Cardio Flashcards
Sinus tachycardia def and causes
Fast heart rate over 100bpm with normal rhythm that can be caused by anemia, CHF, pain, anxiety, exercise, and hyperthyroidism
Sinus tachycardia Sx
rate over 100, chest pain, palpitations, dyspnea
Sinus tachycardia sequelae
CHF, clots
Sinus tachycardia workup
ECG, halter monitor
Sinus tachycardia tx
beta blockers, CCB, carotid massage, adenosine for emergency rate control
aortic regurg def and causes
valvular incompetence causing backflow into the ventricle, most commonly due to rheumatic fever but can also be from infective endocarditis and congenital bicuspid valve
aortic regurg sx
HTN, dyspnea, paroxysmal nocturnal dypnea, palpitations, arrhythmias, syncope, angina, pallor, diastolic decrescendo murmur, wide pulse pressure (>40), LVH, JVD
aortic regurg sequelae
CHF
aortic regurg workup
chest xray for cardimegaly, echocardiogram
aortic regurg tx
vasodilators to decrease preload (nitro, ACE, CCB), diuresis to decrease blood volume, blood pressure, and after-load (thiazides, loops, aldosterone antagonists, ACE inhibitors)
Vascular causes of claudication
atherosclerotic disease, vasculitis (Buerger’s, Takayasu), diabetic nephropathy, venous disease (DVT, varicose veins)
neurologic causes of claudication
neurospinal disease (spinal stenosis), reflex sympathetic dystrophy
musculoskeletal causes of claudication
OA, RA, connective tissue diseases
ischemic heart disease def and causes
results from atherosclerosis of the coronary arteries causing insufficient cardiac perfusion and is usually associated with smoking, diabetes, HTN, and hyperlipidemia
ischemic heart disease sx
substernal chest pain, dyspnea on exertion, paroxysmal nocturnal dysnea, tachycardia, diaphoresis
ischemic heart disease sequelae
CHF, MI, angina, stroke
ischemic heart disease workup
cardiac catherization is gold standard, lipid panel (risk factors), ECG, echo
ischemic heart disease tx
anticoagulants to prevent thrombo (ASA, pentoxifyline), rate control to decrease cardiac demand (BB, CCB), lipid management (statins), supplemental antioxidants to reduce atherosclerosis
cardiac tamponade def
complication of pericardial effusion in which accumulation of fluid in the pericardial space restricts the heart’s ability to pump, decreasing cardiac output
cardiac tamponade sx
beck’s triad (hypotension, distended neck veins, muffled heart sounds), chest pain, tachycardia, dyspnea, tachypnea, pulsus paradoxus (inspiratory fall in systolic BP by >10mmHg), Kussmaul’s sign (increased JVP on inspiration)
cardiac tamponade sequelae
hypotension, cardiogenic shock, cardiac failure, cardiac arrest, death
cardiac tamponade workup
ECG, echo, x ray
cardiac tamponade tx
Iv fluids, pericardiocentesis, avoid vasodilators and diuretics (will further decrease venous return and thus cardiac output)
cardiac causes of chest pain
acute coronary syndrome, acute MI, angina, pericarditis, cardiac tamponade, aortic dissection, aortic stenosis
respiratory causes of chest pain
pulmonary HTN, pulmonary embolism, pneumothorax, pneumonia
gastric causes of chest pain
GERD, PUD, esophageal rupture, pancreatitis, pneumomediastinum
musculoskeletal causes of chest pain
costochondritis
Raynaud’s def
bilateral vasospastic disorder leading to intermittend attacks of pallor and cyanosis of the digits due to cold exposure. Raynaud’s phenomenon is a secondary disorder of the small blood vessels causing similar symptoms.
Raynaud’s sx
sudden onset pallor and cyanosis of the digits, discoloration of the digits, arthralgia, sclerodactyly, telangectasia, photosensitivity
Raynaud’s sequelae
ulceration, gangrene, cellulitis, osteomyelitis
