Women’s Heart Disease: Three Steps To Lower Risk

Heart attack symptoms for women

The most common heart attack symptom in women is the same as in men — some type of chest pain, pressure or discomfort that lasts more than a few minutes or comes and goes.

But chest pain is not always severe or even the most noticeable symptom, particularly in women. Women often describe heart attack pain as pressure or tightness. And it’s possible to have a heart attack without chest pain.

Women are more likely than men to have heart attack symptoms unrelated to chest pain, such as:

  • Neck, jaw, shoulder, upper back or upper belly (abdomen) discomfort
  • Shortness of breath
  • Pain in one or both arms
  • Nausea or vomiting
  • Sweating
  • Lightheadedness or dizziness
  • Unusual fatigue
  • Heartburn (indigestion)

These symptoms may be vague and not as noticeable as the crushing chest pain often associated with heart attacks. This might be because women tend to have blockages not only in their main arteries but also in the smaller ones that supply blood to the heart — a condition called small vessel heart disease or coronary microvascular disease.

Uterine Cancer: Risks, Diagnosis & Treatment

Uterine cancer is the most common cancer that affects a woman’s reproductive system, occurring mostly after menopause. It’s often diagnosed in an early stage. This video shares the symptoms and tests that may lead to a diagnosis.

Heart Disease: Molecular Mapping To Predict Risk

Vulnerability to heart disease can be projected before symptoms occur, Mayo Clinic discovered in preclinical research. This proof-of-concept study revealed that heart muscle changes indicate who is vulnerable to disease later in life. These changes can be detected from blood samples through comprehensive protein and metabolite profiling. This exploratory mapping, conducted in the Marriott Family Comprehensive Cardiac Regenerative Program within Mayo Clinic’s Center for Regenerative Medicine, is published in Scientific Reports.

“The team implemented state-of-the-art technologies to predict who is vulnerable and who is protected from heart disease,” says Andre Terzic, M.D., Ph.D., a Mayo Clinic cardiologist and the senior author. “In this era of post-genomic medicine, the acquired foundational knowledge provides guidance for development of curative solutions targeted to correct the disease-causing maladaptation.” Dr. Terzic is the Marriott Family Director, Comprehensive Cardiac Regenerative Medicine, for the Center for Regenerative Medicine and the Marriott Family Professor of Cardiovascular Research.

Dr. C’s Journal: Risks & Symptoms Of Heatstroke

We humans, in common with all mammals and birds, are homeothermic; we defend a body temperature of approximately 98.6 F.. When we are cold, we shiver to warm up. If we get too cold, such as being in 50° water temperature for 50 minutes, we have a 50% chance of dying. When we are warm, we sweat . When we get too warm, and our core body temperature rises above a critical point, approximately 105°, we may die.
This article is about HEAT EXHAUSTION, which is very topical, considering the season and the recent “heat dome” in the Pacific Northwest, not to mention global warming.

Our main defense against heat is to sweat. The water in sweat has a very high heat capacity. Changing sweat into water vapor requires a lot of heat, which is gratefully donated by the person who is too hot. Too much water vapor in the air, a high relative humidity, decreases the rate of evaporation, and therefore of Cooling. The critical measurement to warn us of Environmental overheating danger is the WET-BULB THERMOMETER,  which is used in tandem with the regular, dry bulb thermometer to calculate the relative humidity.

To give perspective, the wet bulb thermometer reached 77° And the dry bulb thermometer read 116° in the pacific northwest, associated with 118 fatalities. In 2003, when Europe was hit by a heat wave, the wet bulb thermometer reached 82.4°, associated with 30,000 deaths.
When it Feels hot (check the heat index), which is related to both the temperature and the relative humidity, you should start to worry. You should drink extra fluids, wear loose fitting clothes, stay out of the direct sun, avoid sunburn, exercise in the cool of the morning and night, not during the heat of the day, avoid closed vehicles, especially for children, and don’t get sunburned, which decreases the ability of the skin to produce sweat.

Certain groups have more risk, such as very young or old age, the obese, and  diabetics. Certain drugs, such as Alcohol, diuretics and beta blockers are factors.

Some typical symptoms are heavy sweating, faintness, dizziness, fatigue, muscle cramps, nausea, and headache. If you are hot, and think you might be experiencing heat exhaustion, you should stop all activity, move to a colder shaded place, and drink cool water or sports drinks.

If you’re caring for somebody, you should worry about confusion, agitation, and other central nervous system symptoms; the brain, together with the heart, kidneys and muscles are very susceptible to overheating.

Rectal temperature is the most reliable, and if it gets to 104°, immediate cooling is necessary, even packing in ice. Don’t bother to use aspirin, since it does not work with heat exhaustion. If coma or seizures develop, and the patient is diagnosed with a heat stroke, the fatality rate and long-term neurological complications are grave.

Please read the excellent article by Joe Craven McGinty in the July 10 Wall Street Journal, or the accompanying mayo clinic article. And stay Cool!

COVID-19: ‘REDUCING RISK NOW & PREPARING FOR THE NEXT PANDEMIC’ (PODCAST)

Virologist Angela Rasmussen talks about her battle against misinformation in the media, the virus, vaccines, disinfecting surfaces, home testing, and the next pandemic.

Eric J. Topol, MD: Hello, I’m Eric Topol for Medscape, and this is Medicine and the Machine. I’m so glad to have my colleague and partner in this podcast, Abraham Verghese, with me from Stanford. Today, we have the rarefied privilege to discuss the whole pandemic story, the virus and vaccines, with one of the country’s leading virologists, Dr Angela Rasmussen. Welcome, Angie.

Angela L. Rasmussen, MA, MPhil, PhD: Thank you so much for having me, Eric. It’s wonderful to be here.

COMMENTARY:

This podcast rectifies the blizzard of variously valid COVID information blaring on the media today, and adds to the discussion. Virologist Angela Rasmussen talks about several interesting aspects of the pandemic. BSL laboratories are discussed. BSL refers to Biological Safety Level. If a lab is dealing with a dangerous pathogen, like the hemorrhagic fever viruses, a level 4 lab is required.

“Moon suit”- like positive pressure encasements, special hoods and disposal devices are required to ensure containment of the organisms, and to prevent their escape into the environment.

She discussed the differences between live viruses, detected by PFUs (plaque-forming units) on a sheet of living cells, and what the available Covid tests pick up, namely RNA which may or not be infective. Saliva vs nasal swab samples, PCR vs antibody tests were compared. She explained what the “cycle number” in PCR tests refers to, and its significance She then discussed “fomite” transmission, and observed how hard it was to experimentally prove.

Aerosol transmission is thought more likely. Also discussed is how lucky we were that this Pandemic involved a Coronavirus, instead of another viral family that was less studied. Moderna, for instance, was in the process of developing a MERS ( a Coronavirus) Vaccine. She finished up with the observation that distancing and masks, although imperfect, are still useful.
