Q

hypertension

A

elevation of arterial blood pressure

22
Q

hypertensive stroke

A

a form of stoke caused by intracerebral hemorrhage in hypertensive persons, usually related to a sudden rupture of damaged brain arteries

23
Q

hypotension

A

a condition characterised by low arterial blood pressure

24
Q

lymphangitis

A

an inflammation of the lymphatic vessels, usually resulting from an acute streptococcal infection of one of the extremities

25
Q

myocardial infarct

A

ishemic necrosis of the heart muscle presenting clinically as chest pain, heart failure, or sudden death

26
Q

myocarditis

A

an inflammation of the myocardium, usually caused by viruses

27
Q

pericarditis

A

inflammation of the pericardium, usually accompanied by formation of a serous, fibrinous, or purulent exudate on its internal

28
Q

Raynauds disease

A

a disease of unknown ethology characterised by intermittent attacks of ischemia of the extremities, including fingers, toes, ears, and nose presumably as a result of vascular spasm. similar symptoms are found in persons with systemic lupus erythematous and systemic sclerosis of cryoglobulinemia, called Raynaud’s disease

29
Q

renin

A

an enzyme produced by the juxtaglomerular apparatus cells of the kidney, which increases blood pressure by acting on angiotensinogen

30
Q

rheumatic fever

A

an immunologic reaction to streptococci that affects the joints and the heart

31
Q

tetralogy of fallot

A

a congenital heart disease characterised by four specific defects, including interventricular septal defect, dextroposition of the aorta over-riding the septal defect, stenosis of pulmonary arteries, and right ventricular hypertrophy

32
Q

thrombophlebitis

A

an inflammation of thromboses veins, usually in the lower extremities

33
Q

troponin

A

a group of proteins, normally found in cardiac myocytes, that are released from damaged heart cells during an infarction. its serum concentration is elevated soon after the onset of myocardial infarction and therefore a troponin test is used for the diagnosis of myocardial infarction

34
Q

ventricular aneurysm

A

a localised dilation or saccular protrusion in the wall of the left ventricle, usually caused by scarring of a healed myocardial infarct

35
Q

ventricular rupture

A

a tear in the muscle wall of the left ventricle as a result of myocardial necrosis in an infarct. it may cause bleeding into the pericardial cavity, cardiac tamponade, and sudden cardiac death

36
Q

ventricular septal defect

A

the most common cardiac anomaly, characterised by one or more abnormal openings in the septum separating the left from the right ventricle

37
Q

Atherosclerotic aneurysms

A

are aneurysms caused by atherosclerosis and typically occur in the abdominal aorta, thus generating abdominal aortic aneurysms.

38
Q

atherosclerotic intestinal disease

A

intestinal ischemic syndrome are caused by atherosclerosis leading to narrowing or blockage of the vessels

39
Q

atherosclerotic / hypertensive renal disease

A

elevated blood pressure caused by kidney disease. some people with renal hypertension can be helped by angioplasty, stenting or surgery on the blood vessels of the kidney

40
Q

cardiomegaly

A

abnormal enlargement of the heart

41
Q

cardiomyopathy

A

chronic disease of the heart muscle

42
Q

congestive heart failure

A

aka heart failure. a condition in which the heart muscle is weakened and can’t pump as well as it usually does. the main pumping chambers of the heart (the ventricles) can change size and thickness, and either can’t contract (squeeze) or can’t relax (fill) as well as they should. this triggers fluid retention, particularly in the lungs, legs and abdomen

43
Q

coronary heart (artery) disease

A

occurs when the coronary artery clogs and narrows because of the buildup of plaque

44
Q

hemopericardium

A

refers to blood in the pericardial sac of the heart. clinically similar to pericardial effusion, and depending on the volume and rapidity with which it develops, may cause cardiac tamponade

45
Q

hypersensitivity vasculitis

A

an extreme reaction to a drug, infection, or foreign substance. it leads to inflammation and damage to blood vessels, mainly in the skin.

46
Q

hypertensive encephalopathy

A

refers to the transient migratory neurologic symptoms that are associated with the malignant hypertensive state in a hypertensive emergency. symptoms include: headache, nausea, vomiting, restlessness, confusion, seizures and coma

47
Q

myoglobin

A

a red protein containing ham, which carries and stores oxygen in muscle cells. structurally similar to a subunit of haemoglobin

48
Q

pancarditis

A

inflammation of the entire heart: the pericardium, myocardium, and endocardium

49
Q

peripheral vascular disease

A

is a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm.

50
Q

giant cell temporal arteries

A

is an inflammation of the lining of your arteries

51
Q

varicose veins

A

are swollen, twisted veins that lie just under the skin and usually occur in the legs

52
Q

vasculitis

A

inflammation of a blood vessel or blood vessels
