Arteriosclerosis |
General term for all types of arterial changes |
|
Atherosclerosis |
Presence of atheromas in large arterieslow |
|
Low density lipoprotein |
Transports cholesterol to liver cells Contributes to atheroma formation “Bad” cholesterol |
|
High density cholesterol |
Transports cholesterol away from the peripheral cells to liver “Good” cholesterol |
|
Angina pectoris |
Deficit of oxygen to meet myocardial needs May precede MI Vasodilator may be prescribed |
|
Myocardial Infarction |
Occurs when coronary artery is totally obstructed Atherosclerosis is the most common cause Pain may radiate to left arm Troponin will be elevated |
|
Arrhythmias |
Deviations from normal cardiac rate or rhythm Reduction of efficiency of the hearts pumping cycle |
|
Sick sinus syndrome |
Alternating bradycardia and tachycardia Often requires a pacemaker |
|
Premature atrial contractions/beats |
Extra contraction or ectopic beats |
|
Atrial flutter |
Heart rate of 160-350 bpm AV node delays conduction |
|
Atrial fibrillation |
Over 350 bpm Causes pooling of blood in the atria Thrombus formation is a risk |
|
Heart blocks |
Conduction excessively delayed or stopped at AV node or bundle of his |
|
Ventricular fibrillation |
Muscle fibers contract independently and rapidly Cardiac standstill occurs |
|
Cardiac arrest |
Cessation of all heart activity |
|
Congestive heart failure |
Heart is unable to pump out sufficient blood to meet metabolic demands |
|
Ventricular septal defect |
Most common congenital heart defect Opening in the interventricular septum |
|
Valvular defects |
Usually a affects aortic and pulmonary valves Stenosis or valvular incompetence |
|
Tetralogy of fallot |
Blue baby syndrome Four abnormalities Pulmonary stenosis, VSD, Dextroposition of the aorta, Right ventricular hypertrophy |
|
Rheumatic fever |
Acute systemic inflammatory condition Inflammation of the heart Red streaks on the side |
|
Infective endocarditis |
Subacute- streptococcus viridans Acute- staphylococcus aureus, worse than subacute, vegetative valves |
|
Petcatditis |
Inflammation of the pericardium Usually secondary to another condition |
|
Primary hypertension |
Above 140/90 Increased arteriolar vasoconstriction Damage to arterial walls |
|
Secondary hypertension |
Results from renal or endocrine disease |
|
Malignant hypertension |
Severe and rapidly progressive with many complications Diastolic is extremely high |
|
Peripheral vascular disease |
Disease in arteries outside the heart Most common in abdominal aorta, carotid arteries, femoral and iliac arteries |
|
Aortic aneurysm |
Localized dilation and weakening of arterial wall Bulging wall on the side |
|
Varicose ceins |
Irregular, dilated, tortuous areas of superficial veins |
