In medicine, systolic hypertension is defined as an elevated systolic blood pressure (SBP). [1] If the systolic blood pressure is elevated (>140) with a normal (<90) diastolic blood pressure (DBP), it is called isolated systolic hypertension . [ 2 ]
It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD). Blood pressure is often above 200/120 mmHg, however there are no universally accepted cutoff values .
Hypertension occurs in around 0.2 to 3% of newborns; however, blood pressure is not measured routinely in healthy newborns. [42] Hypertension is more common in high risk newborns. A variety of factors, such as gestational age, postconceptional age and birth weight needs to be taken into account when deciding if a blood pressure is normal in a ...
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [1] [2] It is the most common type affecting 85% of those with high blood pressure. [3] [4] The remaining 15% is accounted for by various causes of secondary hypertension. [3]
Antihypertensives are a class of drugs that are used to treat hypertension (high blood pressure). [1] Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction.
However, structural changes in the diseased heart as a result of inherited factors (mutations in ion-channel coding genes, for example) cannot explain the sudden onset of cardiac arrest. [ 60 ] In ventricular tachycardia, the heart also beats faster than normal, which may prevent the heart chambers from properly filling with blood. [ 61 ]
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]
For the treatment of primary hypertension (high blood pressure), meta-analyses of studies which mostly used atenolol have shown that although beta blockers are more effective than placebo in preventing stroke and total cardiovascular events, they are not as effective as diuretics, medications inhibiting the renin–angiotensin system (e.g., ACE ...
