Treatment of High Blood Pressure: When Medicines Don’t Work

Treating high blood pressure can be very difficult when medications don't work. When the diastolic blood pressure is less than 80 mm Hg and the systolic blood pressure is less than 120 mm Hg, the blood pressure is considered normal. A persistent increase in blood pressure is referred to as hypertension. When the diastolic blood pressure is less than 80 mm Hg and the systolic blood pressure is between 120 and 129, the blood pressure is regarded as elevated.


According to the new guidelines released at the Scientific Sessions by the American Heart Association, the American College of Cardiology, and nine other health organizations, in Hypertension stage I, Alternatively, the diastolic blood pressure ranges from 80 to 89 mm Hg when the systolic blood pressure is between 130 and 139. Stage II of further advanced hypertension is defined as having a systolic blood pressure of at least 140 mm Hg or a diastolic blood pressure of at least 90 mm Hg.


Therapy of high blood pressure: What is the problem?

Over 85 million adults (one in every three) in the United States have hypertension, and about 20% are not aware of it. It is a main modifiable risk element for cardiovascular illness and stroke. The direct and avoiding costs of hypertension are extremely significant. Hypertension can be linked to 50% of cardiovascular diseases and 75% of strokes. High blood pressure costs the nation 46 billion dollars annually in healthcare services, medication, and missed work days. It is labeled the "silent killer ." Most of the moment, there are no clear symptoms. High blood pressure does not cause headaches or nosebleeds except in hypertension emergencies when blood pressure reaches 180/110 mm hg.



What is the treatment for high blood pressure?


The American Heart Association has created hypertension as a primary focus to seek to enhance cardiovascular death and stroke and lower cardiovascular events by 20% by 2022. The AHA is promoting evidence-based control algorithms to standardize therapy that contains lifestyle modifications in all hypertension patients. This retains weight reduction adoption of DASH eating goals by consuming a diet rich in fruit and vegetables, low in dripping fat, and low in salt information (less than 2.4gm/day). It also contains regular physical activity (brisk walk, 30 min/day) most days of the week and average alcohol consumption (2 drinks/day for men or 1 drink/day for women).


Additionally, it encourages the system level of monitoring blood pressure regulation with input to healthcare professionals, regular updating, and adopting single-pill combinations.


The amended recommendations state that individuals with stage 1 hypertension and clinical cardiovascular disease or a 10-year atherosclerotic cardiovascular risk of 10% or above, as well as those with stage 2 hypertension, should begin medical treatment. The pharmaceutical regimen should include a thiazide diuretic, calcium channel blocker, ACE inhibitor, or angiotensin receptor blocker. Increase the dose or add another medicine if the goal blood pressure is not achieved with one medication.


Only 75% of individuals with hypertension receive treatment, and only 50% have their blood pressure under control, although medications to reduce blood pressure and related cardiovascular risks have been available for years. Stroke, heart attack, heart failure, and kidney disease can all be brought on by hypertension.


Excessive blood pressure results from many causes, including 1) excessive nervous system stimulation of the heart vessels and kidney, 2) excessive display of hormones involving the vessels and kidney, or 3) stiffening of the blood vessels forcing them to lose their flexible quality. This later form of hypertension has been termed “structural hypertension .”Extreme dietary salt, increased body weight, lack of physical exercise, and excessive alcohol may contribute to hypertension. Medicines prescribed by your physician are essential to controlling blood pressure. If you have unpleasant side effects from the medications, it is important to discuss stopping or altering the medication with your physician.


New innovative medicinal approaches may be especially relevant to patients with hypertension disorders that put them at risk of primary cardiovascular affairs. Each month of available treatment is associated with around 1 day of life expectancy increase.


Therapy of high blood pressure: When medicines don’t work.


When medicines fail to lower blood pressure, we should consider “structural” hypertension. In the want of sleep apnea or renovascular condition, worsening essential hypertension or failure to reply to medications can be linked to structural changes in our large capacitance streets. Aging, smoking, and diabetes are all associated with remote or predominantly systolic hypertension (systolic BP More than 160 and diastolic BP Less Than 95) and the loss of elasticity of our major blood vessels. After age 50, hypertension is likely to be structural, and almost 70% of uncontrolled hypertension after age 65 is structural. Structural hypertension is characterized by increased arterial stiffness of the large arteries. 


In isolated systolic hypertension, large artery remodeling includes thickening of the middle layer with an enlargement of the lumen of the proximal elastic arteries such as the aorta. This remodeling and stiffening of the large arteries play a major role in augmenting the systolic and pulse pressure. The loss of aortic elasticity improves volume sensitivity. For this cause, diuretics should be our first line of therapy. 


For this investigation, we plan to investigate the development of an arteriovenous (AV-) fistula in patients with refractory, uncontrolled hypertension because diuretics are not very effective at lowering arterial volume. Making an AV- fistula decreased arterial stiffness and blood pressure in pre-dialysis patients.
