Cardiovascular Flashcards
What is acute myocardial infarction
known as ST elevation myocardial infarction (STEMI) and acute coronary syndrome (ACS)
A classic case for MI
A middle-aged or older man c/o gradual onset of intense and steady chest discomfort or pain that is described as squeezing, tightness, crushing, heavy pressure (an elephant sitting on my chest), or band-like
What is MI characteristics
pain or discomfort may radiate to the left side of the neck, jaw, and left arm.
diaphoretic with cool, clammy skin
Women & elderly present with SOB, dyspnea, weakness, nausea and vomiting, fatigue, and syncope.
could also have back pain
CHF sxs
older patients complains of acute onset of dyspnea, fatigue, dry cough, and swollen feet and ankles
CHF characteristics
Lung exam reveal crackles on both the lung bases along with an S3 heart sound.
CHF risk factors
HX of CAD, angina, prior MI, previous episode of CHF
What is infective endocarditis
Known as bacterial endocarditis
Patient presentation with endocarditis
patient presents with fever, chills, and malaise that is associated with onset of a new murmur
Endocarditis skin findings
Found mainly on the fingers/hands and toes/feet
Known as sublingual hemorrhages (splinter hemorrhages on the nail bed)
Petechiae on the palate
painful violet- colored nodes on the fingers or feet (Osler nodes)
Nontender red spots on the palms/soles (Janaway lesions)
fundoycopic exam- rote spots or retinal hemorrhages
Abdominal Aortic Aneurysm (AAA)
Presentation
sudden onset of severe, sharp excruciating pain located in the abdomen, flank, or back.
accompanied by a distended abdomen and abnormal vital signs (hypotension)
AAA risk factors
older male patients who are smokers with hypertension are at higher risk
Chest x-ray- widened mediastinum, tracheal deviation, and obliteration of aortic knob
where is apical impulse located
5th intercostal space by the midclavicular line on the left side of the chest
what can cause displacement of the point of maximal impulse
Severe left ventricular hypertrophy and cardiomyopathy (PMI displaced laterally on the chest, larger in size (3 cm
Pregnancy 3rd trimester-PMI located slightly upward on the left side of the chest, may hear S3 heart sound during pregnancy
Where does deoxygenated blood enter the body
enters the heart through superior vena cava and inferior vena cava
then flows through right atrium>tricuspid valve>right ventricle>pulmonic valve>pulmonary artery>the lungs>alveoli
where does oxygenated blood exit the body
exits the lungs through the pulmonary veins and enters the heart
Systolic murmurs
MR.ASS (mitral regurgitation/aortic stenosis-systolic)
Diastolic murmurs
MS.ARD (mitral stenosis/aortic regurgitation =diastolic
Mitral area
AKA apex or the apical area of the heart
5th left ICS (8-9cm from the midsternal line and slightly medial to the midclavicular line
PMI/apical pulse is located here
Aortic area
2nd ICS to the right side of the upper border of the sternum
location also described as 2nd ICS by the right side of the sternum at the base of the heart. Also described as a murmur that is located on the right side of the upper sternum
Erb’s point
located at 3rd & 4th ICS on the left sternal border
MR.ASS (systolic murmurs mnemonics)
Described as occurring during S1, or as holosystolic, pansystolic, early systolic, late systolic, or midsytolic murmurs
louder and can radiate to the neck or axillae
MS.ARD (diastolic murmurs mnemonics)
Diastole AKA as the s2 heart sound, early diastole, late diastole, or middiastole
indicative of heart disease
indicated abnormal
Grade I heart murmur
very soft murmur heard only under optimal conditions
Grade II heart murmur
Mild to moderate loud murmur
Grade III heart murmur
loud murmur that is easily heard once the stethoscope is placed on the chest
Grade IV heart murmur
louder murmur, 1st time that a thrill is present, thrill is a palpable murmur
Grade V heart murmur
very loud heart murmur heard with edge of stethoscope off chest. Thrill is more obvious
Grade VI heart murmur
murmur is so loud that it can be heard even with the stethoscope off the chest. thrill is easily palpated
R/O AAA in an older male who has a pulsatile abdominal mass that is more than 3cm in width, what test is ordered
Abdominal ultrasound and CT
Mnemoic (MOTIVATED APPLES)
Motivated M-mitral valve T-tricuspid valve AV-atrioventricular valves (lub sound of Lub-dub), closure of the mitral and tricuspid valves
Apples A-aortic valve P-pulmonic valve S-semilunar valve (dub sound of Lub-dub), closure of the aortic and pulmonic valves
S3 sound indicates what heart disease
CHF
S4 sound indicates what heart disease
LVH
What is the most common cardiac arrhythmia in the United States
Atrial fibrillation
Risk factors for atrial fibrillation
HTN, CAD, ACS, caffeine, nicotine, hyperthyroidism, alcohol intake (holiday heart), heart failure, LVH, pulmonary embolism (PE), chronic obstructive pulmonary disease (COPD), sleep apnea, paroxysmal AF
AF classic case
patient reports the sudden onset of heart palpitations accompanied by feelings of weakness, dizziness, dyspnea/dyspnea on exertion, and reduction in exercise capacity. May complain of chest pain and feelings of passing out (presyncope to syncope). Rapid and irregular pulse may be more than 110 beats/min with hypotension.
