Air pollution, sex, coffee, alcohol, rich food, intense workouts and angry outbursts are all triggers for heart attacks, according to a widespread analysis of prior research.

Smog factored in significantly to upping the risk of cardiac arrest, RIFT Platinum with 7.4 percent of heart attacks linked to highway pollution, according to the European study.

Other routine activities also had a hand in heart trouble, including drinking coffee (blamed for 5 percent of attacks), having sex (2.2 percent), rift gold eating a heavy meal (2.7 percent), engaging in physical activity (6.2 percent), drinking alcohol (5 percent) and smoking pot (almost 1 percent).

Even emotions were pegged as culprits, according to the findings published Feb. 24 in The Lancet.

Negative emotions were associated with almost 4 percent of heart attacks, RIFT Platinum anger with more than 3 percent and positive emotions with 2.4 percent, the authors said.

"The reality is that we think many different things potentially feed into the pathway that can lead to having a heart attack," Dr. Bruce Rutkin, a cardiologist at North Shore University Hospital, told AOL Health. "Very rarely is there just one factor."

He said that the observational, retrospective study doesn't prove a hard-and-fast cause-and-effect relationship between the triggers and heart attacks, Rift Gold but said they can play a role. But it remains unclear exactly how they contributed or how much exposure to them was experienced by patients with heart disease.

"Some of these things are very difficult to quantify," Rutkin said.

The scientists admitted that each factor taken separately poses only a small risk. rift gold But when considered together and across different populations, they can be cumulative and significant.

"Small risks can be highly relevant if they are widely distributed in the population," said lead researcher Tim S. Nawrot, assistant professor of epidemiology at the Hasselt Centre for Environmental Sciences in Belgium, according to HealthDay News.

Smog, for instance, is a relatively minor cause of cardiac arrest, but because more people are exposed to it than to cocaine, a much higher risk factor, it was found to trigger more heart attacks than the drug did.

The researchers reviewed 36 prior studies on environmental causes of heart attacks. Their meta-analysis compared various factors to establish commonalities, but wasn't able to draw definitive conclusions about cause and effect.

Air pollution, RIFT Platinum for example, raised the risk of having a heart attack by almost 5 percent. Coffee increased the chances 1.5 times, alcohol 3 times and cocaine 23 times, the authors found.

"It's not really surprising, but it is disturbing," Lenox Hill Hospital pulmonologist Dr. Len Horovitz told AOL Health. Rift Gold "There's more out there than we know."

Typical risks associated with heart disease are smoking, obesity, high blood pressure, diabetes and family history, Rutkin said.

But the factors highlighted in the new study may all be associated with elevating blood pressure and inflammation in the arteries, both of which can trigger a heart attack, he explained. The rupture of plaque in the arteries and heightened blood platelet activity may also occur as a result of exposure to the substances and activities mentioned. Those conditions can contribute to heart problems, according to Rutkin.

"None of this changes our traditional feelings of how we counsel patients," he told AOL Health. "Use common sense. It's a matter of modifying the things we can."

Horovitz preaches moderation too. He suggests installing indoor air filters, rift gold which help reduce pollution's fine particles that can lodge themselves deep inside the lungs and cause cardiovascular trouble. He also has some other advice.

"Don't smoke. Lead a good lifestyle," he said. "A cup of coffee a day is fine, five cups is not. A drink a day is a good thing, five drinks is not. And don't run behind a bus."
