pp. 1729-1738

The revision committee of the 2019 Thai Guidelines on the Treatment of Hypertension has reviewed new developments in the body of knowledge, together with the expertise in real-life clinical practice and evidence collected from clinical studies worldwide. The guidelines consist of newly highlighted key topics to ensure the guidelines remain up to date, user friendly, and suitable for the country’s context. The guidelines still maintain the current office blood pressure (BP) cut-off point of 140/90 mmHg for the diagnosis of hypertension. The use of out-of-office BP measurements, including home BP monitoring (HBPM) or ambulatory BP monitoring (ABPM), is also advocated to confirm the diagnosis of hypertension. Target BP levels depend on the age of the patients, such as 120 to 130/70 to 79 mmHg for patients aged 18 to 65 years old, or 130 to 139/70 to 79 mmHg for patients over 65 years of age. There are five main groups of antihypertensive medication, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, calcium-channel blockers, and thiazides or thiazide-like diuretics. Two types of medications should be started for most patients, except for frail elderly patients, patients with a relatively low initial BP of 140 to 149/90 to 99 mmHg, and low-risk patients, in which only one type of starting medication should be selected. Medication that involves a combination of two types in one pill should ideally be selected. Keywords: Hypertension; Guidelines; Thailand

We sought to assess the association between common antihypertensive drugs and the risk of incident cancer in treated hypertensive patients. Using the Korean National Health Insurance Service database, the risk of cancer incidence was analyzed in patients with hypertension who were initially free of cancer and used the following antihypertensive drug classes: Angiotensin-converting enzyme inhibitors (ACEIs); angiotensin receptor blockers (ARBs); beta blockers (BBs); calcium channel blockers (CCBs); and diuretics. During a median follow-up of 8.6 years, there were 4513 (6.4%) overall cancer incidences from an initial 70,549 individuals taking antihypertensive drugs. ARB use was associated with a decreased risk for overall cancer in a crude model (hazard ratio (HR): 0.744, 95% confidence interval (CI): 0.696–0.794) and a fully adjusted model (HR: 0.833, 95% CI: 0.775–0.896) compared with individuals not taking ARBs. Other antihypertensive drugs, including ACEIs, CCBs, BBs, and diuretics, did not show significant associations with incident cancer overall. The long-term use of ARBs was significantly associated with a reduced risk of incident cancer over time. The users of common antihypertensive medications were not associated with an increased risk of cancer overall compared to users of other classes of antihypertensive drugs. ARB use was independently associated with a decreased risk of cancer overall compared to other antihypertensive drugs.

The effective treatment of hypertension is a major factor in the declining incidence of stroke in North America. There are subsets of patients, however, in which antihypertensive therapy may actually cause cerebral ischemia and infarction. Elderly patients and those with malignant hypertension, acute stroke, and occlusive cerebrovascular disease appear to be the populations at greatest risk of iatrogenic stroke. This article reviews the effect of beta-blockers, angiotensin-converting enzyme inhibitors, direct vasodilators, and calcium-channel blockers on cerebral blood flow in various populations. Although many investigations have been performed, it remains difficult to predict the risk of cerebral hypoperfusion due to antihypertensive medication in an individual patient. It is best for practitioners to be aware of the patient populations at risk and treat high blood pressure cautiously in these patients.

The treatment of migraine depends on the frequency, severity and concomitant diseases. There are several specific drugs developed for migraine prevention in addition to the additive antimigraine effects of some other non-specific drugs. The aim of this literature-based review is to summarize the possible antimigraine properties of different antihypertensive agents (beta-blockers, calcium channel blockers, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, etc.) focusing on the possible side effects (avoidance of beta blockers in the absence of heart disease, possible antiparkinson effect of calcium channel blockers, additive effect of drugs modifying the renin-angiotensin system activity, etc.). Current evidence supports the use of angiotensin converting enzyme inhibitors (mainly lisinopril) and angiotensin receptor blockers (mainly candesartan) for long-term migraine prevention and blood pressure control. Long-term beta-blocker treatment should be avoided in the absence of ischemic heart disease due to possible unfavourable cardiovascular effects. Orv. Hetil., 2015, 156(5), 179–185.

Objective: To evaluate national antihypertensive medication use we collected data from 2003–2006 and compared it to previously collected data from 1999 –2002. We examine the cost implications of shifts in antihypertensive medications prescribed. Methods: National VA pharmacy data were used to determine the use of beta blockers (BB), calcium channel blockers (CCB), thiazide diuretics (TD) alone or with K sparing diuretics, angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARB), and combinations of the aforementioned classes for 2003–2006. Total number of treatment days, determined from days supply of the prescription, was used to determine patterns of use over time. Results: Antihypertensive medication use in the VA represented more than 1.5 billion days in 2006 and increased 2.5 fold from the 577 million estimated for 1999. ACEI were most commonly used, representing 31.8% and 31.7% of treatment days in 1999 and 2006, respectively. In the ACEI class lisinopril is the most commonly used drug. Increases in use from 1999 to 2006 were 21.2% to 25.2% for BB, 14.4% to 17.8% for TD, and 1.2% to 5.2% for ARB. Decreases in use from 1999 to 2006 were 26.7% to 17.6% for CCB. The decline in CCB was inversely correlated to the increase in BB or TD (p<0.001). Shifts in medication use are estimated to save the VA $33 million annually. Conclusions: ACEI remain the most prescribed antihypertensive drug class in the VA, followed by BB, TD, CCB, and ARBs. TD use shows a slow steady increase while CCB use continues to decline. These findings suggest that VA has increasing adherence to JNC7 and VA HTN guidelines.

Cardioprotective drugs are important in the treatment of patients at risk for or with documented cardiovascular disease. Beta-blockers are indicated after acute coronary syndromes, stable coronary artery disease, heart failure, and arrhythmias. Angiotensin-converting enzyme inhibitors (ACEi) are important in congestive heart failure, stable angina, post-acute myocardial infarction, and secondary prevention after any event or revascularization. Angiotensin receptor blockers are mainly alternative drugs for the same indications in case of intolerance to ACEi. Calcium channel blockers are first line medication for patients with isolated systolic hypertension, black people, and during pregnancy, in the presence of intermittent claudication, asymptomatic atherosclerosis, or metabolic syndrome. A polypill is a combination pill in which multiple medications effective in the prevention of cardiovascular disease (for example statins, antihypertensives, and aspirin) are put together in a single pill.

Background: The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. However, approximately half of AVFs fail to mature. The use of angiotensin converting enzyme inhibitors (ACE-Is), angiotensin receptor blockers (ARBs), and calcium channel blockers (CCBs) exerts favorable endothelial effects and may promote AVF maturation. We tested associations of ACE-I and ARBs, CCBs, beta-blockers, and diuretics with the maturation of newly created AVFs. Methods: We evaluated 602 participants from the Hemodialysis Fistula Maturation Study, a multi-center, prospective cohort study of AVF maturation. We ascertained the use of each medication class within 45 days of AVF creation surgery. We defined maturation outcomes by clinical use within 9 months of surgery or 4 weeks of initiating hemodialysis. Results: Unassisted AVF maturation failure without intervention occurred in 54.0% of participants, and overall AVF maturation failure (with or without intervention) occurred in 30.1%. After covariate adjustment, CCB use was associated with a 25% lower risk of overall AVF maturation failure (95% CI 3%–41% lower) but a non-significant 10% lower risk of unassisted maturation failure (95% CI 23% lower to 5% higher). ACE-I/ARB, beta-blocker, and diuretic use was not significantly associated with AVF maturation outcomes. None of the antihypertensive medication classes were associated with changes in AVF diameter or blood flow over 6 weeks following surgery. Conclusions: CCB use may be associated with a lower risk of overall AVF maturation failure. Further studies are needed to determine whether CCBs might play a causal role in improving AVF maturation outcomes.

The world population is aging and the number of old people is continuously increasing. Arterial structure and function change with age, progressively leading to arterial stiffening. Arterial stiffness is best characterized by measurement of pulse wave velocity (PWV), which is its surrogate marker. It has been shown that PWV could improve cardiovascular event prediction in models that included standard risk factors. Consequently, it might therefore enable better identification of populations at high-risk of cardiovascular morbidity and mortality. The present review is focused on a survey of different pharmacological therapeutic options for decreasing arterial stiffness. The influence of several groups of drugs is described: antihypertensive drugs (angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, calcium channel blockers, beta-blockers, diuretics, and nitrates), statins, peroral antidiabetics, advanced glycation end-products (AGE) cross-link breakers, anti-inflammatory drugs, endothelin-A receptor antagonists, and vasopeptidase inhibitors. All of these have shown some effect in decreasing arterial stiffness. Nevertheless, further studies are needed which should address the influence of arterial stiffness diminishment on major adverse cardiovascular and cerebrovascular events (MACCE).

Objective: The objective of this study is to evaluate the antihypertensive drug usage and dosage differences between geriatric and non-geriatric diabetics with reference to the duration of hypertension and creatinine clearance (Crcl).Methods: In this observational study, patients with type 2 diabetes mellitus were grouped into geriatric (age ≥60 years) and non-geriatric (age <60 years). Patients’ demographic data, duration of hypertension, drugs prescribed, and serum creatinine were recorded after the patients had a stabilized antihypertensive dose for 6 months. Crcl was calculated using Cockcroft–Gault formula. The dosages of antihypertensives were converted into equivalent doses for easy comparison within a group. For angiotensin-converting enzyme inhibitors (ACEIs), enalapril was considered as prototype, and for angiotensin receptor blockers (ARBs) losartan, beta-blocker atenolol, and calcium channel blockers (CCBs), amlodipine was considered as prototype. Univariate analysis was done for comparison of drug doses between groups.Results: A total of 336 diabetics with hypertension were included, of which 252 were geriatric and 84 non-geriatric. Duration of hypertension was expectedly longer in the geriatric group (8.40±7.26 vs. 5.46±5.67; p=0.001). Systolic blood pressure was higher in geriatrics (137.14±13.51 vs. 133.38±12.49; p=0.01). When adjusted for the duration of hypertension and Crcl, there were no significant differences in the mean converted equivalent doses of beta-blockers, CCBs, ARBs, and hydrochlorothiazide between geriatrics and non-geriatrics. However, statistically significant lower converted equivalent doses of all ACEIs were needed in geriatrics compared to non-geriatrics, when adjusted for duration of hypertension and Crcl. Enalapril required 20.57% and ramipril required 18.36% dose reduction in geriatrics compared to non-geriatrics.Conclusion: A 20% dosage reduction is needed for ACEIs in the elderly.
