Research Question:
A zinc deficiency increases the chance of getting a heart attack?
Study Design:
This overview article contained 41 case-control studies with 2886 participants.
Results and conclusions:
The researchers found that patients who had a heart attack have low zinc status (less zinc in the body) [SMD =-1,148, 95% CI =-2,365 to-1,331] had than healthy people.
The researchers found in the subgroup analysis that patients who have had a heart attack a low serum zinc status [SMD =-1,764, 95% CI =-2,417 to-1.112] had than healthy people.
The researchers found in the subgroup analysis that patients who have had a heart attack her a low zinc status [SMD =-3.326, 95% CI = 4.616-to-2.036] had than healthy people.
The researchers found that both men in the subgroup analysis [SMD =-3,350, 95% CI =-149 to-1,348] and women [SMD =-1,652, 95% CI =-3,440 to-1922] who have had a heart attack had a low zinc status than healthy people.
The researchers found in the subgroup analysis that the zinc status in Asian patients who have had a heart attack, lower than in European patients.
The researchers concluded that there is a significant relationship existed between zinc deficiency and getting a heart attack.
