The most important sign is feeling really tired–even if after enough sleep. Other signs of heart disease in women are:
* Trouble breathing
* Trouble sleeping
* Feeling sick to the stomach
* Feeling scared or nervous
* New or worse headaches
* An ache in the chest
* Feeling “heavy” or “tight” in the chest
* A burning feeling in the chest
* Pain in the back, between the shoulders
* Pain or tightness in the chest that spreads to the jaw, neck, shoulders, ear, or the inside of the arms
* Pain in the belly, above the belly button

A promising treatment for a rare childhood disorder characterized by rapid aging and death prevented and even reversed the most devastating effect of the disease in mice. Researchers report in Proceedings of the National Academy of Sciences USA that the therapy could potentially help youngsters combat life-threatening cardiovascular disease resulting from the genetic condition Hutchinson-Gilford progeria syndrome.
Progeria affects one in every four million to eight million births; there are about 50 cases currently recognized worldwide with 10 to 12 in the U.S. Common symptoms include fragile bones, hair loss, limited growth, stiff joints and wrinkling of the skin by as young as age two; about 90 percent of progeria patients die by age 13 from fatal heart attacks or strokes, according to the Mayo Foundation for Medical Education and Research.
Researchers say that each progeria case arises randomly due to a single letter change in one gene of the child's DNA. The mutation—believed to occur in the father’s sperm before conception—results in the production of a toxic protein that attaches to and distorts the nucleus (the cell's command center containing its genetic material). Although cells normally multiply during growth and development, the misshapen nucleus cannot divide properly, ultimately damaging cells and accelerating the aging process.
Cardiovascular disease in these young patients develops as vulnerable cells lining the interior of major arteries (vessels that carry blood away from the heart) accumulate the toxic protein and die. This causes the arteries to stiffen and crack, leading to plaque buildup that blocks blood flow. Low-dose aspirin is often used to help prevent heart attacks, but some children even undergo bypass surgery or angioplasty (dilation of the arteries) to slow the disease.
Genetically engineered mice carrying the progeria mutation were used to test the effectiveness of farnesyltransferase inhibitors (FTIs) in combating progeria-related cardiovascular disease. FTIs restore the shape of the nucleus, thereby saving cells from premature destruction by preventing the toxic protein from attaching to the command hub.
Researchers found that FTIs not only prevented cardiovascular damage in young mice, but also reversed the disease in older animals treated after the onset of arterial damage. "We were amazed that [the drug] worked so well," says Francis Collins, a geneticist and former director of the National Human Genome Research Institute, who led the research team that identified the progeria gene mutation in 2003.A promising treatment for a rare childhood disorder characterized by rapid aging and... more

Recent research from both Australia and the United States has raised questions about energy drinks and says they may be harmful to some people.
The researchers say high-caffeine energy drinks may provide more than an energy boost as they may also boost heart rates and blood pressure levels and increase the danger of blood clots.
The results of a small study by researchers from Detroit's Henry Ford Hospital has found that the high levels of caffeine and taurine, an amino acid found in protein-rich foods like meat and fish, can affect heart function and blood pressure.
They advise people who have high blood pressure or heart disease to avoid energy drinks because they could have an impact on their blood pressure or change the effectiveness of their medications.
Dr. James Kalus who led the study, says increases were seen in both blood pressure and heart rate in 15 healthy volunteers with an average age of 26, who were resting and not exercising.
They say while the increases did not rise to dangerous levels in the group they could be significant in people with cardiovascular disease or those taking drugs to lower heart rate or blood pressure.
Energy drinks include Red Bull, Full Throttle, Amp and Rush.
For the study the group were asked not to consume other forms of caffeine for two days before and throughout the study in which they consumed two cans of energy drinks daily over seven days, each can containing 80 milligrams of caffeine and 1,000 milligrams of taurine.
The volunteers' heart rates rose by about 8 percent on the first day and 11 percent on the seventh day - systolic blood pressure rose by 8 percent on the first day and 10 percent on the seventh day, and diastolic blood pressure rose by 7 percent on the first day and 8 percent on the seventh day.
The researchers suggest the caffeine and taurine in the drinks were responsible for the changes.
Australian researchers say they have found that the sugar-free version of Red Bull may increase the danger of blood clots; they say it creates "sticky" blood, raising the risk of heart attack or stroke.
Researchers from the Royal Adelaide Hospital are warning that the drink "could be deadly" for people with heart abnormalities.
Lead researcher Dr. Scott Willoughby says though the incidence of sudden cardiac death is very low, the drink could be more deadly for people who have an unknown cardiovascular abnormality.
Red Bull which was first launched in Austria in 1987 is so-called after the ingredient taurine, the organic acid which was first isolated in a bull; it is prohibited as a soft drink in Norway, Uruguay, Denmark and Iceland.
The formula contains the same amount of caffeine as a cup of filter coffee, around 80mg and has benefited from much pop and sport celebrity endorsement.
The sugar-free version of the drink was launched in 2003.
Sales of Red Bull last year reached 3.5 billion cans, sold in 143 countries.
