ABSTRACT
Mayo Clinic researchers have discovered a daily reduction in the flexibility of blood vessels, which may help explain why heart attacks and strokes occur most frequently in the early morning hours. The human body maintains a balance of blood pressure and blood flow by expanding or contracting blood vessels, says Virend Somers, M.D., Ph.D., a Mayo Clinic cardiologist and leader of the study. The study examined the blood vessel expansion caused by the endothelium in 30 normal, healthy volunteers who were nonsmokers.

Present treatment aims to restore blood flow to the heart muscle in order to limit the extent of permanent damage. Extensive damage keeps the heart from doing its job of pumping blood to...

    1. Shock in myocardial infarction must be vigorously combatted by increasing cardiac output and coronary blood flow if these patients are to be salvaged. 2. Inotropic, vasoconstrictor vasopressors such as norepinephrine and metaraminol are effective but have the disadvantage of the need for...
