Recent Questions & Answers

  • What is the obesity paradox?
  • The obesity paradox is a phenomenon in which obesity may have a protective effect on survival in certain groups of patients. For example, research has found that obese patients with heart failure or diabetes tend to live longer than similar patients who are underweight or a normal weight. Since obesity almost always has a negative impact on health, experts continue to conduct research to better understand this phenomenon.
  • What is grip strength?
  • Grip strength is a measure of how hard a person can squeeze an object in his or her hand. Grip strength is a useful indicator of overall muscle strength. Typically, grip strength increases during adolescence and declines with old age. However, a lack of physical activity and chronic health conditions can also impact muscle strength. Doctors may use grip strength to assess overall health of patients, especially as they age.
  • What is potassium?
  • Potassium is a mineral that helps the body’s nerves and muscles function. Potassium-rich foods include fruits, vegetables and beans like bananas, spinach, squash, potatoes and soy beans. Although potassium has been linked to reduced cardiovascular risk, too much potassium can be dangerous for certain individuals, like patients with heart failure or kidney disease.
  • What is a healthy weight for children?
  • Body mass index (BMI) is used to determine whether a child falls into an underweight, healthy weight, overweight or obese range. For children, BMI is calculated using height and weight, and takes into account both age and gender. Children with a BMI falling between the 5th and 85th percentile are considered a healthy weight.
  • What is coronary angiography?
  • Coronary angiography is a common medical test used to diagnose heart disease. During coronary angiography, a thin, flexible tube called a catheter is put into a blood vessel and threaded into the heart’s arteries. A dye is then released into the bloodstream, and X-ray pictures are taken to allow doctors see if the heart’s arteries are blocked or narrowed. For patients diagnosed with heart disease, coronary angiography can help guide treatment options such as lifestyle changes, medication and/or medical procedures.
