Abstract

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 1950="1950" 2008="2008" age="age" all="all" and="and" born="born" cardiovascular="cardiovascular" cohort="cohort" death="death" denmark="denmark" disease="disease" early="early" effect="effect" estimated="estimated" family="family" followed="followed" for="for" from="from" in="in" incidence="incidence" individuals="individuals" of="of" on="on" poisson="poisson" premature="premature" rate="rate" ratios="ratios" reflecting="reflecting" regression="regression" risk.="risk." s="s" the="the" this="this" to="to" using="using" we="we" years="years">

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.
