While everyone is on alert, those of us living with heart disease seem to be at higher risk of developing COVID-19. Learn more about symptoms and how you can help yourself avoid the corona virus.

While at Mayo Clinic, I learned that until recently, most cardiac research over the past 3-4 decades has been done primarily with (white, middle-aged) male participants, or with women participating in “statistically insignificant numbers”. And it’s often not because big bad researchers are deliberately refusing to include women in their studies. Although women do volunteer for hormone or breast cancer clinical trials – what we call the ‘bikini approach’ to women’s health research – we do not seem as interested in participating in cardiac research.
Many of us still mistakenly believe that heart disease is a man’s problem.
At a Canadian Cardiovascular Congress in Toronto, researchers announced that women are still under-represented in heart research. Although 53% of heart disease patients are women, we make up only 25-30% of the subjects in most cardiac studies.
Later, when I attended my first Canadian Cardiovascular Congress conference in person (with a press pass so I could interview researchers studying women’s heart health), I was shocked to learn that, out of over 700 scientific papers presented at this conference, only four of them focused specifically on women’s heart disease.
That doesn’t mean that treatments aren’t approved for female heart patients. But researchers know far less about how heart disease develops in women, how diagnostic tests that were researched and developed in (white, middle-aged) men work or don’t work in women, and how women may react to drugs and other treatments. So when reading research reports, always consider the gender balance in the study methodology.

♥ And here’s how to make sense of medical research studies.
RECENT RESEARCH UPDATES:
♥ February 2021: Women with heart disease get better treatment with female doctors: “Study concludes that women with heart health issues get better treatment if they’re seen by a female cardiologist, suggesting that female doctors may understand female patients better than men do.” Journal of the American College of Cardiology, February 22, 2021.
♥ November 2020: “Shared decision-making, a dialogue between patients and their care team that includes full disclosure of all testing and treatment options, discussion of the risks and benefits of those options and, importantly, engagement of the patient to express their own goals, is particularly relevant in the management of hypertrophic cardiomyopathy.” New guidelines on treating this heart condition from the American College of Cardiology.
♥ Awareness that heart disease is the leading cause of death among women declined from 2009 to 2019, particularly among Hispanic and non-Hispanic Black women and in younger women: a shocking report from the American Heart Association’s 2019 National Survey on women’s declining awareness of heart disease.
♥ March 2020: Daily aspirin is no longer recommended to protect against cardiovascular events in those who have never had a cardiac event. Heart and Stroke Foundation
♥ The $100 million ISCHEMIA clinical trial reported at the 2019 American Hearat Association Scientific Sessions suggested that invasive interventions like stents or coronary bypass surgery are no better than cardiac medications and lifestyle improvements in patients with stable angina. Read about it from Shelley Wood in TCTMD
♥ “Patients who took their blood pressure pills at bedtime had a 45% reduction in overall cardiovascular events.” 19,000 patients living with high blood pressure were randomly assigned to take their medications either on waking or at bedtime, and followed for an average of six years.” European Heart Journal, October 22, 2019.
♥ Myocardial Infarction in Young Women: An Unrecognized and Unexplained Epidemic – authors of this study in the cardiology journal Circulation report “a staggering increase” in the annual incidence of hospitalized heart attack among young women (35–54 years old) but the incidence decreased among men in the same age bracket. February 19, 2019.
♥ Fewer Lights/Sirens When a Woman Heart Patient is in the Ambulance – When women and men with heart attack symptoms called 911, women were less likely to receive aspirin, be resuscitated, or be transported to the hospital in ambulances using flashing lights and loud sirens.
♥ Women With Heart Failure: Unheard, Untreated, and Unstudied – Although women with a type of heart failure called “heart failure with reduced ejection fraction” (HFrEF) live longer than men, their additional years of life are of poorer quality, with greater self-reported psychological and physical disability. “The explanation for this different sex-related experience of HFrEF is unknown as is whether physicians recognize it. Women continue to receive suboptimal treatment, compared with men, with no obvious explanation for this shortfall.”
♥ Women are more likely to die from heart attacks than men are, but not if they’re treated by female Emergency Department doctors – Proceedings of the National Academy of Sciences, August 2018.
♥ Taking high doses of Biotin (vitamin B7) can lead to false negative blood tests of troponin, a cardiac enzyme that’s used to diagnose heart attacks – some dietary supplements to support hair/skin/nail health are 650 times higher than the recommended daily maximum.
♥ Women are more likely than men to seek care for their cardiac symptoms during the week before hospitalization – but both women and their physicians are less likely to attribute these early symptoms to heart disease compared to men. Pioneer cardiologist Dr. Nanette Wenger weighs in on the VIRGO study. Cardiology, February 2018.
♥ Female heart patients are more likely to be unexpectedly re-admitted to hospital with heart failure compared to men (22.3% of men vs. 29.6% of women). “We don’t know a lot about readmissions,” said lead author Dr. C. S. Kwok. American Journal of Cardiology, January 2018. ♥ Q: Maybe it’s about time we DID know more about why heart patients are being unexpectedly re-admitted after hospital discharge?
♥ Fewer Women Would Die of Heart Attacks if Given Same Treatments as Men – After accounting for the expected number of deaths seen in the average population, the researchers studied 180,000 people over 10 years and found that women had an excess mortality of up to three times higher than men’s in the year after having a heart attack. Journal of the American Heart Association, 2018.
♥ Ten-Year Mortality in the WISE Study (Women’s Ischemia Syndrome Evaluation) – An important study to all women whose cardiac symptoms have been dismissed because no coronary blockages were seen. “1 in 3 of the heart-related deaths in this cohort occurred in women without obstructive coronary artery disease, a condition often considered benign and without guideline-recommended treatments.”
♥ Women and Heart Disease: New Data Reaffirms Lack of Awareness By Women and Physicians – While 74% of women reported having at least one risk factor for heart disease, just 16% were told by their doctor that they were at risk. Journal of the American College of Cardiology, June 22, 2017.
♥ Higher Cardiovascular Risk If You’re Taking Calcium Supplements – Dr. Erin Michos of Johns Hopkins University reported that calcium supplements might increase cardiovascular risk, but dietary calcium was associated with a protective effect. Journal of the American Heart Association, October 11, 2016.
♥ Sex Differences in Young Patients with Acute Myocardial Infarction – Researchers in the U.S. and Spain report that young women (under age 55) with AMI represent a distinct, higher-risk population that is different from young male counterparts. This includes lower quality of life, more co-morbidities, higher clinical risk scores, less likely to undergo revascularization procedures like stents during hospitalization, and more delays in seeking emergency medical help. European Heart Journal: Acute Cardiovascular Care. July 2016.
♥ Gender Differences in Coronary Heart Disease – U.K. cardiologist Dr. Ramzi Y Khamis’ comprehensive look at the areas in cardiovascular disease where women are still either under-diagnosed, under-treated even when appropriately diagnosed, or both – published in the journal HEART from the British Medical Journal (2016).
