πŸ«€ CARDIOVASCULAR SYSTEM β€” COMPLETE SUMMARY NOTES

(Ref: Merck Manual 20th Ed, Section 7)


TOPIC 1 β€” CARDIOVASCULAR TESTS & PROCEDURES

(Ch. 75)

⚑ ECG (Electrocardiography)

  • Records heart's electrical activity
  • P wave = atrial depolarization | QRS = ventricular depolarization | T wave = ventricular repolarization
ECG FindingThink of...
ST elevationSTEMI / Pericarditis
ST depressionNSTEMI / Ischemia
PR depressionPericarditis
Wide QRSBundle branch block
Electrical alternansCardiac Tamponade
Delta waveWPW syndrome
Deep Q waves (lateral)HCM (pseudo-infarct)

πŸ”Š Echocardiography

  • Ultrasound of heart - shows structure + function
  • TTE (transthoracic) = standard bedside
  • TEE (transesophageal) = better image; used for valves, aorta, thrombus
  • Tells you: EF, wall motion, valve function, pericardial effusion
Normal EF = 55-70% | EF <40% = HFrEF

πŸ”¬ Cardiac Catheterization

  • Catheter inserted via femoral/radial artery β†’ guided to heart
  • Left heart cath = coronary angiography (finds blockages)
  • Right heart cath (Swan-Ganz) = measures pulmonary pressures, cardiac output
  • Used pre-CABG, valve disease workup, chest pain evaluation

πŸƒ Stress Testing

  • Heart stressed via treadmill exercise or pharmacologic (dobutamine / adenosine)
  • Positive test = ST depression β‰₯1mm during exercise β†’ ischemia
  • Nuclear stress test = adds perfusion imaging (better sensitivity)

πŸ’‰ PCI (Percutaneous Coronary Intervention)

  • Balloon angioplasty + stent in blocked coronary artery
  • First-line for STEMI ("primary PCI within 90 min")

πŸ”ͺ CABG (Coronary Artery Bypass Grafting)

  • Surgical bypass using saphenous vein or internal mammary artery
  • For: multi-vessel disease, left main stenosis, failed PCI, diabetics

☒️ Radionuclide Imaging

  • Radioactive tracer (Tc-99m or Thallium) shows myocardial perfusion
  • Cold spot on stress only = reversible ischemia
  • Cold spot at rest + stress = fixed infarct (scar)

πŸ”„ Tilt Table Test

  • Patient tilted 60-80Β° upright; BP and HR monitored
  • Used for: unexplained recurrent syncope (reproduces vasovagal episodes)

TOPIC 2 β€” ARTERIOSCLEROSIS

(Ch. 77)
Arteriosclerosis = umbrella term for "hardening of arteries"

Four Types:

TypeVesselKey Feature
AtherosclerosisLarge/medium arteriesPlaque (lipid core + fibrous cap)
ArteriolosclerosisArteriolesHyaline or hyperplastic thickening; linked to HTN/DM
MΓΆnckeberg's SclerosisMedium muscular arteriesCalcification in media; lumen NOT affected
Fibromuscular HyperplasiaMedium arteriesIntimal SMC proliferation; post-injury or stents

Atherosclerosis β€” Pathogenesis

Endothelial injury β†’ inflammation β†’ plaque β†’ rupture β†’ thrombosis
  1. Endothelial injury (HTN, smoking, DM, high LDL)
  2. LDL enters intima β†’ gets oxidized
  3. Monocytes β†’ macrophages β†’ engulf ox-LDL β†’ foam cells
  4. Foam cells accumulate β†’ fatty streak (earliest lesion; reversible)
  5. SMCs migrate from media β†’ fibrous cap forms
  6. Atheromatous plaque = lipid core + fibrous cap
  7. Plaque rupture β†’ thrombus β†’ MI / stroke / sudden death
Atherosclerosis plaque showing fibrous cap over necrotic lipid core
A = vascular response to injury (SMC recruitment) | B = atheromatous plaque anatomy
Risk factors:
  • Modifiable: HTN, smoking, dyslipidemia, DM, obesity, sedentary lifestyle
  • Non-modifiable: Age, male sex, family history
Complications:
  • Stenosis β†’ Stable angina
  • Plaque rupture β†’ ACS (UA / NSTEMI / STEMI)
  • Carotid plaque β†’ Stroke
  • Weakened media β†’ Aneurysm

MΓΆnckeberg's Sclerosis (Non-Atheromatous)

  • Calcification of tunica media of muscular arteries
  • Lumen NOT affected β†’ usually clinically silent
  • Seen in diabetics, >50 yrs
  • X-ray: "pipe-stem" arteries | Mammogram: "railroad track" calcification
MΓΆnckeberg sclerosis histology - calcified media with intact lumen

TOPIC 3 β€” ENDOCARDITIS, MYOCARDITIS & PERICARDIAL DISEASES

(Ch. 82 & 86)

🦠 Infective Endocarditis (IE)

Common organisms:
OrganismContext
Strep viridansDental procedures, Sub-acute IE
Staph aureusIV drug users, prosthetic valves, Acute IE
EnterococcusGI/GU procedures
Strep bovisColon cancer (screen the gut!)
HACEK organismsCulture-negative IE
Clinical features:
  • Fever + new regurgitation murmur
  • Osler's nodes = painful nodules on fingers/toes
  • Janeway lesions = painless macules on palms/soles
  • Roth spots = retinal hemorrhages with pale center
  • Splinter hemorrhages under nails
  • Splenomegaly, embolic events (stroke, renal infarcts)
πŸ“Œ Memory: "From Jane's Roth Spot, Osler Splints"
Diagnosis: Blood cultures Γ—3 + Echocardiography (TEE preferred) Treatment: IV antibiotics 4-6 weeks; surgery if valve destruction or refractory

🚫 Non-Infective Endocarditis

TypeFeatureAssociation
Libman-SacksSterile vegetations on both sides of mitral valveSLE
NBTE (Marantic)Small thrombus on valve leafletsMalignancy, chronic illness
RheumaticAschoff bodies; later mitral stenosisGroup A Strep pharyngitis

❀️‍πŸ”₯ Myocarditis

  • Inflammation of the myocardium
  • Causes: Viral (Coxsackievirus B = most common in USA), autoimmune, drugs (doxorubicin), Chagas disease (Trypanosoma cruzi)
  • Features: Chest pain, fever, dyspnea, arrhythmias, sudden cardiac death
  • Diagnosis: Echo (wall motion abnormalities), cardiac MRI (gold standard), biopsy (Dallas criteria)
  • Risk: Can evolve into dilated cardiomyopathy
ECG in Myocarditis/Perimyocarditis:
ECG showing myocarditis with diffuse ST elevation across multiple leads
Diffuse ST elevation + tachycardia β€” seen in perimyocarditis

πŸ«€ Pericardial Diseases

Acute Pericarditis

  • Causes: Viral (most common), TB, post-MI (Dressler's), uremia, autoimmune
  • Pain: Sharp, pleuritic β€” worse lying flat, better leaning forward
  • Friction rub on auscultation (scratchy sound)
ECG β€” 4 Stages:
StageECG change
1Diffuse concave (saddle-shaped) ST elevation + PR depression
2ST returns to baseline
3T-wave inversion
4Normalization
πŸ”‘ Pericarditis vs STEMI: Pericarditis = diffuse + concave ST | STEMI = localized + convex ST
Treatment: NSAIDs + colchicine (first-line); steroids only if refractory

Pericardial Effusion

  • Fluid in pericardial sac (normally <50 mL)
  • Slowly accumulating β†’ can reach 2L (pericardium stretches)
  • Rapidly accumulating β†’ tamponade with even 200-300 mL

Cardiac Tamponade

  • Fluid compresses heart β†’ obstructive shock
  • Beck's Triad: Hypotension + Muffled heart sounds + JVD
  • ECG: Electrical alternans (QRS height alternates beat to beat)
  • Treatment: Pericardiocentesis (emergency needle drainage)

Constrictive Pericarditis

  • Fibrous scarring β†’ rigid shell around heart β†’ diastolic restriction
  • Causes: TB (most common globally), radiation, post-cardiac surgery
  • Features: JVD, Kussmaul's sign (JVP increases on inspiration), ascites, edema
  • Treatment: Pericardiectomy (surgical stripping)

TOPIC 4 β€” CARDIOMYOPATHY

(Ch. 79)
Three types of cardiomyopathy compared to normal heart
Dilated = big floppy | Hypertrophic = thick septum | Restrictive = stiff but normal size

Comparison Table:

FeatureDilatedHypertrophicRestrictive
ProblemSystolic (can't squeeze)Diastolic (can't relax)Diastolic (can't fill)
Wall thicknessThinThick (asymmetric septum)Normal or mildly thick
Chamber sizeAll 4 dilatedNormal/reduced LV cavityNormal
EF↓Normal or ↑Normal
Most common causeAlcohol / viral / geneticAutosomal dominant (sarcomere mutation)Amyloid / sarcoid
Classic patientMiddle-aged alcoholicYoung athlete with syncopeElderly with HF + low voltage ECG

1. Dilated Cardiomyopathy (DCM) β€” Most Common (90%)

  • All 4 chambers dilate β†’ thin walls β†’ systolic dysfunction
  • Causes (ABC):
    • Alcohol (most common toxin)
    • Babies (peripartum cardiomyopathy)
    • Coxsackie (post-myocarditis)
    • Drugs (doxorubicin, cocaine)
    • Encoded (genetic - titin mutations; AD in 50% of familial cases)
  • Signs: S3 gallop, pulmonary edema, mitral/tricuspid regurgitation (annular dilation)
  • Treatment: ACEi + beta-blocker + diuretics + ICD if EF <35%; heart transplant

2. Hypertrophic Cardiomyopathy (HCM)

  • Asymmetric septal hypertrophy β†’ LVOTO (outflow obstruction)
  • Genetics: Autosomal dominant; beta-myosin heavy chain mutation (most common)
  • Classic: Young athlete + syncope on exertion / sudden cardiac death
Murmur trick:
  • Increases with: Valsalva / standing (↓ preload β†’ worse obstruction)
  • Decreases with: Squatting / leg raise (↑ preload β†’ less obstruction)
  • (Opposite of most murmurs!)
ECG: LVH + deep narrow Q waves (lateral leads) β€” looks like MI but isn't
Treatment: Beta-blockers / verapamil; avoid nitrates + digoxin; ICD for high-risk; septal myomectomy or alcohol ablation

3. Restrictive Cardiomyopathy β€” Least Common

  • Stiff, non-compliant myocardium β†’ can't fill β†’ elevated filling pressures
  • Causes: Amyloidosis (apple-green birefringence on Congo red), sarcoidosis, hemochromatosis, radiation
  • ECG: Low voltage + conduction defects (amyloid deposits disrupt conduction)
  • Signs of both left and right HF; Kussmaul's sign may be present
  • Treatment: Treat underlying cause; supportive HF therapy

TOPIC 5 β€” SHOCK, DISEASES OF THE AORTA & ITS BRANCHES

(Ch. 74, 81; Sec. 6, Ch. 71, 72)

😡 Syncope

  • Transient LOC from cerebral hypoperfusion β†’ self-limiting, full recovery
TypeMechanismClue
VasovagalVagal surge β†’ bradycardia + vasodilationPain/emotion/prolonged standing trigger
OrthostaticBP drops on standingElderly, dehydration, antihypertensives
CardiacArrhythmia / structuralExertional syncope, sudden onset
Carotid sinusSinus hypersensitivityTight collar / head turning
⚠️ Syncope during exertion = CARDIAC until proven otherwise (think AS, HCM, arrhythmia)
Workup: ECG, Holter, Echo, Tilt table test, Carotid sinus massage

⚑ Shock

= Inadequate tissue perfusion β†’ cellular hypoxia β†’ organ failure
TypeCauseCOSVRCVP/PCWP
HypovolemicHemorrhage, dehydration↓↑↓
CardiogenicMI, severe HF, tamponade↓↑↑
Distributive (Septic)Sepsis, anaphylaxis↑ (early)↓↓
All shock: Hypotension + tachycardia + altered consciousness
  • Hypovolemic/cardiogenic: cold, clammy skin
  • Distributive (early septic): warm, flushed skin
Treatment:
  • Hypovolemic β†’ IV fluids / blood
  • Cardiogenic β†’ Dobutamine, norepinephrine, IABP, revascularize
  • Septic β†’ Fluids + broad-spectrum antibiotics within 1 hour + norepinephrine

πŸ”΅ Aortic Aneurysm

  • AAA (Abdominal): Dilation >3 cm, below renal arteries
    • Risk: Males >65, smokers, HTN, atherosclerosis
    • Screening: Abdominal USS in males >65 who ever smoked
    • Repair: >5.5 cm, or rapid growth >1 cm/yr, or symptomatic
  • TAA (Thoracic): Associated with Marfan's, bicuspid aortic valve, syphilis

πŸ”₯ Aortic Dissection

  • Intimal tear β†’ blood enters media β†’ false lumen
  • Pain: Sudden, severe, tearing chest-to-back pain β€” max intensity at onset
  • Signs: Unequal BP in both arms, pulse deficit, aortic regurgitation murmur
Stanford Classification:
TypeWhereTreatment

🌊 Takayasu's Arteritis (Aortic Arch Syndrome)

  • Granulomatous vasculitis of the aorta and major branches
  • Who: Young women <40; Asian populations
  • Nickname: "Pulseless disease"
Two phases:
  1. Inflammatory: Fever, fatigue, myalgia, ↑ESR/CRP
  2. Fibrotic/Occlusive: Absent radial pulses, BP difference between arms, bruits, limb claudication, renovascular HTN
Diagnosis: MR angiography; biopsy if accessible vessel Treatment: Corticosteroids first line; methotrexate / tocilizumab for refractory; angioplasty / bypass for occlusion

Aortic bifurcation (Iliac)Leriche SyndromeButtock claudication + erectile dysfunction + absent femoral pulses

TOPIC 6 β€” PERIPHERAL ARTERIAL DISORDERS

(Ch. 87)

🦡 Peripheral Arterial Disease (PAD)

  • Atherosclerosis of limb arteries (mostly lower limb)
Stages of severity:
StageSymptom
AsymptomaticNo symptoms
Intermittent claudicationCalf pain on walking β†’ relief with rest
Rest painFoot pain at night; relieved by dangling leg
Critical limb ischemiaUlcers / gangrene
Signs: Cool pale limb, absent pulses, hair loss on legs, non-healing ulcers at toes
Key Diagnostic Test β€” ABI (Ankle-Brachial Index):
ABI ValueInterpretation
>0.9Normal
0.7-0.9Mild PAD
0.4-0.7Moderate PAD
<0.4Severe / Critical ischemia
>1.3Non-compressible vessels (calcification)
Ankle-Brachial Index test method for diagnosing PAD
ABI = ankle systolic BP Γ· arm systolic BP
Treatment:
  • Stop smoking (most important)
  • Antiplatelet: aspirin or clopidogrel
  • Statins (stabilize plaque)
  • Cilostazol (improves claudication)
  • Revascularization: Angioplasty / bypass for critical ischemia

❄️ Raynaud's Syndrome

  • Episodic digital vasospasm from cold or stress
  • Color sequence: White β†’ Blue β†’ Red
    • White = ischemia (vasospasm)
    • Blue = cyanosis (stagnant blood)
    • Red = reactive hyperemia (reperfusion)
TypeFeature
Primary (Raynaud's disease)Young women; no underlying disease; benign
Secondary (Raynaud's phenomenon)Associated with scleroderma (most common), SLE, drugs (beta-blockers)
Treatment: Avoid cold; calcium channel blockers (nifedipine); sympathectomy if severe

πŸ”₯ Thromboangiitis Obliterans (Buerger's Disease)

  • Segmental inflammatory thrombosis of small/medium arteries AND veins
  • Classic patient: Young male, heavy smoker
  • Affects fingers, toes, hands, feet β†’ ulcers, gangrene
  • No atherosclerosis but strongly linked to tobacco
  • Hallmark: Migratory superficial thrombophlebitis
  • Only effective treatment: Absolute smoking cessation
  • Other: Prostaglandins (iloprost), amputation if needed

πŸ’œ Acrocyanosis

  • Persistent, painless, bluish discoloration of hands and feet
  • Benign vasospasm of cutaneous arterioles
  • Worsens with cold; improves with warmth
  • No tissue ischemia, no ulcers, no episodic attacks
  • Distinguished from Raynaud: persistent (not episodic) + painless

πŸ”΄ Erythromelalgia

  • Opposite of Raynaud: Burning, red, hot extremities
  • Triggered by warmth; relieved by cold water immersion
  • Associated with polycythemia vera and myeloproliferative disorders
  • Treatment: Aspirin (especially if polycythemia vera); avoid heat

🩸 Fibromuscular Dysplasia (FMD)

  • Non-inflammatory, non-atherosclerotic disease of medium arteries
  • Affects: Renal arteries β†’ renovascular HTN | Carotid arteries β†’ stroke/TIA in young women
  • Angiography: Classic "string of beads" appearance

TOPIC 7 β€” PERIPHERAL VENOUS & LYMPHATIC DISORDERS

(Ch. 88)

🩸 Deep Venous Thrombosis (DVT)

Virchow's Triad (risk factors):
FactorExamples
StasisImmobility, long flights, pregnancy, post-op
HypercoagulabilityOCP, malignancy, Factor V Leiden, antiphospholipid syndrome
Endothelial injurySurgery, trauma, IV cannula
Symptoms: Unilateral leg swelling + pain + warmth + redness
Diagnosis:
  • D-dimer β†’ highly sensitive; negative D-dimer rules OUT DVT
  • Compression ultrasound β†’ gold standard; non-compressible vein = DVT
DVT ultrasound showing non-compressible common femoral vein
Left: Vein does NOT compress (DVT present) | Right: Normal vein collapses with probe pressure
Complication β€” Pulmonary Embolism (PE):
  • Clot travels to pulmonary artery β†’ dyspnea, pleuritic chest pain, hypoxia, tachycardia
  • Massive PE β†’ obstructive shock + RV strain on ECG (S1Q3T3)
  • Treatment: Systemic thrombolysis (tPA) for massive PE; anticoagulation for submassive/non-massive
DVT Treatment:
  • DOACs (rivaroxaban, apixaban) = first line
  • LMWH in cancer-associated DVT
  • Warfarin (INR 2-3) if DOACs unavailable
  • Duration: 3-6 months provoked; β‰₯12 months or lifelong unprovoked/recurrent
  • IVC filter if anticoagulation is contraindicated

πŸ”΄ Superficial Venous Thrombosis (SVT)

  • Clot in superficial veins; visible, tender, cord-like
  • Usually in varicose veins or around IV cannulas
  • Less dangerous than DVT; can extend to DVT especially near saphenofemoral junction
  • Treatment: NSAIDs, compression; fondaparinux if high risk of DVT extension

πŸŒ€ Varicose Veins

  • Dilated, tortuous superficial veins from incompetent venous valves
  • More common: Women, pregnancy, prolonged standing
  • Symptoms: Aching, heaviness, visible bulging, ankle swelling
  • Complications: Lipodermatosclerosis, venous eczema, venous ulcers (medial ankle)
  • Treatment: Compression stockings; sclerotherapy; laser/radiofrequency ablation; vein stripping

🦡 Chronic Venous Insufficiency & Post-Phlebitic Syndrome

  • Long-term venous hypertension + valve damage (often after DVT)
  • Features: Edema, hemosiderin pigmentation (brown skin), lipodermatosclerosis, venous ulcers
Venous Ulcer vs Arterial Ulcer β€” Key Differences:
FeatureVenous UlcerArterial Ulcer
LocationMedial ankle (gaiter area)Toes / pressure points
AppearanceShallow, irregular, wetDeep, punched-out, dry
PainRelatively painlessVery painful
PulsesPresentAbsent
Surrounding skinPigmented, induratedPale, atrophic, hairless
ABI>0.9<0.9

πŸ’§ Lymphedema

  • Impaired lymphatic drainage β†’ protein-rich fluid accumulates β†’ non-pitting edema
TypeCause
PrimaryCongenital (Milroy's disease) or idiopathic
SecondaryBreast cancer surgery/radiation (most common in developed world), filariasis (Wuchereria bancrofti - globally)
Features:
  • Starts pitting β†’ becomes non-pitting over time
  • Skin thickens (peau d'orange texture)
  • Stemmer's sign = cannot pinch skin at base of 2nd toe
  • Complications: Recurrent cellulitis, lymphangiosarcoma (Stewart-Treves syndrome)
Treatment: Complex decongestive physiotherapy (CDT) + compression garments + pneumatic compression (no cure)

πŸ”΅ Idiopathic Telangiectasia (Spider Veins)

  • Dilated superficial capillaries/venules
  • Usually cosmetic; may be hereditary (HHT = Osler-Weber-Rendu)
  • HHT features: Epistaxis + GI bleeding + pulmonary AVM
  • Treatment of spider veins: Sclerotherapy or laser

πŸ” Arteriovenous Fistula (AVF)

  • Abnormal connection between artery and vein (bypasses capillary bed)
  • Congenital or acquired (trauma; dialysis access is deliberately created)
  • Features: Continuous machine-like murmur over site; distal ischemia ("steal"); high-output cardiac failure if large
  • Treatment: Surgical ligation or endovascular embolization (except dialysis AVF)
