Gestational anaemia--lack of blood -- may be a marker for cardiovascular disease (CVD) and stroke later, a study has found.Simple blood tests during pregnancy may reveal cardiovascular disease and stroke, up to 25 years before the disease outbreak, said researchers from Soroka Medical Center and Ben Gurion University, in Israel.In women with anaemia, CVD was 1.5 times higher than in women without anaemia. The rate of hospitalization for CVD was 4.35 per cent for women with gestational anaemia, compared to 3.7 per cent for the control group, the Xinhua reported.The high risk of CVD was significant even after neutralising factors that might bias outcomes such as smoking, obesity, and hypertension disorders.Among the diseases diagnosed in the pregnant patients are heart attacks, angina, heart failure, stroke, renal failure and hypertension with damage to internal organs.
