Nearly half of U.S. adults have high blood pressure; however, only one-third of those who have the problem are aware of it. This is mostly because people only have blood pressure checked at doctor visits, so they don't know when it increases and requires medical attention. A simple solution is to take regular measurements with a home blood pressure monitor and keep track of their numbers to note changes.

Prices for six common heart tests and procedures at top-ranked U.S. hospitals showed surprisingly wide variations, according to a 2022 Harvard study. There was a 10-fold difference in the median prices patients pay for a heart ultrasound, and even larger disparities for procedures such as implanting a pacemaker. The differences may reflect power dynamics between hospitals and insurance companies. For both entities, factors such as location, size, and popularity influence that dynamic — which, in turn, affects the market dynamics that dictate costs.

Catheter ablation destroys spots in the heart responsible for atrial fibrillation. Although traditionally used as a second-line treatment after medications fail, undergoing ablation earlier in the course of the disease may be a good option. The overall success rate for catheter ablation is around 75%. People sometimes undergo a second procedure if the first one isn't effective; this boosts the success rate to nearly 90%. Many factors, such as age, other health problems, and duration of afib can affect a person's outcome after catheter ablation.

For many people, non-HDL cholesterol (which is total cholesterol minus HDL cholesterol) may be as good as (or even more reliable than) LDL for assessing a person's risk of heart problems.

A blood test for total testosterone is the usual first step in men concerned about low T levels. The best time to get tested is between 7 a.m. and 10 a.m.

A bubble study is a test done in conjunction with an echocardiogram to check for the presence of a tiny opening between the heart's upper chambers called a patent foramen ovale. Such an opening could explain how an unexpected stroke happened.

A 2022 study found that women who begin colorectal cancer screening at age 45 with colonoscopy or sigmoidoscopy are far less likely to develop the disease than women who don't undergo any screening or who start screening at age 50.

Benign prostatic hyperplasia, also known as an enlarged prostate, occurs in about 50% of men by age 60. It can lead to urination problems like a hesitant, interrupted, or weak urine stream; dribbling after urinating; a feeling that the bladder does not completely empty; and more frequent urination, especially at night. Medication and lifestyle changes are the first-line treatments, but if these don't work, men can choose from several types of surgery or less-invasive procedures to help manage symptoms.

Whether or not to continue PSA testing after age 70 depends on many factors, but especially a man's family history of prostate cancer and how comfortable he is about getting a biopsy or treatment if the test results suggest possible cancer.

Heart failure symptoms, such as being tired or out of breath, gaining weight, or having swollen ankles, can be overlooked and attributed to other causes. As a result, heart failure is not usually diagnosed until months or years later, when a person is hospitalized for it. By that point, the risk for dying from heart failure has already risen significantly, sometimes higher than the risk of death from cancer. Someone who has potential heart failure symptoms should talk to a doctor, especially if symptoms are new and if the person has diabetes, heart disease, high blood pressure, obesity, or an unhealthy lifestyle.
