Objectives: Hypertension is one of the strongest modifiable risk factor for cardiovascular and kidney disease and the leading risk factor for mortality. Rapid controlled reduction of blood pressure (BP) may be necessary to prevent or minimize end-organ damage, despite the increased costs. Aim: To compare the cost-effectiveness of the treatment for the hypertensive crisis. Patients and Methods: 722 patients (pts) with high BP systolic blood pressure (SBP) >180 and diastolic blood pressure (DBP >90 mmHg, without signs of end-organ damage, contraindications for four drugs, who were admitted in the emergency department were enrolled in a prospective, single-blind study. The pts were selected to be treated with 20 mg nifedipine sublingual (s/l) (n=314pts), 20 mg furosemid iv (n=102 pts), nitroglycerin iv 5mg/5ml starting with 5 mcg/min initially, increased by 5 mcg/min every 3 to 5 minutes (n=63 pts), 20 mg enalapril s/l (n=243 pts). Electrocardiographic (ECG) recordings and biochemical balance were obtained during and Echocardiographic after the treatment. Checkup of BP was made after 5', 10', 15', 30', 1h, 2h, 4h, and 6h after the treatment, time which was awarded as sufficient for lowering BP ≤140/90 mmHg. Side effects were assessed and the costs were calculated for each patient until normalization of BP. Results: There were significant differences between the groups regarding the age, SBP and DBP values prior to treatment. The age was respectively 57.79±10.98 vs 54.34±9.35 vs 51.68±9.62 vs 53.66±11.15y, p<0.001. SBP at the start was 185.65±11.01 vs 183.02±0.2 vs 191.48±9.33 vs 180.03 ±8.33 mmHg, p=0.001 and DBP respectively 98.10±6.97 vs 94.85±6.50 vs 97.97±8.05 vs 92.03±7.67 mmHg, p=0.001. All the antihypertensive drugs significantly reduced SBP and DBP, but more quickly it was done by nitroglycerin and furosemid, this difference was seen in the first 5 min of the treatment. The values of BP <140/90mmHg were achieved after 20 min by nitroglycerine iv (136.59±7.16), by furosemide iv (140.53 ±7.46, and after 30 min by nifedipine s/l (140.09±13.64 and enalapril (137.45±7.93), p<0,001. There was a significant difference (p=0.017) between the groups regarding the cost of the treatment, the highest cost was incurred by nitroglycerin and furosemide, no significant differences were made between nifedipine and enalapril (p=0.314). No side effects were observed during the use of the drugs. Conclusion: Nitroglycerin iv and furosemide iv act quickly to reduce SBP and DBP, despite the higher costs.
