Since the new hypertension guideline published by the American Heart Association/American College Cardiology/American Society of Hypertension in 2017, the Korean Society of Hypertension and the European Society of Hypertension revised and announced new hypertension guidelines. Also the Korean Society of Hypertension published Korea hypertension fact sheet 2018, including prevalence, awareness, management status of hypertension, and their trends in Korea. Herein, I provide information on diagnosis and treatment of hypertension based on the new guidelines of the Korean Society of Hypertension.

OBJECTIVEThe analyze the correlation of heart and kidney biomarkers to different heart and kidney diseases and explore the pathogenesis and classification of cardiorenal syndrome.
METHODSThis study involved 841 consecutive patients (600 males and 241 females) admitted between January, 2008 and May, 2008, who underwent NT-ProBNP and creatinine tests during hospitalization. The patients were classified according to the clinical diagnosis at the admission and to the status of the heart and kidney biomarkers.
RESULTSThe heart and kidney biomarkers were significantly different between genders. NT-proBNP showed slight elevations in patients with atrial fibrillation, mild non-heart disease, hypertension and angina, but significant elevation in patients with severe non-heart disease. In patients with renal artery stenosis, the heart and kidney biomarkers were moderately increased, which was also seen in patients with diabetes mellitus, myocardial infarction and coronary artery bypass grafting. In dilated cardiomyopathy and rheumatic heart disease, NT-proBNP showed marked increase with only slight increase of creatinine. Patients with chronic kidney disease had the highest NT-proBNP and creatinine levels and the lowest eGFR. The heart and kidneys index increased with the severity of the disease. From Ronco type I to type IV, NT-proBNP rose gradually, but the difference was not statistically significant (P>0.05), and the type I and IV patients had the highest creatinine level; type III involved mainly acute coronary syndrome, heart failure and renal stenosis. According to a modified classification, cardiarenal syndrome was characterized mainly by a marked increase of NT-proBNP, while renalcardiac syndrome by creatinine increases (P<0.05). Acute coronary syndrome, heart failure and renal artery stenosis represented a special entity of cardiorenal syndrome.
CONCLUSIONSHeart and kidney biomarkers and clinical diagnosis are closely related. The heart and kidneys index more accurately reflects the severity of the cardiorenal syndrome. The heart and kidney biomarkers can be used in Ronco classification. The simplified classification is convenient to use and facilitates the clinical decisions of the treatment.

3.Updated Guideline for Diagnosis of Hypertension in Chronic Kidney Disease Patients: Based on 2017 ACC/AHA Hypertension Guideline
Korean Journal of Medicine 2019;94(3):263-267
Hypertension affects the majority of patients with chronic kidney disease (CKD) and increases the risk of cardiovascular disease, end-stage renal disease and mortality. Previously, many hypertension guidelines have suggested blood pressure targets in patients with CKD. Recently, the American College of Cardiology/American Heart Association 2017 Guideline for Hypertension suggests a new definition for hypertension and therapeutic targets, which were equally applicated to patients with CKD. These changes reflect the results of the Systolic Blood Pressure Intervention Trial (SPRINT) study, but the renal outcome of intensive blood pressure control was not good. Furthermore, the majority of hypertension guidelines including those of the Korean Society of Hypertension and the European Society of Hypertension have retained the traditional definition. Herein, we intend to analyze in detail the effect of intensive blood pressure control on kidney through the post-hoc analyses of the SPRINT study.

4.Management plans for populations with normal-to-hypertensive blood pressures: risks and benefits of antihypertensive drug treatment in populations previously defined as having high-normal blood pressure.
The Korean Journal of Internal Medicine 2019;34(1):44-49
Recent changes in American and European guidelines on the management of arterial hypertension have caused a considerable shift in the landscape of hypertension management. The 2017 American College of Cardiology/American Heart Association/American Society of Hypertension guideline recommends an office visit blood pressure (BP) > 130/80 mmHg as the new threshold for diagnosis of hypertension, and states that the treatment goal for all hypertensive patients should be lowered to < 130/80 mmHg. In contrast, the 2018 European guideline maintains the diagnostic threshold of hypertension at 140/90 mmHg. However, despite their differences in thresholds for diagnosis of hypertension, both guidelines are in agreement that treatment should be considered in patients with BPs in the range of 130 to 139/80 to 89 mmHg if they have high cardiovascular risk. The results from the Systolic Blood Pressure Intervention Trial (SPRINT) study and recent meta-analyses suggest that BP lowering with antihypertensive treatment may be beneficial in reducing cardiovascular event rates in subjects with high-normal BP or stage 1 hypertension according to the new American guideline. However, intensive BP lowering is associated with increased incidence of treatment-associated adverse events, and evidence suggests that BP lowering below 120/70 mmHg increases the risk of cardiovascular events. In this review, we discuss the evidence supporting antihypertensive treatment in subjects with high-normal BP and discuss the specific subgroup of subjects that might benefit from BP lowering.

5.Target Blood Pressure in Patients with Diabetes.
Journal of Korean Diabetes 2018;19(1):7-14
The recently published 2017 American College of Cardiology (ACC)/American Heart Association (AHA)/American Academy of Physician Assistants/Association of Black Cardiologists/American College of Preventive Medicine/American Geriatrics Society/American Pharmacists Association/American Society of Hypertension (ASH)/American Society for Preventive Cardiology/National Medical Association/Preventive Cardiovascular Nurses Association (2017 ACC/AHA/ASH guideline for short) lowered the threshold for diagnosis of hypertension from 140/90 mm Hg to 130/80 mm Hg. Also, the revised guideline recommends pharmacological treatment for all hypertensive patients with either previous cardiovascular disease or 10-year atherosclerotic cardiovascular disease (ASCVD) risk greater than 10%. Since most diabetic hypertensive patients have ASCVD risk greater than 10%, the guideline recommends that all diabetics with blood pressure (BP) above 130/80 mm Hg be treated both pharmacologically and with active lifestyle modification. Although the evidence suggests that intensive lowering of BP may be beneficial in diabetic patients, there is lack of evidence that pharmacologic treatment in subjects with baseline BP below 140 mm Hg is beneficial, with some studies suggesting actual potential for harm. Also, there are data to suggest a potential risk of increased risk of cardiovascular events and mortality in subjects whose diastolic BP (DBP) was lowered to below 60 mm Hg. As such, strict BP lowering may be beneficial if the target BP could be achieved without side effects such as orthostatic hypotension and decreased renal function. Also, lowering of DBP below 60 mm Hg should be avoided. Lastly, treatment should be started in subjects with baseline BP above 140/90 mm Hg until further evidence suggests otherwise.

6.New Biomarkers of Acute Kidney Injury and the Cardio-renal Syndrome.
The Korean Journal of Laboratory Medicine 2011;31(2):72-80
Changes in renal function are one of the most common manifestations of severe illness. There is a clinical need to intervene early with proven treatments in patients with potentially deleterious changes in renal function. Unfortunately progress has been hindered by poor definitions of renal dysfunction and a lack of early biomarkers of renal injury. In recent years, the definitional problem has been addressed with the establishment of a new well-defined diagnostic entity, acute kidney injury (AKI), which encompasses the wide spectrum of kidney dysfunction, together with clearer definition and sub-classification of the cardio-renal syndromes. From the laboratory have emerged new biomarkers which allow early detection of AKI, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C. This review describes the new concepts of AKI and the cardio-renal syndromes as well as novel biomarkers which allow early detection of AKI. Panels of AKI biomarker tests are likely to revolutionise the diagnosis and management of critically ill patients in the coming years. Earlier diagnosis and intervention should significantly reduce the morbidity and mortality associated with acute kidney damage.

OBJECTIVETo evaluate the value of serum brain natriuretic peptide (BNP) in the diagnosis of hyperthyroid heart disease in children.
METHODSFifty-eight children with hyperthyroidism were assigned to two groups according to their cardiac functions: hyperthyroid heart disease (n=28) and hyperthyroidism alone (n=30). Thirty healthy children served as the control group. Serum BNP level, left ventricular ejection fraction (LVEE) and E/A ratio were measured before and after treatment. The diagnostic value of BNP was evaluated in children with hyperthyroid heart disease.
RESULTSThe serum BNP level in the hyperthyroid heart disease and the hyperthyroidism alone groups before treatment was significantly higher than that in the control group (P<0.05), while the LVEF and the E/A ratio were significantly lower than those in the control group (P<0.05). Serum BNP level was positively correlated with the TT3 (r=0.801, P<0.05) and TT4 levels (r=0.578, P<0.05) and negatively with the LVEF (r=-0.48, P<0.05) and the E/A ratio (r=-0.35, P<0.05) in the hyperthyroid heart disease group. The serum BNP, TT3 and TT4 levels in the hyperthyroid heart disease and the hyperthyroidism alone groups were reduced and the LVEF and the E/A ratio increased significantly three months after treatment (P<0.05). When serum BNP level of >323.62 pg/mL was proposed as a cutoff point, the sensitivity, specificity, positive predictive value and negative predictive value were 92.86%, 90.00%, 89.66% and 93.10% respectively for the diagnosis of hyperthyroid heart disease.
CONCLUSIONSBNP may serve as a reliable marker for the diagnosis of hyperthyroid heart disease in children. Serum BNP level along with the LVEF and the E/A ratio may be useful in the evaluation of the severity and the cardiac function in children with this disease.

PURPOSE: In managing acutely dyspneic patients, differentiating the underlying disease rapidly is important but not easy. Although B-type natriuretic peptide (BNP) is generally accepted as a useful marker, inconclusive results require an emergency physician (EP) to have something more confirmative. We evaluate whether Tissue Doppler Echocardiography (TDE) performed by an EP can better discriminate between heart disease and lung disease than can BNP in the emergency department (ED). METHODS: For enrolled ED patients with acute dyspnea and unclear pathology, initial BNP level and TDE performed by EP were checked prospectively. The ratios of peak early diastolic transmitral blood flow velocity (E) versus the peak early diastolic tissue velocity over mitral annulus (Ea) on TDE were recorded. The sensitivity and specificity of tissue Doppler parameters and BNP levels for diagnosing acute heart failure were calculated and we compared the discriminatory ability of the two tools. RESULTS:49 patients (39 heart failure, 10 respiratory disease) were enrolled. The area under the ROC curves for BNP and E/Ea were 0.946 and 0.888 (p<0.001) respectively. Cutoff values were 350 pg/ml for BNP (sensitivity and specificity of 82.1% and 100%) and 9.0 for E/Ea (89.2% and 100%). Especially in the group with low BNP (<350), BNP was a poor discriminator of the underlying disease, whereas E/Ea was still effective (AUC: 0.943, p=0.021). CONCLUSION: TDE by EP is a useful tool for diagnosing acute heart failure in ED and could easily and rapidly discriminate the underlying disease of acutely dyspneic patients, especially in patients with inconclusive BNP levels.

Vitamin D insufficiency may be associated with cardiovascular (CV) mortality in HD patients. To test this hypothesis, we cross-sectionally measured 25-hydroxyvitamin D (25D), 1,25-dihydroxyvitamin D (1,25D), cardiac troponin T (cTnT), and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) in chronic HD patients. Sixty-five patients (M:F=31:34, age 52.2+/-13.2 yr, DM 41.5%) were selected. Along with the expected low levels of 1,25D, 59 (90.8%) patients had 25D insufficiency (<30 ng/mL) among whom 15 (23.1%) were 25D deficient (<10 ng/mL). The 25D levels showed a negative correlation with cTnT levels (Spearman's rho=-0.44, p<0.01) but not with NT-pro-BNP levels (Spearman's rho=-0.17, p=0.17). The 1,25D levels, however, did not show any relationship with either cTnT or NT-pro-BNP. In multivariate analysis, being male and having low levels of 25D were independent risk factors associated with cTnT elevation (beta=0.44, p<0.01 and beta=-0.48, p<0.01, respectively). In conclusion, not only 1,25D but also 25D are commonly decreased in HD patients. Lower 25D levels appear to be associated with cTnT elevation, predicting worse CV outcome, and are possible to involve cardiac hypertrophy or coronary artery disease.

10.Research advance of brain natriuretic peptide and N-terminal brain natriuretic peptide in the diagnosis and treatment of pediatric cardiovascular diseases.
Chinese Journal of Contemporary Pediatrics 2012;14(6):470-474
Brain natriuretic peptide (BNP) and N-terminal brain natriuretic peptide (NT-proBNP) are important biomarkers for pediatric cardiovascular diseases. Peptide levels are associated with age and gender. Current studies have shown that BNP and NT-proBNP are valuable in the diagnosis of heart failure, with a high specificity and sensitivity. They also contribute to differentiating heart failure from acute respiratory distress induced by simple pulmonary factors. In addition, BNP and NT-proBNP are useful in the evaluation of disease severity and treatment guidance in children with pulmonary hypertension, cardiomyopathy and Kawasaki disease. Current limitations include the relatively small sample size of the study, the detection method and a range of normal values that are not completely uniform.
