Comparison of exercise, dobutamine-atropine and dipyridamole-atropine stress echocardiography in detecting coronary artery disease

Table 1 Peak hemodynamic data during dobutamine, dobutamine-atropine, dipyridamole, dipyridamole-atropine and exercise stress tests.

	Dob	Dobatro	Dip	Dipatro	Ex
Heart rate, beat/min	110 ± 27	138 ± 25*	91 ± 15	125 ± 25*	148 ± 22**
Systolic blood pressure, mmHg	155 ± 20	160 ± 30*	138 ± 22	158 ± 20*	182 ± 24**
Diastolic blood pressure, mmHg	98 ± 15	103 ± 10	90 ± 9	97 ± 12	109 ± 14**
PRR, mmHg × beat/min/100	170 ± 64	221 ± 60*	126 ± 32	198 ± 59*	348 ± 61**

Values are given as mean ± SD. Dob indicates dobutamine; Dobatro, dobutamine-atropine; Dip, dipyridamole; and Dipatro, dipyridamole-atropine; RPP, rate-pressure product. Asterisk indicates significant difference for Dobatro vs. Dob, and Dipatro vs. Dip (p < 0.0001). Two asterisks indicate significant difference between Ex and other tests (p < 0.0001 for all).
