Varicose veins may be an early warning sign of potentially deadly blood clots suggests a study published Tuesday

Varicose veins warning sign of deadly blood clots

The authors say their findings support a number of previous studies, including German research that found a 7-fold higher rate of DVT among people with varicose veins than those without the condition.

They also found a higher incidence of pulmonary embolisms (PE) and peripheral artery disease (PAT) in people with varicose veins but the associations were less clear due to potential confounding factors.

They likewise had twofold the danger of fringe blood vessel disease, which lessens blood stream to the arms and legs.

More research is needed to understand whether that association is causal or if it reflects a common set of risk factors, the researchers said.

About 23% of adults are diagnosed with varicose veins in the US.

The condition is more likely to affect the elderly as age causes skin to lose elasticity and valves in veins to weaken.

They are easily recognised as bulging, knotty, purple or blue veins that are most commonly seen in the legs.

"Not much is known about varicose veins and the risk of other vascular diseases", Chang said.

In any case, they trust irritation in the veins are presumably included, whichever the reason.

Shyue-Luen Chang, MD, from the Vein Clinic, department of dermatology, Chang Gung Memorial Hospital and Chang Gung University College of Medicine in Taoyuan, Taiwan, and colleagues conducted a retrospective cohort study of participants aged at least 20 years without a history of DVT, PE or PAD in Taiwan's National Health Insurance program between 2001 and 2013.

They are also linked to pregnancy as gestation causes the volume of blood in the body to increase but reduces the flow from the legs to the pelvis.

In any case, the new examination, by researchers in Taiwan, proposes it ought to be viewed as a notice sign that somebody is in danger of more significant issues. The varicose veins group and the control group contained patients of similar mean age (54.5 and 54.3 years, respectively) and sex (69.3% women and 70.3% women, respectively).
