y heart attack was caused by blockages in three major arteriestwo on the top of my heart and one on the bottom. Three out of 12 chances to have a major heart attack. But, when it comes to blockages that cause fatal heart attacks, men have it easy. Easier, that is, than women. Unless we have three or more arteries or coronary veins that are blocked 90% to 100%, you might say we have only a 1-in-12 chance of dying from our first heart attack. High-risk women have a 1-in-2, or 50% chance of their first heart attack killing them. Meneven the stupid ones like me that ignored the symptoms for over a year and even refused to go to the hospital when I had a significant heart attack on Christmas Eve, 2000generally survive a first heart attack.
The classic symptoms everyone with an ounce of common sense recognizes as signs that you're having a heart attack had been prevalent for well over a yearstabbing pain in the lower jaw, gripping pain in the chest, and an almost ritualistic numbing sensation in my left armevery morning as I rushed through Union Station in Washington, DC to catch the Washington Times shuttle for the fifteen minute ride to my office. An ardent believer in the power of prayer to heal, I prayed healing over my body every time my body warned me it was past time to see a cardiologist, confident that the Master Physician would clear the blockages and heal my body. When I finally ran out of warnings and had my heart attack I had ignored some very serious symptoms for at least six months. Simple, routine tests performed at my local hospital or doctor's office would have confirmed what I already knew to be true. Very likely, immediate treatment would have prevented the triple bypass I had in July, 2001. Had I gone to the doctor early enough, an angioplasty would have prevented the heart attack that ultimately required a 3 1/2 hour triple bypass to repair.
Generally speaking, its not that easy for women. Doctors have known ever since the pathologists began mapping the anatomical and physiologically distinctions between the sexes that men and women are at different mortality riskseven with the same illnesses and diseases. It is generally much easier to detect coronary disease in men than in women since in men, it is usually the larger, easier-to-detect coronary arteries that get blocked. With women, more commonly, heart disease begins when plaque builds in the smallest heart arteries, ever so slowly reducing the oxygen flow to the larger arteries that seldom become clogged, making it much more difficult for physicians to correctly diagnose female heart disease. Standard chest X-rays, catscans and angiographies usually miss the problem, and pulmonary problems usually become the suspect of choice. What brings the woman to her family physician is not the warning signs that suggest heart disease, but signs that suggest she is simply overworked since fatigue, a lack of energy and shortness of breath are the most common symptoms. Or, she may experience flu-like symptoms, complete with nausea, clamminess and cold sweat. Or, she may simply feel apprehensive and discomforted with a loss of appetite. Less than one in three women who suffer a heart attack feel chest pain or pain in the upper back, shoulders, neck, jaw or left arm. Many times, heart symptoms for women are mistaken for neuroticism or depressionparticularly when an angiography shows nothing abnormal. Where approximately 63% of the women who die from sudden-death heart attacks have coronary microvascular syndrome [CMS], less than 20% of men do.
And, for those of us males who are too stupid to recognize the traditional danger signsjaw pain, chest pain, shoulders or neck pain, numbness in the left arm a simple electrocardiogram [EKG] or a stress echo test will usually confirm the diagnosis. That is not generally the case in women. Of the estimated 12 million women with some form of heart disease, a quarter of them go undiagnosed because cholesterol plaque does not build into major blockages, but instead spreads evenly throughout the small artery walls, and is almost completely undetectable. When womenand occasionally mengo to their doctors complaining of shortness of breath and fatigue, ischaemia is more often than not misdiagnosed. When doctors use standard angiographic tests to check for blockages, CMS is almost always missed. Standard blood work tests may reveal elevated levels of bad cholesterol and evidence of angina, but not the severeness of the underlying cardiovascular disease. It is the failure to recognize ischaemia that causes the greater proportion of sudden death cardiac events in women.
Unfortunately, most cardiac research is based on white, middle-aged men. Most cadavers used by medical schools are the preserved corpses of white, middle-aged meneven though the medical community over the last few decades have been forced to acknowledge that men and women experience heart disease differently. "More and more," Dr. Frank Smart, MDa cardiologist and Director of Advanced Heart Failure/Cardiac Transplantation at the Texas Heart Institutesaid, "we're finding that men and women experience heart disease very differently. Physicians need to take women's health complaints seriously and understand that not all of the guidelines apply to women whose heart symptoms may appear nonspecific. It's important for women to have a good working relationship with their doctor and be aware of their own risk factors for heart disease."
The study Smart referenced shed light on just how differently women experience heart attacks than men. The studywhich examined more than 500 womenfound that 95% had developed new and specifically different symptoms up to a month or so before their heart attacks. Topping the list of complaints? Fatigue, restlessness and sleep problems. More than 70% of those interviewed said they experienced no chest discomfort as men do, and had no chest, back, neck, or shoulder painand no numbness or pain in the arms. Most of the women dismissed their symptoms as signs of stress related to their lifestyle. Some of those who sought medical attention claimed their doctors either completely misdiagnosed their symptoms, or marginalized them. The symptoms the women in the study group described at the time of their heart attacks were indicative of ischaemia. Fifty-eight percent complained of shortness of breath; 55% were experiencing weakness; 43% complained of extreme fatigue; and 39% complained of having a cold sweat and/or dizziness. Less than half had any chest "discomfort"but none described the pressure, tightness or ache as pain. Those experiencing such discomfort said it occurred in the back and high chest, just below the clavicle.
Shockingly, 96% of the women in the study group had family histories of heart disease. Sixty-two percent had previously been diagnosed with "heart-related problems" such as high cholesterol or greatly elevated levels of triglycerides. Thirty-three percent of the women in the study group had diabetes.
A study done in 2003 in Alberta, Canada may have revealed the answer to the question of why women are more prone to stealth ischemic heart attacksand why women who get CMS usually live about 5 years longer than men who are affected by ischaemia. Paul Armstrong, the lead researcher of the University of Alberta study concluded that "[b]iologically, women are less likely than men to develop acute coronary syndrome [ACS] at younger ages due to the presumed protective effect of estrogen."
The protective effect of estrogen on heart disease has both a positive and negative impactwith the negative outweighing the positive. While estrogen appears to help prevent massive arterial blockage in a large percentage of women as they reach their mid- to late-thirties and early-fortiesup to the onset of menopauseit does something much worse at that time. It spreads the plaque evenly throughout the small arteries, coating it in layers that cause slowly cause ischaemia, clogging the oxygen-starved arteries until blood flow through the heart is constricted and a heart attack results. Tragically for women with small-vessel heart disease, as the natural estrogen levels diminish with age, women who were protected from developing massive artery wall blockages in their younger years will suddenly experience the same type of Acute Coronary Syndrome that affects men of the same age grouponly the women will experience more sudden death heart attacks than their male counterparts who are not affected by CMS
What can a woman do? If you experience ongoing shortness of breath (often without any chest pains or discomfort), and seem always to have flu-like symptoms with nausea, cold sweats and clamminess and you fatigue easily, or you experience general weakness and dizziness and you have unexplained feelings of anxiety, loss of appetite and unspecific discomfort, get to the emergency room. You may be suffering a silent heart attackparticularly if you [a] are overweight, [b] smoke, [c] are diabetic, [d] have high cholesterol, [e] have a family history of heart disease, [f] are postmenopausal, [g] under stress, [h] don't see your doctor regularly and don't care for your own medical needs the way you take care of your husband or other family members. If you smoke, quit now. Women who smoke are up to six times more likely to suffer a heart attack or stroke than nonsmoking women. If you don't see your doctor regularly, start today. Know your numbers. Ask your doctor to check your blood pressure, cholesterol (HDL and LDL), triglycerides and blood glucose. Get to know your health numbers and the range they need to be in to keep you healthy.
