How women can have heart attacks without having any blocked arteries

by Carolyn Thomas  ♥  @HeartSisters

Turns out that the kind of heart attack that I had (caused by a 95% blockage in the big left anterior descending coronary artery) – the so-called widowmaker heart attackmay actually be relatively uncommon  in women. You might guess that fact by its nickname.  It’s not, after all, called the “widower-maker”.

While cardiologists warn that heart disease can’t be divided into male and female forms, there are some surprising differences. Cardiologist Dr. Amir Lerman at the world famous Mayo Clinic in Rochester, Minnesota, told the Los Angeles Times recently:

“When it comes to acute heart attacks and sudden death from cardiac arrest, women have these kinds of events much more often without any obstructions in their coronary arteries.”

Instead, it appears that a significant portion of women suffer from another form of heart disease altogether. It affects not the superhighway coronary arteries but rather the smaller arteries, called microvessels. These tiny arteries deliver blood directly to the heart muscle.

Ironically, I can now boast two diagnoses for the price of one – first, the widowmaker heart attack caused by a fully occluded coronary artery back in 2008, and then, after several months of puzzling, ongoing cardiac symptoms – like chest pain, shortness of breath, and crushing fatigue – a second diagnosis of inoperable coronary microvascular disease.

Bypassing bypass surgery by growing new arteries

by Carolyn Thomas  @HeartSisters

The human body is endlessly fascinating, isn’t it? Consider how humans get started in the first place – only after one tiny sperm, one of hundreds of millions, has somehow negotiated its way past the lethal acid coating the vagina and made its long journey up to the waiting egg.  The odds are stupefyingly against that one brave little sperm. How did any of us even get born?

Also, consider the heart.

Before my heart attack, I had never heard of the heart’s little collateral arteries. These are small, normally closed arteries that, in times of dire need (like a blocked coronary artery that can lead to a heart attack) can “wake up” and enlarge enough to form a kind of detour around the blockage, thus providing an alternate route of blood supply to feed the oxygen-starved heart muscle. Do-it-yourself bypass surgery! Continue reading “Bypassing bypass surgery by growing new arteries”
