“An observational study published inCirculationearlier this year suggested an increased risk of myocardial infarction and heart failure in women starting at systolic blood pressures of greater than 110 mmHg,” While hormonal changes throughout a woman’s life, especially during pregnancy and menopause,...
The evolution of high-pressure blood circulation in vertebrates has brought with it the risk of bleeding after injury to tissues. Mechanisms to prevent bleeding (i.e., hemostatic mechanisms) are essential to maintain the closed blood-circulatory system. Normal hemostasis is the responsibility of a ...
