Abstract
To elucidate the demographic and clinical characteristics of a consecutive series of patients who presented for evaluation of orthostatic hypotension. From January 1, 1997, through September 30, 2001, we assessed retrospectively the demographic and clinical characteristics, antihypertensive medication use, and blood pressure variability in 100 consecutive patients with orthostatic hypotension who underwent 24-hour ambulatory blood pressure monitoring (OH group) and in a convenience sample of 100 age-matched patients who underwent 24-hour ambulatory blood pressure monitoring for evaluation of hypertension (HTN group). The OH group had a mean +/- SD age of 71.6 +/- 9.4 years, and 42% were women. The most common symptoms were light-headedness and weakness. Comorbid conditions included neurologic diseases (38%), preexisting hypertension (36%), hyperlipidemia (31%), cardiac arrhythmias and coronary artery disease (45%), and neoplasm (28%). During ambulatory blood pressure monitoring, postprandial decreases in blood pressure were noted in 83% of the OH group, supine or sleep hypertension in 84%, and noncompensatory heart rate variability in 75%. Findings on autonomic testing were abnormal in 99% of patients, serum creatinine value wa...Continue Reading
