    Abstract:
    Central hemodynamics of coronary patients living in the arid zone (215 males aged 40-72 and 150 females aged 40-75) was assessed in comfortable weather conditions, 1-2 days before the invasion of the dust storm, upon its invasion and in hot weather season (+26-30 degrees C). Angina of effort functional class I, II and III was in 102, 198 and 65 patients, respectively. Atmospheric conditions before the invasion of the dust storm form a hypoxic type of weather while on the day of the storm the weather appears spastic resulting in arterial hypertension, elevated total peripheral resistance and heart beat in diminution of cardiac output and stroke volume. Hot weather brings about a hypotensive response, total peripheral resistance falls, cardiac output increases at the expense of enhanced heart beat as stroke volume decreases. It is concluded that under the climatic conditions of an arid zone coronary patients develop a complex of hemodynamic responses which function with strain to supply blood to organs and tissues.
