Cardiology Flashcards
Where is the S1 auscultated?
Mitral/Tricuspid close
Aortic/Pulmonic open
Where is S2 auscultated?
Aortic/Pulmonic closure
Mitral/Tricuspid open
What is Systole?
Period between S1 and S2
What is Diastole?
Period between S2 and S1
When is S3 auscultated?
Auscultated when there is increased fluid in the heart
When is S4 auscultated?
Auscultated when the heart is stiff
Murmur grading
I/IV: Barely auscultated
II/IV: Faintly heard
III/IV: Loud
IV/VI: Loud with thrill
V/VI: Auscultated with part of the stethescope
VI/VI: Loudest
Mitral Stenosis Murmur
Loud S1, low pitched, mid distolic
Mitral Opening Snap and Diastolic Murmur
Mitral Regurgitation
Systolic murmur at the 5th ICS MCL
Early Systolic Murmur
Aortic Stenosis
Systolic, rough, harsh murmur
Systolic Murmur with Absent S2
Aortic Regurgitation
Diastolic, blowing murmur at the 2nd left ICS
Early Diastolic Murmur
Where is a Mitral Murmur?
In the apex of the heart located in the 5th ICS
Where is a Aortic Murmur?
In the base of the heart located between the 2nd and 3rd ICS
What valvular diseases can be auscultated during diastole?
Mitral
Stenosis
Aortic
Regurgitation
Diastolic
What valvular disease can be auscultated during systole?
Mitral
Regurgitation
Aortic
Stenosis
Systolic
What is Heart Failure?
A condition that lowers cardiac output leaving it unable to meet the needs of the body
What are the types of of Heart Failure?
HFrEF
HEmEF
HFpEF
Acute
Chronic
What is HFrEF?
EF less than 40%
Inability to contract
What is HFmEF?
EF between 40-50%
What is HFpEF?
EF greater than 50%
Inability to relax and fill
What is AHF?
Abrupt onset of heart failure usually because of MI or valve rupture
What is CHF?
Develops as a result of inadequate compensation that have been used over a period of time to improve cardiac output
Clinical manifesations of acute left sided heart failure
Dyspnea
Coarse rales
Wheezing
Frothy cough
S3
Mitral regurgitation murmur
Clinical manifestations of chronic right sided heart failure
JVD
Hepatomegaly
Splenomegaly
Dependent edema
Paroxysmal nocturnal dyspnea
Appears chronically ill
Diffuse chest wall heave
Displaced PMI
Abdominal Fullness
Fatigue
S3 and/or S4
NYHA Class One
No limitation of physical activity
NYHA Class Two
Slight limitation of physical activity, but comfortable at rest
NYHA Class Three
Moderate limitation of physical activity, but comfortable at rest
NYHA Class Four
Unable to carry out physical activity and symptoms do not go away with rest
Laboratory/Diagnostics
- ABG: Hypoxemia and Hypocapnia
- Elevated BNP
- CXR has Pulmonary Edema and Effusion
- Echo
- ECG may show deviation or underlying problem
Nonpharmacologic intervention for heart failure
- Sodium restriction
- Rest/activity balance
- Weight reduction
What are the pharmacologic interventions for congestive heart failure?
- Diuretic.
- Angiotensin, converting enzyme inhibitor, or angiotensin II receptor blocker
- Beta blocker.
- Entresto
- Digoxin
- Anticoagulation therapy for atrial fibrillation
What is a cardiomyopathy?
A cardiomyopathy is any disorder that affects the heart muscle
What are the different types of cardiomyopathies?
- Dilated cardiomyopathy
- Hypertrophic cardiomyopathy
- Restrictive cardiomyopathy
- Arrhythmogenic right ventricular dysplasia 
- Transthyretin amyloid cardiomyopathy
What is dilated cardiomyopathy?
Dilated cardiomyopathy is dilation of the heart muscle
What is hypertrophic cardiomyopathy?
Hypertrophic cardiomyopathy he is hypertrophy of the left, and sometimes the right ventricle
What is restrictive cardiomyopathy?
Restrictive cardiomyopathy is scarring and stiffening of the heart muscle
What are the signs and symptoms of cardiomyopathy?
Signs and symptoms of cardiomyopathy is similar to congestive heart failure
Acute management of heart failure
- Manage ABC’s
- Preload and afterload reduction with vasodilators
- Inhibition of neurohormonal activation
Routine management of heart failure
- Start beta blockers once euvolemic
- Diuretic.
- ACEi/ARB
Inpatient management of pulmonary edema
- Oxygen at 1 to 2 L
- Please patient and sitting or semi-Fowlers
- Morphine 2 to 4 mg IV push
- Furosemide 40 mg IV up to 80 mg over 20 minutes
- If cardio index is low, use dobutamine
- If SBP is low, use dopamine.
What are the two types of hypertension?
- Primary is in 95% of all cases.
- Secondary is in 5% of all cases, and due to estrogen, renal disease, pregnancy, endocrine disorder, renal artery stenosis
What modifiable risk factors increase blood pressure?
- Smoking
- Obesity
- Excessive alcohol intake.
- NSAIDS
What are the signs and symptoms of hypertension?
- Often silent or none
- Elevated blood pressure
- Headache.
- Epistaxis
- Dizziness.
- Lightheadedness
- S4
- Chest pain
Laboratory and diagnostic test for hypertension
- BMP
- Chest x-ray
- Plasma aldosterone
- Cortisol level
- Urinalysis
- Complete blood count.
- Calcium (Hypercalcemia causes increased vascular resistance)
- Phosphorus (Hyperphosphotemia causes increased vascular resistance)
- Uric acid
- Cholesterol
- Triglycerides
- ECG 
What is a normal blood pressure?
SBP <120 and DBP <80
