Here's another reason to dread mornings: Heart attacks may be slightly larger early in the day. Scientists already knew that heart attacks were more common in the morning . But they were unsure about the size of those heart attacks. In rodents, the size of heart attacks roughly follows the body's natural circadian rhythms, so they suspected the same might be true of people. Spanish researchers analyzed records of 811 patients brought to the Hospital Clínico San Carlos in Madrid, Spain, between 2003 and 2009 for a STEMI -- ST segment elevation myocardial infarction -- a severe type heart attack.

Still nipping out of your workplace or a restaurant to cop a cigarette out on the sidewalk? You are public health hero, and a grateful nation salutes you. Workplaces and eating and drinking establishments that are free of second-hand smoke have shored up Americans' health even in the face of rising levels of obesity and Type 2 diabetes, says a new study. Published Monday in the Annals of Internal Medicine, the latest research focused on Olmsted County in Minnesota, and tracked the rate of heart attacks and sudden heart attack deaths in the wake of smoking bans that cleared Olmsted County's restaurants, bars and workplaces of tobacco smoke.

Taking calcium supplements increases the risk of having a heart attack, Swiss and German researchers reported Wednesday. The finding adds to the growing body of evidence that such supplements increase the risk to those who take them while providing only minimal benefits. The study is considered important because large numbers of people, especially elderly women, continue to take the supplements in hopes of minimizing loss of bone density. The body of evidence now seems to suggest that calcium consumed as part of a normal diet can, indeed, increase bone density and perhaps help lower blood pressure, but that supplements may be too risky for most people to take.

As if the lost income weren't enough, unemployment appears to increase the risk of heart attacks. According to a study published Monday in the journal Archives of Internal Medicine, people who were unemployed, had a history of unemployment, and even those who had short periods without work were all at a higher risk for heart attacks. Unemployment continues to be a major issue in the United States, with the national unemployment rate at 7.9%. And that leaves out many people who are underemployed or who have stopped looking for a job. Numerous studies have linked unemployment with health issues, most notably mental health.

Researchers have used cardiac stem cells to regenerate heart muscle in patients who have suffered heart attacks, also known as myocardial infarction. The small preliminary study, which was conducted by the Cedars-Sinai Heart Institute in Los Angeles, involved 25 patients who had suffered heart attacks in the previous one and a half to three months. Seventeen of the study subjects received infusions of stem cells cultured from a raisin-sized chunk of their own heart tissue, which had been removed via catheter.

The massive earthquake that struck Japan on March 11, 2011, and the tsunami that followed caused nearly 16,000 confirmed deaths, and more than 2,600 people are still missing and presumed dead, according to the National Police Agency. A new report in the New England Journal of Medicine adds to the casualty toll by confirming an increase in heart attacks in the weeks following the magnitude 9.0 quake. Researchers from Osaka University, Tokyo Women's Medical University and Kyoto University Health Service gathered data on heart attacks in Fukushima, Iwate and Miyagi, the three prefectures most affected by the quake and tsunami that struck off the coast of Sendai.
