Some supplements can interfere with lab tests to diagnose or monitor health conditions, which can lead to life-threatening misdiagnoses or unnecessary additional testing. Biotin (vitamin B₇) can skew results from a blood test to diagnose heart attack. Other problematic supplements include vitamin C, which can interfere with blood sugar readings and stool tests; calcium, which can make bones appear denser than they are on bone density scans; and creatine, which can lead to falsely high readings of creatinine, a marker for kidney disease.

An estimated 2.5 million Americans have implanted heart devices, which can be affected by magnetic or electrical interference from electric vehicle charging stations, induction cooktop stoves, and smaller gadgets such as smartphones and wireless earbuds. Magnetic energy can cause pacemakers to revert to a preset mode that may be faster or slower than the programmed heart rate. Electrical interference can cause a pacemaker or implanted cardioverter defibrillator to mistakenly stop functioning or deliver an unneeded shock.

Many older people with orthostatic hypotension (a sharp drop in blood pressure upon standing) have no related symptoms such as dizziness or lightheadedness. But they may face an elevated risk of unexplained falls.

Certain drugs, supplements, or foods can interact with common heart medications. Known as drug-drug or drug-nutrient interactions, these can occur at any point of the drug’s "life cycle:" absorption, metabolism, or excretion. When a drug or other substance alters the absorption or metabolism of another drug, this may reduce or increase its effects. For example, grapefruit juice can elevate blood levels of certain statins and potentially increase the risk of side effects.

After a drug is approved by the FDA, unexpected safety problems may be discovered. Depending on the level of concern, different safety warnings may be issued –– including a black box warning designed to call attention to serious or life-threatening side effects.

In November 2022, the FDA called out seven supplement companies for illegally claiming their products could treat or prevent cardiovascular disease, such as atherosclerosis or heart failure.

Stroke survivors who take their blood pressure drugs as prescribed may be less likely to experience a serious fall compared with those who don't take their medications on schedule.
