3. CT Angiograms
A CT angiogram can reveal blockages in blood vessels and help diagnose heart disease. While useful in specific situations, it does come with risks: exposure to radiation and the use of contrast dye, which can be tough on aging kidneys.
The American Heart Association emphasizes that these scans should be reserved for patients with concerning symptoms or unclear diagnoses. In many cases, less risky tools like ultrasounds, stress tests, or simple lifestyle monitoring are better choices.
Dr. Sharonne Hayes, a cardiologist at Mayo Clinic, puts it plainly: “For an older patient without symptoms, jumping straight to a CT angiogram can cause more harm than good. Medications, diet changes, and exercise often provide better results.”
4. Annual Blood Panels
Many people are used to the idea of an annual “full blood work” as part of their checkup. While blood tests can be valuable, repeating broad panels every year without reason can lead to false positives, unnecessary anxiety, and costly follow-ups.
The Choosing Wisely campaign, created by the American Board of Internal Medicine, specifically advises against routine annual panels in healthy adults. Instead, tests should be targeted. For example, if you’re experiencing unusual fatigue, it makes sense to check your thyroid. If you’ve had bone problems, vitamin D and calcium levels may be appropriate.
Helen, 76, used to ask for “the works” every year. But after one test flagged a slightly abnormal kidney value, she spent weeks worrying and paying for follow-up appointments only to discover it was a harmless blip. Now, she and her doctor focus only on specific tests guided by her symptoms and medical history.
