Just 5 drinks a week can hurt your heart

Pretoria News - - LIFESTYLE -

EVEN mod­er­ate drink­ing dam­ages the heart, a study re­veals.

As few as five glasses of wine a week can pro­duce greater signs of scar­ring and ab­nor­mal heart rhythms that raise the risk of strokes, ex­perts sug­gest.

So-called atrial fib­ril­la­tion – rapid and ir­reg­u­lar heart­beats – is al­ready known to be caused by ex­ces­sive drink­ing.

But re­searchers also found a wor­ry­ing im­pact from mod­er­ate drink­ing, which can be as low as a weekly in­take of five 175ml glasses of wine or five pints of beer at 4% strength.

Atrial fib­ril­la­tion oc­curs when ab­nor­mal elec­tri­cal im­pulses over­ride the heart’s nat­u­ral pace­maker, which can no longer con­trol the rhythm. The con­di­tion puts pa­tients at in­creased risk of strokes be­cause blood may not be prop­erly pumped out of the heart, which may cause it to pool and clot.

For the study, re­searchers at the Al­fred Hos­pi­tal in Mel­bourne per­formed “de­tailed in­va­sive test­ing” on the hearts of 75 pa­tients who al­ready had atrial fib­ril­la­tion over two years. | Daily Mail
