    en.wikipedia.org/wiki/Hypertensive_heart_disease

    In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...

    en.wikipedia.org/wiki/Atrial_fibrillation

    Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]

    Autonomic dysreflexia (AD) is a potentially fatal medical emergency classically characterized by uncontrolled hypertension and cardiac arrhythmia. [2] [3] [4] AD occurs most often in individuals with spinal cord injuries with lesions at or above the T6 spinal cord level, although it has been reported in patients with lesions as low as T10. [5]

    Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.

    en.wikipedia.org/wiki/Clinical_Care...

    Codes based on ICD-10 (WHO, 1992) structure for information exchange promoting interoperability. Uses a coding structure of five alphanumeric digits to link the two CCC System terminologies to each other and to map to other EHR/HIT systems. Designed for determining workload (productivity), resources (needs), outcomes (quality), and care costs.

  8. Fibrillation - Wikipedia

    en.wikipedia.org/wiki/Fibrillation

    There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.

    Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications.
