Purpose: To evaluate the prevalence and severity of uncontrolled hypertension (HTN) in patients referred to the cardiac catheterization laboratory for suspected coronary artery disease in an inner city teaching hospital. Methods: Intra-arterial blood pressure measurements obtained during cardiac catheterization using WITT Biomedical ™ system in the 3425 consecutive patients (mean age = 60, females = 52%, African american = 67%, hispanic = 19%, caucasian = 11%) over a 3 year period were analysed. Uncontrolled HTN was defined as BP > 140/90 mmHg. Patients were divided into 2 groups: Group I (Patients with known history of hypertension, n=2541, 74%) and Group II (Patients without known history of hypertension, N=884, 26%). Results: Of the 3425 patients evaluated, 1533 (44.8%) had a blood pressure greater than 140/90 mmHg and 847 patients (24.7%) had a blood pressure greater than 160/100mmHg (See Table). Intra-arterial blood pressure recordings of patients referred for cardiac catheterization Blood Pressure All patients Group I (known history of HTN) Group II (No known history of HTN) Males Females In mmHg No. (%) No.(%) No.(%) No.(%) No.(%) 200/120 155 (4.5%) 131 (5.2%) 24 (2.7%) 31 (1.9%) 123 (6.9%) Total 3425 2541 884 1641 1784 Conclusion: In a predominantly African American group of patients with suspected coronary artery disease that underwent cardiac catheterization, Almost half of all patients had uncontrolled HTN (n=1533/3425, 44.7%). Of the patients with known and “presumably” treated hypertension, 51% had BP >140/90 (Group I). Almost 5% of all patients presenting to the cardiac cath lab had a BP >200/120 mmHg The blood pressure control in female patients tended to be worse than the male patients
