Dr. Kirk Garratt, clinical director of interventional cardiovascular research at Lenox Hill Hospital in New York City, commented on the study.
"We know very well that when you have cardiovascular disease any exposure to any meaningful stimulant would be expected to increase heart risk, by changing the vascular dynamic of the blood vessels that control the blood flow through the brain and heart," he said. "We also know that these drugs can facilitate or trigger irregular heart rhythms, which can be very problematic.
"Cocaine, for example, can have a negative impact on people both with and without heart disease," Garratt added. "And those with heart disease face an especially elevated risk. So these findings are not really surprising."
