Insights
Symptomatic patients with high blood pressure (hypertension) responded similarly to symptomatic or anti-hypertensive drugs. Both treatments effectively reduced blood pressure and symptoms, allowing for similar discharge rates in the emergency unit setting.
Area of Science:
- Cardiology
- Emergency Medicine
- Pharmacology
Background:
- Hypertensive emergencies require prompt and effective treatment.
- Symptomatic medications and anti-hypertensive drugs are potential options for managing hypertensive crises.
- Patient compliance with treatment and lifestyle modifications significantly impacts blood pressure control.
Purpose of the Study:
- To compare the therapeutic efficacy of symptomatic medications versus anti-hypertensive drugs in hypertensive patients presenting with symptoms to the Emergency Unit.
- To evaluate the impact of these treatments on patient symptom resolution and blood pressure reduction.
Main Methods:
- A randomized, blind clinical trial was conducted with 100 hypertensive patients experiencing elevated systolic blood pressure (SBP) between 180-200 mmHg and/or diastolic blood pressure (DBP) between 110-120 mmHg.
- Patients were randomized to receive either symptomatic medication (dipyrone or diazepam) or an anti-hypertensive drug (captopril).
- Discharge criteria included resolution of symptoms and reduction of SBP to below 180 mmHg and DBP to below 110 mmHg within 90 minutes.
Main Results:
- The study population (mean age 54.4 years) consisted primarily of females with chronic hypertension, irregular medication use, and obesity.
- Headache, chest pain, and dyspnea were the most common presenting symptoms.
- No statistically significant difference was observed in the number of patients meeting discharge criteria between the symptomatic drug group and the anti-hypertensive drug group (p=0.165).
Conclusions:
- Symptomatic medications, while not statistically significant, led to a slightly higher rate of blood pressure reduction below discharge criteria compared to anti-hypertensive drugs.
- Both treatment approaches were effective in resolving symptoms and reducing blood pressure in hypertensive patients in the emergency setting.
- Patient characteristics such as prior hypertension diagnosis or treatment adherence did not influence discharge outcomes.
Objective:
Compare the therapeutic response of symptomatic, hypertensive patients to symptomatic medication or anti-hypertensive drugs at the Emergency Unit.
Methods:
A randomized, blind clinical trial involving 100 (one hundred) patients assisted at the Cardiology Emergency Unit at Oswaldo Cruz University Hospital (HUOC). All patients reported symptoms associated to systolic pressure (SBP) between 180 and 200 mmHg and/or diastolic pressure (DBP) between 110 and 120 mmHg. Patients were randomized for treatment with symptomatic (dipirone or diazepan) or anti-hipertensive drug (captopril). Those reporting any associated clinical condition and in need of immediate treatment at the Emergency Unit were excluded from the study. Patients reporting no symptoms, and systolic pressure reduced to levels under 180 mmHg and diastolic pressure under 110 mmHg after the 90-minute period were considered as having met discharge criteria.
Results:
Mean age of population studied was 54.4 years old, most commonly females. Patients were chronic hypertensive, on irregular pharmacological treatment, with low compliance to non-pharmacologic actions, and classified as overweight and obese grade I. Headache, type D (non-angina) chest pain, and dyspnea were the most frequent complaints. The number of patients treated with symptomatic drug who reached discharge criteria was similar to that of patients treated with anti-hypertensive (p=0.165). No association was found between previous high blood pressure (HBP) diagnosis (p=0.192), pharmacological treatment (p=0.687), and non-pharmacological treatment and discharge criteria.
Conclusion:
Blood pressure (BP) was reduced below levels for discharge criteria for a (non-significant) higher rate of patients treated with symptomatic drug, who were turned into asymptomatic after the observation period.
