diseases
- Rheumatic fever
- signs and symptoms
- major
- Arthritis
- carditis
- sydenham
chorea
- erythema
marginatum
- Subcutaneous
nodules
- minor
- fainting (syncope)
- occurs when the brain stops
functioning properly because of a
sudden decrease in blood flow
- pre-syncope
- feeling losing of consciousness or
blacking out due to cardiac problems
- Arthralgia
- fever
- pallor
- anorexia
- acute RF
- an inflammatory disease that is most
common in 5 to 15 years old children
- cause :Group A
streptococcus
- chronic rheumatic heart disease
- complications:
- valve
stenosis
- arrhythmia
- heart
failure
- Endocarditis
- infective endocarditis
- predisposing factors
- RHD
- congenital heart disease
- Prosthetic Valve
- IV drug abuse
- pathophysiology
- endothelial erosion>sterile micro
thrombi formation>bacteremia>
microorganism
adhesion>vegetations
- acute
- staph aureus
- affects normal valves
- destruction of the valve
- subacute
- strep. viridians
- affects abnormal valves
- no destruction of the valve
- C\P
- fever
- weakness
- complications
- glomerulonephritis
- thromboembolism
- NBTE
- libman- sack
- pathophysiology
- delayed immune response to infection
with group A beta hemolytic strep. which
induces immunological damage in heart
valves, joints &brain
- treatment
- antibiotics
- penicillin
- Anti-inflammatory drugs
- naproxen
- aspirin
- investigations
- high ESR
- elevated C active
protein
- throat culture-GABH
strep
- ASO titer
>200
- ECHO
- edema, MR, LA,LV dilation
- ECG
- prolonged P R interval, ST depression
- heart
- anatomy
- cardiac cycle
- 1st diastolic period
- the atria and ventricles are relaxed and
the atrioventricular valves are open
and RA is filled.
- 1st systolic period
- the right ventricle is filled with
blood passed on from the right
atrium and it contracts
- 2nd diastolic P.
- the semilunar valves close and
the atrioventricular valves open and the
blood moves to the lung to be oxygenated.
- 2nd systolic P
- the atrioventricular valves close and
the semilunar valves open and the left
ventricle is pumped to the aorta
- murmurs
- heart sounds produced when
blood flows across one of the
valves
- Innocent murmurs:
- fever
- pregnancy
- physical activities
- hyperthyroidism
- abnormal
- systolic
- aortic stenosis, MR, MV prolapse, tricuspid insufficiency
- diastolic
- aortic insufficiency, mitral stenosis
- normal sounds
- s1:closure of Mitral, Tricuspid valves
- S2 closure of Pulmonic, Aortic valves
- examination of CVS
- history taking
- inspection
- eyes: xanthelasma
- chest: pigeon chest
- skin: cyanosis, clubbing,Xanthomas, edema
- JVP
- palpitation
- thrill, apex beat, size of LV
- pulse: dorsalis pedis, posterior tibial P
- Auscultation
- Aortic stenosis
- causes:
- congenital bicuspid aortic valve
- calcific valvular disease
- risk factors
- smoking
- diabetes
- hypertension
- renal insufficiency
- male
- hyperlipidemia
- pathophysiology
- obstruction of LV>LV hypertrophy>aortic
pressure is low>LV compliance> elevated
LV contraction > MI> congestive HF.
- signs &symptoms
- dsyonea
- small volume pulse
- angina
- stable
- unstable
- Variant
- Microvascular
- Atypical
- mid-diastolic click murmur
