Hemodynamics of elevated blood pressure.
In young hypertensives (less than 30 years) there are signs of increased sympathetic drive with higher than normal heart rates and cardiac output. Over the years, established hypertension is associated with an elevated total peripheral resistance, an abnormally low cardiac output (particularly during exercise), and reduced coronary reserve.
