OBJECTIVES Higher CSBP than brachial SBP in individual patient increases cardiovascular (CV) risk. For follow-up it is important to assess the reproducibility of such measurements. The aim this study was these differences, expressed as a CSBP/BrachSBP ratios. SUBJECTS AND METHODS Eighty-three patients on antihypertensive therapy were analysed for ratios after time interval several month up year...

BACKGROUND The current systolic blood-pressure threshold for hypertension treatment is 140 mm Hg for all adults. WHO and the International Society of Hypertension have proposed that normal pressure be lower than 130 mm Hg, with an optimum pressure of less than 120 mm Hg. These recommendations are based largely on the assumption that cardiovascular and overall mortality depend in a strictly incr...

Peripheral systolic blood pressure is amplified above central aortic systolic pressure, but the late systolic shoulder of the peripheral pulse may approximate central systolic pressure. Because late systolic pressure also determines the peripheral augmentation index, a measure of pressure wave reflection within the systemic circulation, this implies a direct relationship between amplification a...

Right atrial pacing was performed in 41 subjects with coronary heart disease. Twenty developed angina pectoris during pacing, while 21 did not. The extent of coronary artery disease, as judged by selective cinearteriography, was similar in the two groups. Both had significant increases in heart rate and pressure-time per minute, but there was no significant difference in either of these paramet...

Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...

tive prosthetic orifice size may have to be performed at least a few weeks after valve insertion. Second, in some patients, the problem is compounded by the small size of the annulus compared with the size of the patient. My article was not written just to highlight the difficulties of a small aortic annulus. Dr. Kinsley's ability to insert a prosthetic valve size commensurate with the patient'...

OBJECTIVE Systolic pressure variation results from cyclical fluctuation in the intra-thoracic pressure associated with mechanical ventilation and has been used as a measure of relative hypovolemia in mechanically ventilated patients. The impact of the magnitude of the tidal volume and airway pressure on systolic pressure variation, however, has not been examined in mechanically ventilated patie...
