Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

As children transform into adults some of the genes involved in controlling their blood pressure change as well

The study of black and white identical and fraternal twins showed that changes in gene expression between ages 14 and 18 accounted for up to one third of the blood pressure variation that occurred by age 18, says Dr. Harold Snieder, genetic epidemiologist at the Medical College of Georgia.

Poor physical fitness associated with lower socioeconomic status and higher rate of death

Individuals who have abnormal findings on exercise stress testing are more likely to have lower than higher socioeconomic status, and these physiologic characteristics may help account for the correlation between low SES and a higher rate of death

Study examines treatment to maintain blood pressure in those with disorder causing postural drops

Use of a medication called pyridostigmine alone or in combination with low-dose midodrine appears to improve standing blood pressure in patients with orthostatic hypotension, a fall in blood pressure associated with postural changes and standing

Acetazolamide improves central sleep apnea in heart failure

Since sleep apnea is associated with heart failure, patients who take a single dose of acetazolamide - a mild diuretic and respiratory stimulant - before going to bed exhibit less sleep apnea, improved blood oxygen levels and fewer daytime symptoms of sleepiness.

Fish oil supplements prevent declines in heart rate variability

A two-gram fish oil supplement given daily to elderly persons prevented a decline in heart rate variability caused by tiny, dangerous airborne pollutant particles. Heart rate variability, a measure of the autonomic nervous system's regulation of the heart, is an independent risk factor for cardiac arrhythmias, heart attack or sudden death.
