Superior vena cava Syndrome

A

Occurs when a mass, like a tumor, compresses the superior vena cava, causing venous distinction in the upper extremities and head.

Q

Hypertension

A

The pressure-natriuresis relationship shifts so that the patient excretes less sodium in the urine.

Sustained hypertension causes left ventricular hypertrophy and coronary arthrosclerosis, increasing the risk for myocardial infarction.

A

Characterized by carditis, acute migratory polyarthritis, chorea, and erythema marginatum, which occur 1 to 5 weeks after streptococcal infection of the pharynx.

Causes cardiac valve damage by an abnormal immune response.

Q

Atherosclerosis

A

Hardening of the arteries. The lining of the arteries is supposed to be smooth, so the blood can travel easily. And atherosclerosis, the linings become thick and rough. Sometimes a clot develops in socks blood flow. In the heart it is an MI, in the brain it is a stroke.

Q

Right heart failure

A

Symptoms: jugular venous distention, hepatomegaly, ankle Adema.

22
Q

Risk factors for HTN

A

Family history, low potassium intake, increased age, increased renin, obesity, low magnesium intake, increased firing of SNS, high sodium intake, cigarette smoking, high alcohol intake, glucose intolerance.

23
Q

Secondary hypertension

A

HTN caused by an underlying disease process, such as renal disease.

24
Q

Myocardial hibernation

A

Involves persistently ischemic myocardium that undergoes metabolic adaptation until the perfusion is restored

25
Q

Myocardial stunning

A

Involves temporary loss of contractile ability after perfusion has been restored.

26
Q

Dilated cardiomyopathy

A

Cardiac chamber’s are enlarged (have increased diastolic volume), and the myocardium has decreased contractility.

27
Q

Restrictive cardiomyopathy

A

Cardiac chambers have decreased diastolic volume because the myocardium is rigid and noncompliant.

28
Q

Valvular stenosis

A

Narrowing of a valve, which impedes the forward flow of blood.

29
Q

Valvular regurgitation

A

Incomplete closure of the valve, which allows blood to leak backward through the valve.

30
Q

Thromboembolus

A

A clot and a blood vessel that breaks loose and circulates.

31
Q

Venus stasis ulcer

A

Caused by Sluggish circulation from chronic venous insufficiency.

32
Q

Orthostatic hypotension

A

Is this all that blood pressure decrease of at least 20 mmHg or a diastolic blood pressure decrease of at least 10 mmHg within three minutes of standing and is a significant risk factor for falls.

33
Q

Fat embolism

A

Happens after trauma too long bones.

34
Q

Peripheral artery disease

A

Risk factors: the same as risk factors for arthrosclerosis

35
Q

Adiponectin

A

And anti-atherogenic adipokine. Decreased in people with obesity.

36
Q

Myocardial infarction

A

Can be caused by clot formation at the site of rupture of an atherosclerotic plaque, causing tissue ischemia and infarction if blood flow is not restored. Risk increases with factors that increase myocardial oxygen demand or reduce myocardial oxygen supply.

Tissue healing after an MI create a non-contractile scar.

37
Q

High-output heart failure

A

Heart failure in which the cardiac output is increased but still in sufficient to meet the bodies oxygen and nutrients needs.

38
Q

Aortic stenosis

A

Symptoms: lightheadedness with exertion. This is because the heart is unable to pump out enough excess blood to meet the body’s needs.

Associated with left ventricular hypertrophy and dilation.

39
Q

Mitral regurgitation

A

Associated with left atrial and left ventricular dilation and hypertrophy.

40
Q

Mitral stenosis

A

Associated with left atrial hypertrophy and dilation.

41
Q

Tricuspid regurgitation

A

Associated with the right atrial and right ventricular dilation and hypertrophy.

42
Q

Three causes of clot development

A

Stasis of blood, increased clotting ability, and injury to the inside of a blood vessel.

43
Q

Systolic heart failure

A

The heart has difficulty emptying it went it contracts to pump blood.

44
Q

Diastolic heart failure

A

The heart is not filled properly when it relaxes.

45
Q

Coronary heart disease

A

Risk factors: family history of heart disease, personal history of HDL, HTN, DM, high cholesterol, atherosclerotic disease and other vascular systems, history of smoking, additional physical activity, usual diet, recent stressors,

46
Q

Stable angina

A

Angina pain from mile cardio ischemia that occurs predictably with exertion and is relieved with rest or nitro

47
Q

CRP

A

A nonspecific marker of inflammation measured to assess cardiac risk.

48
Q

Aneurysm

A

Localized outpouching or dilation of a vessel wall or cardiac chamber

49
Q

Thrombus

A

A blood clot that is attached to the endothelium in a blood vessel or cardiac chamber.

50
Q

Unstable angina

A

A type of angina caused by a clot temporarily including a coronary artery, resulting before necrosis occurs.

51
Q

LDL

A

A type of lipoprotein that migrate into arterial walls in atherosclerosis.

52
Q

Plaque

A

The lesions of atherosclerosis.
