چکیده

OBJECTIVES The purpose of this study was to examine the effect of a family history of premature death, cardiovascular death in particular, on the risk of early cardiovascular disease. BACKGROUND Studies suggest that fatal cardiovascular events and less severe cardiovascular diseases may co-occur in families. Consequently, a family history of premature death may indicate a familial cardiac frailty that predisposes to early cardiovascular disease. METHODS We ascertained family history of premature death (age <60 years) in all individuals born in Denmark from 1950 to 2008 and followed this cohort for early cardiovascular disease (age <50 years). Using Poisson regression, we estimated incidence rate ratios (IRRs) reflecting the effect of premature death in the family on early cardiovascular disease risk. RESULTS Among 3,985,301 persons followed up for 89,294,258 person-years, 129,825, 31,172, and 5,214 were diagnosed with any early cardiovascular disease, ischemic heart disease, and ventricular arrhythmia, respectively. IRRs for these conditions given a history of premature cardiovascular death in first-degree relatives were 1.72 (95% confidence interval [CI]: 1.68 to 1.77), 2.21 (95% CI: 2.11 to 2.31), and 1.94 (95% CI: 1.70 to 2.20), respectively. With ≥2 cardiovascular deaths in a family, corresponding IRRs were 3.30 (95% CI: 2.77 to 3.94), 5.00 (95% CI: 3.87 to 6.45), and 6.18 (95% CI: 3.32 to 11.50). The IRR for any early cardiovascular disease given a family history of premature noncardiovascular death was significantly lower, 1.12 (95% CI: 1.10 to 1.14) (p(cardiac vs. noncardiac) < 0.0001). CONCLUSIONS Family history of premature cardiovascular death was consistently and significantly associated with a risk of early cardiovascular disease, suggesting an inherited cardiac vulnerability. These results should be kept in mind when assessing cardiovascular disease risk in persons with a family history of premature cardiovascular death.

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease, which is caused by a multitude of mutations in genes encoding proteins of the cardiac sarcomere (1). Apical hypertrophic cardiomyopathy (AHCM) is an uncommon type of HCM. The sudden cardiac death is less likely to occur in the patients inflicted with AHCM (2). Herein, we presented the case of a 29-year-old man ...
