The relation between N-terminal pro–B-type natriuretic peptide and heart failure☆ To the Editor, We read the article “Predictive cutoff point of admission Nterminal pro–B-type natriuretic peptide (NT-proBNP) testing in the emergency department (ED) for prognosis of patients with acute heart failure (HF)” by Golcuk et al with interest [1]. The authors aimed to determine a cutoff level of plasma NT-proBNP that could successfully predict the short- and long-term prognosis of patients with acute heart failure at the time of admission to the ED. They concluded that elevated NT-proBNP levels at the time of admission are a strong and independent predictor of allcause mortality in patients with acute heart failure at 30 days and 1 year after admission. Although most widely used as a marker of systolic heart failure, elevated NT-proBNP has been reported in patients with diastolic dysfunction [2]. Therefore, it is important to determine diastolic and systolic function by echocardiography. Performing echocardiography is also important for measurement of pulmonary artery pressure. Pulmonary arterial hypertension is frequently seen in rheumatic diseases and NT-proBNP levels may be a result of the increase in pulmonary pressure [3]. On the other hand, high levels of NT-proBNP can be observed in many cases which increase cardiac output and cardiac stress such as sepsis, cirrhosis, and hyperthyroidism [4]. In context, determination of liver test and thyroid hormones profile may reveal a stronger results in such a study. Furthermore, renal dysfunction may predict HF and could estimate the risk of mortality and morbidity for HF [5]. Although it is important to measure the creatinine clearance by glomerular filtration rate (GFR), they had not given information about it. There are different methods for GFR measurement in clinical practice. The Cockcroft-Gault equation and the modification of diet in renal disease (MDRD) are commonly used method for calculating the GFR. However, the Cockcroft-Gault equation may estimate lower GFR in younger age groups compared with the MDRD formula, but it can measure higher GFR in older individuals compared with the MDRD formula [6]. In conclusion, elevated NT pro-BNP may strongly predicts all-cause mortality and morbidity of patients with HF [7]. However, higher NT pro-BNP may be associated very different conditions and the pivotal roles of those factors evaluate further large-scale prospective randomized clinical trials.

Ramipril and hydrochlorothiazide treatment of hypertensive urgency in the ED To the Editor, Hypertensive urgencies are a frequent cause for consultation at the emergency department (ED). There are multiple approaches to treating this presentation, and we endeavored to assess the safety and efficacy of an oral treatment with 10 mg of ramipril and 12.5 mg of hydrochlorothiazide to treat hypertensive urgencies (which we define as systolic blood pressure of N 180 mmHg and/or diastolic blood pressure of N120 mmHg with absence of acute target organ disease in the ED) [1]. We enrolled 620 patients with hypertensive urgency prospectively and consecutively in our study. The mean age was 61.4 ± 10.7 years, 50% of patients were male, and 80% of the total number of patients had diagnosis of hypertension. All patients were discharged from the ED with 10 mg of ramipril and 12.5 mg of hydrochlorothiazide when the systolic blood pressure was b 160 mmHg and/or diastolic blood pressure was b100 mmHg [2]. There were no adverse events reported; 87% of patients were discharged after 3 ± 1.2 hours upon arrival at the ED, but 13% of patients were admitted into the coronary care unit to receive intravenous treatment [3,4]. We have concluded that 10 mg of ramipril and 12.5 mg of hydrochlorothiazide can be a safe and effective treatment for hypertensive urgency in the ED.
