Cardiology Flashcards

Q

Recall 2 observations about a person’s pulse that may be seen if they have aortic stenosis vs aortic regurgitation

A

Aortic stenosis: NARROW pulse pressure, slow rising pulse

Aortic regurgitation: WIDE pulse pressure, ‘waterhammer’ pulse (Corrigan’s pulse)

Pulse pressure = SBP-DBP (eg if BP = 120/80, PP = 40)

Q

What is the difference in cause between an S3 and S4 heart sound?

A

S3 heart sound is caused by blood filling against a non-compliant ventricle, whereas S4 is blood filling against a compliant ventricle

Q

What clinical examination findings can help differentiate aortic stenosis caused by valve sclerosis from aortic stenosis caused by HOCM?

A

In HOCM, the valsalva manoevre increases the volume of the murmur, whereas squatting decreases it

Q

By what mechanism can heart valve disease cause a parasternal heave, and which murmurs can cause this?

A

Turner’s

138
Q

In which arrhythmia is verapamil contraindicated and why?

A

Ventricular tachycardia

Verapamil is a CCB - may reduce cardiac contractility

139
Q

Recall the location on the praecordium where each valve is best auscultated

A

Aortic: Right 2nd ICS
Pulmonary: Left 2nd ICS
Tricuspid: left 4th ICS at sternal border
Mitral: left 5th ICS, MCL

140
Q

Where is aortic regurgitation best auscultated

A

Tricuspid area: left 3rd ICS parasternally (Erb’s point)

141
Q

At what point in the breathing cycle is aortic regurgitation best auscultated, and in which position?

A

End expiration
Sat up and forward
Put stethoscope at Erb’s point

142
Q

Why are right-sided murmurs louder on inspiration?

A

Increased venous return to the RHS

143
Q

Recall 2 types of murmur that are louder when there is LESS blood flow across the affected area

A

HOCM murmurs

Mitral valve prolapse

144
Q

Which murmur is best auscultated when the patient is in the left lateral decubitus position?

A

Mitral stenosis

145
Q

Which murmurs can radiate? Where do they radiate to?

A

Aortic stenosis –> carotids

Mitral regurgitation –> axilla

146
Q

Describe the meaning of each of the 6 grades of heart murmur

A

Grade 1 - Difficut to hear
Grade 2 - Quiet
Grade 3 - Easy to hear
Grade 4 - Easy to hear with a palpable thrill
Grade 5 - Easy to hear with stethoscope barely touching chest
Grade 6 - Easy to hear with stethoscope away from patient

147
Q

How does mitral stenosis vs regurgitation affect the heart structurally and why?

A

Stenosis –> atria have to work really hard to push blood through valve –> hypertrophic left artium

Regurgitation –> backflow of blood into atria stretches chamber –> left atrial dilatation

148
Q

What are the 2 main possible causes of mitral stenosis?

A

Rheumatic heart disease is the most common (learn!)

Infective endocarditis

149
Q

Why do you get a loud S1 in mitral stenosis?

A

Thickened valve needs a large systolic force to shut - once this systolic threshold is met the valve will shut very suddenly

150
Q

What is the cause of malar flush in patients with mitral stenosis?

A

Backflow of blood into the pulmonary system –> rise in CO2 and vasodilation

151
Q

What is the link between mitral regurgitation and congestive heart failure?

A

Backflow of blood –> reduced ejection fraction

–> backlog of blood waiting to pass through left side of heart

152
Q

What are the possible causes of mitral regurgitation and which of them is most common?

A
Age-related weakening is most common 
Also associated with: 
- IHD 
- Infective endocarditis

Q

What is paroxysmal nocturnal dyspnoea?

A

Waking up suddenly in the night feeling acutely SOB with a really bad cough/ wheeze
They have to get up and gasp for air
Symptoms typically improve after a few minutes

158
Q

What is the mechanism of PND (3 aspects)?

A
  1. Lying flat –> fluid settling across large surface area of lungs
  2. Respiratory centre in the brain is less responsive during sleep - so lungs can become much more congested that they would normaly do before they wake up
  3. Adrenaline levels are much lower at night so myocardium is more relaxed –> reduced CO
159
