Epidemiological transition leads to change disease patterns from communicable diseases to non-communicable diseases . The occurrence of this epidemiological transition is due to changes in socioeconomic, environmental, and population structure. People have adopted an unhealthy lifestyle, such as smoking, lack of physical activity, and high-fat/alcohol consumption. The unhealthy lifestyle is thought to be a risk factor for non-communicable diseases. The World Health Organization estimates that by 2020 non-infectious diseases will account for 73% of deaths and 60% of all morbidity in the world. It is estimated that the most affected countries are developing countries, including Indonesia .
Hypertension is one of the non-communicable diseases that are common in everyday clinical practice. Data of Riset Kesehatan Dasar 2013 shows that the prevalence of hypertension in Indonesia is 25.8% . Hypertension has effects on many target organs such as the heart, brain, kidney, and blood vessels .
Early detection, such as regular blood pressure measurement and appropriate management, can reduce complication risk. Hypertension can attack all ages, but older people are more common to have the disease. Hypertension in the elderly requires special treatment because there is an interaction between hypertension and cardiovascular risk factors [5,6]. This is confirmed by results of Hypertension in the Very Elderly Trial (HYVET) and The Systolic Blood Pressure Intervention Trial (SPRINT) study which state that management of hypertension in elderly patients needs to be distinguished from adult patients to reduce morbidity and mortality [7,8,9]. This paper compares some articles from international journals which explain about the treatment of hypertension in elderly.
Hypertension in elderly needs to be discussed because it often finds cases of mild hypertension in elderly that does not get any treatment. Besides, the blood pressure target that has to be achieved sometimes confuses the clinicians. Hopefully, this paper can provide detail information about the management of hypertension in the elderly.
This article was created to discuss some articles of international journals on the treatment of hypertension in the elderly. The authors feel the need to discuss this because during this understanding of the community often find it common when found high blood pressure in the elderly, so no treatment is done. Target blood pressure to be achieved even sometimes confuse the clinicians. It is hoped that this paper can provide new and detailed information about the management of hypertension in the elderly, both medical and non-medical procedures.
This paper used systematic review based on the Preferred Reporting Items for Systematic Review and Meta Analyzes Statement (PRISMA) 2009 (10).
Search strategy (Literature search and literature selection)
Literatures are searched by using electronic databases such as Springer Link, Proquest, and Google Scholar with the keyword "hypertension in elderly patients" and using published journals from 2010 to 2016. Inclusion criteria are all articles from various countries about hypertension in elderly, in English, has a citation, and published in 2010-2016 while the exclusion criteria are articles that are not relevant to the topic of hypertension in the elderly.From 3 electronic databases f,from 2010 to 2016, researchers obtained 991 journal articles consisting of 40 articles from Springer Link, 141 articles from ProQuest, and 810 articles from Google Scholar. Firstly, the articles were filtered by keyword, then title, inclusion and exclusion criteria and finally researchers assess the full article. There were seven articles relevant to the topic consisting of research articles, meta-analysis and systematic review (Figure 1).
Management of hypertension in the elderly is same as a management in an adult patient, which is preceded by a non-medical therapy that is lifestyle modification, combined with the management of antihypertension drug therapy [7,8,11,12]. Hypertensive patients are encouraged to reduce salt/sodium and alcohol consumption [7,12]. Smoking as a risk factor for cardiovascular disease also needs to be stopped. Patients also need to reduce stress because it can also trigger a rise in blood pressure . Other examples of lifestyle modification are weight loss and regular physical activity [7,8,12]. Non-medical therapy can reduce the consumption of anti-hypertension drugs . Anti-hypertension drugs are given according to each patient's condition and are not age-based [6,12]. Treatments that can be given are drugs from the class of ACE inhibitors, angiotensin receptor blockers (ARBs), calcium channel blockers, beta-blockers, and diuretics . The use of diuretics is not recommended for patients with electrolyte disorders, calcium antagonists may be administered to patients with arterial dysfunction, but should be avoided by patients with left ventricular dysfunction. For patients with diabetes can be given ACE inhibitors . Compared with diuretics, ACE inhibitors have a better cardiovascular effect and reduce the risk of kidney disease . From the results of HYVET research, the combination of an anti-hypertension drug indapamide SR 1.5 mg perindopril 2-4 mg reduced SBP by 17 mmHg and DBP 7 mmHg compared with placebo in systolic and diastolic hypertensive patients. In ISH patients, the effects of both drugs decreased SBP 19.3 mmHg and DBP 2 mmHg .
From the journals above, there are differences regarding blood pressure that begins to be treated with medication and blood pressure target to be achieved. There are statements to start anti-hypertension drug therapy at blood pressure 140/90 mmHg or 130/85 mmHg when there are complications of diabetes, kidney disease, and cardiovascular . Meanwhile, the others only pay attention to SBP 140 mmHg . Systolic blood pressure reduction target also varies, which is 140 mmHg and up to 120 mmHg [6,14]. Systolic blood pressure 150 mmHg is still acceptable in conditions in which patients already get a combination of 4 types of anti-hypertension drugs; there are unwanted drug side effects, and DBP decreases to 65 mmHg . Things to consider when administering anti-hypertension drugs are side effects such as orthostatic hypotension [7,11]. Polypharmacy also often occurs because elderly patients usually consume drugs for other diseases therapy . Water intake should be monitored to avoid electrolyte disturbance .
Treatment of anti-hypertension drugs in elderly starts at blood pressure 140/90 mmHg (130/85 mmHg if there is a complication of diabetes, kidney disease, and cardiovascular). The optimum target of systolic blood pressure is 120 - 140 mmHg and diastolic blood pressure is not less than 65 mmHg. Anti-hypertension drugs are adjusted to comorbidities and patient response. Lifestyle modification is needed to reduce cardiovascular risk and reduce the amount of drug consumed.
