More than 13,000 cardiovascular experts met in Washington over the past few days for the Annual American College of Cardiology Scientific Sessions, where more than 2,000 studies are being presented so doctors and researchers can learn about the latest research in diagnosing, treating and preventing heart disease. Here's a small sample of the studies presented:
Married people have healthier hearts
You might have heard it before; being married may be good for your health.
In a new study, researchers screened 3.5 million adults for cardiovascular problems and found that those who were married had less heart disease and healthier blood vessels throughout the body than people who were single, divorced or widowed.
Dr. Jeffrey Kuvin, spokesperson for the American College of Cardiology, says the findings may be linked in part to the effects of stress and the strength of a marriage. In a healthy marriage, there may be less conflict and less stress. FULL POST

It wasn't supposed to happen to her. Just 32 and pregnant, Holly Carson woke with a crushing headache.
"It was ... like if somebody had a baseball bat taken to (my) head," says Carson. Having some medical training, she immediately suspected she was having a stroke.
At 26, med student Lauren Barnes' migraine took a turn for the worse. Then, "I had a rush of pins and needles sensation and tingling throughout the entire right side of my body," she says.
Stroke isn't just for the elderly, as Carson and Barnes can attest. Scientists have known for some time that women have some risk factors for stroke that are unique to them and others that are more commonly seen in women than men.
To make women more aware, the American Heart Association released the first guidelines for the prevention of stroke in women on Thursday. FULL POST

Nearly 80,000 people die as a result of drinking alcohol each year in North and Latin America, according to a new study published Tuesday in the Journal Addiction.
Researchers looked at alcohol as the cause of death by examining death certificates, over a two-year period in 16 North and Latin American countries. Men accounted for 84% of alcohol-related deaths.
Maristela Monteiro, study author and a senior advisor on alcohol and substance abuse at the Pan American Health Organization, says people are drinking too much and "it's killing people before they should be dying."
"These deaths are all 100 percent preventable," she says. FULL POST

Women who used birth control pills for three years or more have twice the risk of developing glaucoma later in life, according to new research.
Glaucoma is a disease that damages the eye’s optic nerve and is a leading cause of blindness in the United States.
It’s been well documented that low-estrogen levels following menopause contribute to glaucoma in women. Scientists don’t know exactly why this happens. But years of using birth control pills, which can also lower estrogen levels, may add to the problem.
The study, conducted by researchers at University of California, San Francisco, Duke University School of Medicine and Third Affiliated Hospital of Nanchang University, Nanchang, China, did not differentiate between women who took low-estrogen or regular birth control pills. Investigators theorize that when women are not on the pill, their natural estrogen levels go up and down, which seems to prevent the eye from developing glaucoma. When women go on the pill, their estrogen levels are consistent, and in some cases consistently low, which could cause them to develop the condition.
This research project is the first to suggest an increased risk of glaucoma in women who have used oral contraceptives for three or more years. The researchers looked at data on more than 3,400 women aged 40 and older from across the United States, who answered questionnaires about their reproductive health and eye exams. FULL POST

When Janice hit menopause, she had terrible night sweats and hot flashes, but she was scared to undergo hormone replacement therapy.
Janice (who asked that her full name not be used for privacy reasons) had heard this treatment might be dangerous to her heart, and worried about risking her health.
It's a concern many American women have shared over the past decade since the benefits of hormone replacement therapy have been called into question. A large study called the Women's Health Initiative (WHI) was instrumental in casting doubt on these hormones.
Tuesday, scientists from the WHI released what they say is the definitive study on the safety of hormone replacement therapy (HRT). The bottom line: It's OK for most healthy women who have just entered menopause to take hormones for a short period of time, but the researchers do not recommend it for long-term use. The results are published in this week's Journal of the American Medical Association.

Being married may significantly improve the likelihood of surviving cancer, researchers say.
In a new study of more than 700,000 people with diagnoses of the most deadly cancers in the United States, patients who were married were more likely to detect their disease early, receive potentially curable treatments and live longer. The study was published in the Journal of Clinical Oncology.
The researchers observed a 20% reduction in deaths among the patients who were married compared to unmarried patients - a benefit bigger than several kinds of chemotherapy used for treating cancer.

Numerous medical studies have shown that fatty fish is healthy for the heart. Now researchers say it may also help prevent a debilitating type of arthritis.
Just one serving a week of a fatty fish such as salmon, or four servings a week of a leaner fish such as cod, may cut your risk of developing rheumatoid arthritis by half, according to a study in the Annals of the Rheumatic Diseases.
Researchers reviewed the diets of 32,000 Swedish women who filled out two food questionnaires, one in the late 1980s and another a decade later.

Hormone replacement therapy has been a controversial issue for a lot of women over the last decade. Many have rejected any type of hormone therapy since a large, federally funded study found hormone replacement therapy could increase a woman’s risks for heart disease and strokes.
Now, a new study out of Yale School of Medicine suggests anywhere from 18,000 to 91,000 women in their 50s who had hysterectomies may have died prematurely in the last decade because they did not take estrogen-only hormone replacement therapy.

In some parts of the world, cancer patients are treated with some of the newest targeted cancer drugs which can cost more than$100,000 per year, while in other regions, patients don't even know they have cancer because they're not being screened.
But where pap smears are not available, there may be a decidedly low-tech way to screen for cervical cancer and reduce cancer deaths, according to a large clinical trial released Sunday at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago: swabbing a woman's cervix with vinegar.
This study out of India is one of the top five out of more than 5,300 studies presented at the conference. It was given a spotlight usually reserved for the newest blockbuster drug research. FULL POST
