Groups2
Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Active Antihypertensive Treatment | Active antihypertensive treatment~Active antihypertensive treatment: Initial antihypertensive treatment with angiotensin-converting enzyme inhibitors (Enalapril) and/or calcium channel blockers as second line medication; and/or diuretics as third line medications. Based on patients' baseline BP level, the first-line medication (intravenous Enalapril) can be used alone, or in combination with second-line medication (calcium channel blocker), and third-line medication (diuretics) to achieve the target systolic BP lowering by 10% to 25% within the first 24 hours after randomization and to achieve systolic BP below 140 mm Hg and diastolic BP below 90 mm Hg and maintain this BP level afterwards during the hospitalization. | 28 | 1,988 | OG000 |
| Group 2 | Usual Care | Discontinue all home BP medications. | 43 | 1,987 | OG001 |
