmented E/e' ratio (1.92,95 % CI 0.55-3.29). On Cox regression, diabetes was independently associated with death and heart failure hospitalizations (HR 1.45,95 % CI 1.05-1.99, p = 0.02). Patients with hypertension present a more severe phenotype with increased LV wall thickness and more severe diastolic dysfunction compared to non-hypertensive. The presence of diabetes in this cohort is associated with an increased risk of adverse outcomes.
