Description
Hooman Kamel and co-authors separate what pregnancy itself does to the heart from what age adds. Cardiovascular complications drive much maternal death, yet age thresholds dominated past work. Their 2026 study compares each patient's event risk in pregnancy and after delivery against her own baseline. Pregnancy multiplies the risk of major cardiovascular events about sevenfold. Strikingly, that multiplier does not grow with age. The relative danger is the same at twenty-five and at forty.
Absolute excess risk tells the other half: flat at about three extra events per thousand pregnancies until age thirty-one, then climbing to ten per thousand by forty-four. Aging does not sharpen pregnancy's mechanism. Pregnancy amplifies whatever baseline risk a woman carries, and age fattens the baseline. Screening logic follows from that split.
