Summary
A hypertensive response during dobutamine stress echocardiography is rare, affecting only 1% of patients. This response was more common in individuals with a history of hypertension and higher baseline blood pressure.
Area of Science:
- Cardiology
- Clinical Echocardiography
- Hypertension Research
Background:
- Dobutamine stress echocardiography is a common diagnostic tool.
- Hypertensive responses during stress testing are not well-characterized.
- Understanding predictors of adverse responses is crucial for patient safety.
Purpose of the Study:
- To determine the incidence of hypertensive responses during dobutamine stress echocardiography.
- To identify patient characteristics associated with hypertensive responses.
Main Methods:
- Retrospective analysis of 3,129 dobutamine stress echocardiographic studies.
- Definition of hypertensive response: systolic blood pressure >= 220 mm Hg and/or diastolic blood pressure >= 110 mm Hg.
- Comparison of patient demographics and baseline cardiovascular parameters.
Main Results:
- A hypertensive response occurred in 30 patients (1%).
- Patients experiencing a hypertensive response were more likely to have a history of hypertension.
- Higher resting systolic and diastolic blood pressure levels were observed in patients with a hypertensive response.
Conclusions:
- Hypertensive responses to dobutamine stress echocardiography are infrequent.
- A history of hypertension and elevated baseline blood pressure are associated with a higher risk of hypertensive response.
- These findings may inform risk stratification and patient management during stress echocardiography.
