In a finding that challenges the way American cardiologists treat tens of thousands for heart attacks each year, a new study concludes patients who undergo a balloon angioplasty to open a blocked artery days after a heart attack gain no advantage over drug treatment.
Opening arteries that are 100 percent blocked within the first 12 hours after a heart attack through angioplasty to quickly restore blood flow to the heart is considered the gold standard for cardiac care.
But many doctors believe that eliminating the blockage, even well beyond the initial treatment window, is still a good strategy to prevent another heart attack, heart failure or death.
Each year, about 1 million people in the United States have a heart attack, and about half of them die.
