Arm exercise testing to predict the outcome of coronary artery
Iâ € ™ would like to share a research study which may be an alternative to pharmacologic stress testing. This is a procedure where a drug is administered intravenously to simulate the exercise in individuals you can not perform the exercise test on a treadmill due to injury or physical limitation. The drug increases the heart rate by dilating arteries to increase coronary blood flow. This study provides information about a less costly and less invasive protocol.
San Luis, MO â € "A study published by the International Department of Medicine, University of Washington School of Medicine, St Louis Veterans Administration Medical Center, used the exercise capacity of arm strength as a predictor of survival and mortality rates in response to myocardial infarction (MI) and coronary artery. The results were published in the January 2009 issue of the American Heart Association.
Traditionally, tests of effort and work of the leg cycle ergometer is used as a predictor, but patients with lower limb disabilities such as amputation and orthopedic or neurological disorders can not participate in this type exercise test. Since the arm exercise testing appears to provide similar data, a group of veterans was isolated and referred to evidence of tension arm ergometer.
359 patients who were unable or unwilling to participate in treadmill testing completed the study in St Louis VA Medical Center between November 1997 and November 2002. Each Veteran fasted overnight and took just a ½ dose of insulin in the morning of the test, if they were on insulin. Beta blocking agents were withheld, but all other medications were taken as usual. The patients gave their voluntary and informed consent for testing.
A brief history was taken each patient and physical examination began, after a 12-lead ECG (ECG) was taken as a starting point and repeats once per minute during exercise. A manual blood pressure reading was recorded every three minutes from the non-exercising arm and continued every two minutes once the exercise was complete.
The tests were performed with the patient sitting next cycle of a mural, electronically braked ergometer. exercise protocol included an increase in the rate work from 50 to 200 meters kilopond (kpm) every two minutes with the total test time 5-12 minutes. The endpoint of the trial was determined by the depletion and / or symptoms induced.
As a control, pilot test was conducted on 5 young subjects, healthy sedentary (4 men and 1 woman) 28 Â ± 7 years. comparative values were determined after oxygen uptake and maximum heart rate.
The participants, 354 men and five women, were followed for 63 Â ± 24 months from the date of the exercise test until December 31, 2006. There were 98 deaths (27%) during the monitoring period, and 33 IM (9%). 41 people (11%) underwent coronary revascularization with 11 deaths (27%) of 41 patients.
The average age of study participants Was 63 Â ± 11 years. Rest the systolic and diastolic blood pressure was similar in both survivors and nonsurvivors, but resting heart rate was somewhat higher in patients who died.
arm exercise capacity proved to be a major predictor of survival rate for ischemic disease the heart in general, but was not a predictor of myocardial infarction or coronary revascularization. The maximum average arm exercise workload among survivors was 463 Â ± 173 kpm while non-survivors of proof in a general class of 340 Â ± 155 kpm.
â € œOur results provide evidence that arm ergometer stress tests can provide prognostic information and clinical roughly equivalent to that reported in the literature for treadmill or move the legs on a cycle ergometer, â € reported the research team. Further studies are warranted to determine the feasibility of using the arm exercise as an alternative to drug control in patients with lower limb disabilities.
