Elevated blood pressure (BP) is frequent after acute stroke and almost 40% of patients remain hypertensive over a period of about a week. There is no data from controlled trials concerning management of hypertension in the acute phase of stroke. Theorical beneficial effects of acutely lowering BP seems lower that risk of deterioration of ischemic brain tissue. Current acute ischemic stroke guidelines suggest that unless systolic BP exceeds an cutoff of 220 mmHg or diastolic exceeds 120 mmHq, it should be tolerated, except in planned thrombolytic therapy. In case of hemorragic stroke, the cutoff should be of 185/110 mmHg. Prudence suggests that BP should be lowered carefully. In secondary prevention of stroke, the Perindopril Protection Against Recurrent Stroke Study (PROGRESS) demonstrated that a blood pressure-lowering regimen, involving a angiotensin-converting enzyme inhibitor and a diuretic, reduced the risks of stroke of 28% and of other major vascular events of 26% among individuals with a history of cerebrovascular disease. Every patient with a history of stroke should be treated with the association.

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Hypertension V: Nursing Management

The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.

Hypertension IV: Drug Therapy and Lifestyle Modifications

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
