The Risks of Undetected SMIs

Did you know 45% of heart attacks are a “silent myocardial infarction (SMI)” and are likely to go undetected? Expert says they are more common in men than women, and a person typically does not experience the intensity felt during a normal heart attack. Often it is mistaken for heartburn, indigestion and other age-related aches and pains.

A study published a few years ago in the Journal of the American Medical Association, found evidence of men suffering from undetected mild heart attacks. The study involved almost 2,000 people ages 45 to 84 (half of whom were men) who were free of any signs of cardiovascular disease. When doctors examined the group after ten years, “8% had myocardial scars, which are evidence of a heart attack. Most surprising was that 80% of these people were unaware of their condition.” The presence of myocardial scars was five times higher in men than in women.

While symptoms can be mild and brief, experts say to seek immediate medical help if you experience any of the following:

Discomfort in the center of the chest that lasts several minutes, or goes away and comes back. It can feel like an uncomfortable pressure, squeezing, or pain.
Discomfort in other upper-body areas, such as one or both arms, the back, the neck, the jaw, or the stomach.
Shortness of breath before or during chest discomfort.
Breaking out in a cold sweat, or feeling nauseated or lightheaded.

There are two methods used to detect a SMI and one or both may be done during a visit to the emergency room. The first is an electrocardiogram (EKG) or echocardiogram that spots heart muscle damage. The other is a blood test that looks for the molecular footprints of troponin T, a protein released by injured heart cells.

How Many Steps Per Day for Better Health?

We have all heard about the value of walking 10,000 steps a day but recent studies show it may not actually be the magic number. One study published by JAMA found walking 7,000 steps or more a day may decrease the risk for mortality and offer better overall health. In the cohort study of 2110 adults with a mean follow-up of 10.8 years, participants who walked at least 7000 steps a day, compared with those taking fewer than 7000 steps, had a 50% to 70% lower risk of mortality. Researchers also noted, “There was no association of step intensity with mortality regardless of adjustment for step volume.” A 2020 study found a decreased risk for mortality in participants who took 8,000 steps a day than those who only took 4,000 steps a day. In the same year, another study found more steps taken each day were linked to lower rates of diabetes. Researchers say the bottom line is evidence points to the importance of increased physical activity. Before you begin walking, talk to your health...

Be an Active Partner in Your Medical Care

Experts suggest that a good way to reduce medical errors regarding your care or that of a loved one is to be an active partner in the process whether in a hospital setting, doctors’ office or the pharmacy. In fact, a study showed 7% of hospitalized patients experienced an event that was considered preventable which negatively affected their health. Furthermore, harmful errors in primary and outpatient health care settings are typically related to diagnoses, prescriptions and use of medicines. Mistakes associated with misdiagnosis result in delayed treatment for the real problem and having the wrong medications prescribed or supplied can cause serious complications. However, it is important to keep in mind that some medical errors are a result of patients failing to disclose all the medications they take including prescription and over-the-counter drugs. Another problem is the failure to reveal pertinent details regarding a person’s prior medical history as well as lifestyle habits s...
