Hypertension risk factors who underwent dobutamine stress echocardiography

Rabindra Nath Das

Objectives and methods: The present report aims to identify the hypertension risk factors who underwent Dobutamine stress echocardiography (DSE) (558 heart patients), based on the routine secondary data set (UCLA Statistics Web Site) without any specific setting. Joint generalized linear statistical gamma models are used. Results: The present identified statistical significant hypertension risk factors from three blood pressure (basal, systolic, and maximum) analyses are the following: basal heart rate (bhr) (P<0.0001), double product (DP) of basal blood pressure and heart rate (basedp) (P<0.0001), peak heart rate (pkhr) (P<0.0001), DP of peak heart rate & systolic blood pressure (dp) (P<0.0001), dobutamine dose (dose) (P=0.0268), maximum heart rate (maxhr) (P<0.0001), percent maximum predicted heart rate (pctM-phr) (P=0.0312), DP on maximum dobutamine dose and blood pressure (dpmaxdo) (P<0.0001), age (P=0.0048), chest pain (P=0.0505), resting wall motion abnormality on echocardiogram (restwma) (P<0.0001), positive stress echocardiogram (posSE) (P=0.0002), new myocardial infraction (newMI) (P<0.0001), recent angioplasty (newPTCA) (P=0.0252), recent bypass surgery (newCABG) (P=0.0482), history of hypertension (hxofHT) (P=0.0541), history of coronary artery bypass surgery (hxofCABG) (P=0.0529), any event (P=0.0289), and base line electrocardiogram diagnosis (ecg) (P=0.0312). Conclusions: Impacts of heart conditions, biochemical parameters, dobutamine dose and many others on hypertension have been identified based on probabilistic modeling. Most of the present findings and their effects are almost new in the hypertension literature.
