Left heart failure
- Causes: systemic hypertension, ischemic heart disease, valvular disorders (mitral and aortic stenosis and regurgitation), cardiomyopathy
- Presentation: breathlessness, orthopnea, paroxysmal nocturnal dyspnea
- Findings: tachypnea, tachycardia, S3 gallop rhythm, bibasilar inspiratory lung crepitations. When severe: Cyanosis, pink frothy sputum, extensive crepitations
Right heart failure
- Causes: secondary to left heart failure, chronic obstructive pulmonary disease, atrial septal defect
- Presentation: due to fluid retention, breathlessness and swelling of legs which may extend to ascites
- Findings; elevated JVP, large liver, ascites, cardiac cachexia (skeletal muscle loss) peripheral edema
Cardiac Tamponade
Findings: cold extremities, tachycardia, pulsus paradoxus (decrease pulse amplitude or fall in systolic blood pressure greater than 10 mm Hg) with inspiration, low blood pressure, markedly raised JVP, positive Kussmaul sign (JVP elevated further in inspiration), muffled heart sounds, clear lung fields.
Aortic stenosis
- Causes: congenital, congenital bicuspid vale with premature calcification, calcific calcification in a normal aortic valve, rheumatic aortic stenosis
- Presentation: breathlessness, chest pain dizziness or syncope, all on exertion
- Findings: slow rising pulse, thrusting or heaving apex beat (LVH), harsh loud ejection systolic murmur, heard best left mid parasternal, right second interspace or apex
- A2 maybe soft or absent
- crescendo-decrescendo murmur
Aortic Incompetence
- Causes: dilated aortic root (hypertension, Marfan‟s, ascending aortic aneurysm), abnormal aortic valve (rheumatic heart disease, endocarditis)
- Presentation: exertional breathlessness
- Findings; collapsing pulse, wide pulse pressure (>90 mm Hg) (Corrigan‟s sign, de Musset‟s sign, Quinke‟s sign, pistol shot femorals, Duroziez‟s murmur), early diastolic decrescendo murmur along the left sternal border or right sternal border

Hypertrophic cardiomyopathy
- Cause: genetic, resulting in asymmetric hypertrophy of left ventricular myocardium especially the septum
- Presentation: exertional breathlessness, chest pain, dizziness, sudden death due to ventricular arrhythmia
- Findings: double apex beat, bisferiens pulse, S4, crescendo decrescendo murmur at base which becomes more prominent with valsalva or standing and less loud with squatting.
Sx of arterial insufficiency
- Pain – initially on activity and relieved by rest (intermittent claudication) due to muscle hypoxia
- Rest pain – progression of disease
- Paresthesia and numbness
- Cool or cold extremity
- Skin color changes – pallor (hypoxia),black means gangrene, red severe insufficiency
- Ulcers
Signs of arterial insufficiency
- Pallor
- Decrease skin temperature
- Loss of hair distally
- Loss of muscle mass
- Decrease to absent pulses
- Distal ulceration (tips of digit) • Peripheral neuropathy
- Gangrene
Special tests for arterial insufficiency
- Buerger’s test
- Allen’s test
Buerger’s test
- Raise both legs to 60 degrees, shoes off
- Patient wiggle feet and toes
- Hold for 60 seconds
- Have patient sit up and swing legs over the side of the bed
- Observe for return of color (10 seconds) and venous filling (15 seconds)
Signs of venous insufficiency (stasis dermatitis)
- Edema – dorsum of foot, posterior to medial
- malleolus, lower anterior leg
- Stasis dermatitis
- Ulcers – usually in the area of the medial
- malleolus
- Varicose veins
- Increase warmth due to associated cellulitis
- Cords – thrombosed superficial vein
Test for venous insufficency
- Manual compression test
- Trendelenberg’s test
Manual compression test
- Locate a portion of varicose greater saphenous vein in the leg or preferably bridging the thigh and leg
- Place the index and ring fingers (index finger on the inside) of both hands on the vein approximately 10 cm apart
- Compress with the proximal fingers to fill that portion of the vein with blood
- Compress with the distal fingers while maintaining pressure with the proximal fingers. A column of blood is now trapped.
- Lift the index finger of the distal hand (maintaining pressure with the other fingers) and tap over the vein. A fluid wave should be detected proximally.
- Replace the index finger applying pressure. Lift the index finger of the proximal hand and tap the vein. No fluid wave should be detected distally
Trendelenberg test: competency of valves of saphenous and communicating veins
- Test one leg at a time
- Raise leg to 90 degrees at the hip and maintain for I minute
- Apply tourniquet to upper thigh to occlude flow in the superficial veins
- Have patient stand on both legs
- Observe for rapid filling of the veins from below
- Wait for 20 seconds and remove tourniquet
- Observe for additional filling from above
Signs & sx of DVT
- Pain – usually of a dull ache that may be relieved by elevation of the leg
- Swellingand tightness of the leg
- Erythema
- Increased warmth of affected limb
Test for DVT
- Circumference of calf
- Homan
- Pratt

- Unregulated secretion of ADH
ASD
Left to right shunt, it might switch later forming Eisenmenger’s complex
i) Etiology: Usually congenital
ii) Results in:
(1) Right ventricular enlargement
(2) Pulmonary HTN
Signs:
- wide, fixed splitting
- Pulmonary flow murmur
- ECG show RBBB
VSD
Left to right shunt, it might switch later forming Eisenmenger’s complex
i) Etiology: Usually congenital small defect, If large
associated with growth retardation & CHF
ii) Results in:
(1) Right ventricular enlargement
(2) Pulmonary HTN
Signs:
- Loud pansystolic murmur -> Maladie de Roger
- Forceful apex beat with a thrill
- Mitral diastolic flow murmur
Tetralogy of fallot
Right to left shunt Results in:

(2) Increased feeding & crying
(3) Patient becomes apneic or unconscious
(4) Growth retardation
(5) Clubbing
(6) Polycythemia
Eisenmenger’s syndrome

Hypertrophic Cardiomyopathy (HCOM)
Obstructive
i) Etiology: 50% of cases autosomal dominant mutation
ii) Results in:
(1) Stiff ventricles impede diastolic filling
(2) Septal hypertrophy causing LV out flow tract obstruction

- Dyspnea on effort
- Syncope
- Sudden death in young adults
Congestive heart failure
Etiology: Multiple causes
(1) Pressure overload: LVH & then LVE
(2) V olume overload: L VH & L VE occur together
(3) Most common cause of RHF is LHF
ii) LHF results in:
(1) Hypotension -> BP could be normal due to
increased peripheral resistance
(2) Pulmonary edema -> SOB & Rales @ base of the lung
iii) RHF results in:
(1) ↑JVP, Pitting edema, ↑Liver congestion, ↓BP
Cardiac tamponade
Accumulation of fluid in pericardial space
i) Slow effusion results in:
(1) Right sided heart failure
(2) Severe pitting edema & ascites
(3) Pulsus paradoxus NOT as prominent
ii) Rapid effusion results in: MEDICAL emergency -> Patient is very ill
(1) ↑Peripheral resistance, Hypotensive, Chest x-ray shows enlarged heart
(2) Pulsus paradoxus
