Q

Principle regarding heart murmurs

A

All will get worse / more prominent with more volume in the heart, however,
MVP and HOCM are the odd ones out; they’ll get worse with less volume in the heart.

Maneuvers that decrease blood in the heart

A

Valsalva; standing up from seated position; sitting up from supine position;
administration of nitrates any of these will cause MVP + HOCM to get worse;
all other murmurs will soften or not change.

Caused by pancoast tumor (Adenocarcinoma of Lungs)

23
Q

Lyme Disease

A

Caused by Borrelia Burgdorferi, a spirochete transmitted by Ixodes tick in Northeast, Mid west, and West coast.

Erythema Migrans (Target shaped lesion ; Bulls Eye lesion) is first symptom.

After several weeks of dissemination;
- Neurological Symptoms: Cranial Nerve Palsy , Bells Palsy.
- Heart block (AV block).
- Arthritis (follows after months to years) due to immune complex type III hypersenstivity.

Tx: Doxycycline.

24
Q

Cardiac Murmurs concept

A

Flow through the effected valve:

  • ↑Blood Flow = ↑Intensity of Murmur.
  • ↓ Blood flow = ↓ Intensity of Murmur.

Preload & Afterload can be changed by manuevers and can affect the murmurs:

  • Inspiration & Rapid squatting >↑ intra thoracic pressure > ↑Venous return > ↑ Preload >↑Right sided murmur.
  • Handgrip, Valsalva ↑ Afterload > ↓Intensity of the murmur ( VSD, MR, AR ).
25
Cardiac Action potential
26
Wolf-Parkinson-White syndrome (WPW-Syndrome)
- Due to presence of accessory pathway conduction (bundle of kent). - Shortened PR-interval, Widened QRS complex. - Delta wave. - Most common type of ventricular pre-excitation syndrome. - No AV nodal delay for diastolic filling.
27
1st Degree Heart Block
- Benign & Asymptomatic - Increase PR-interval (>200msec)
28
2nd Degree Heart Block (Type-I)
Mobitz type-I (Wenckebach) : - Gradual prolongation of PR-interval until u get a P-wave which is not followed by QRS complex (Dropped beat).
29
2nd Degree Heart Block (Type-II)
Mobitz type-II : - No prolongation of PR-interval - Beat is dropped - Problem in Bundle of His (fibrotic changes) - Tx: Pacemaker
30
3rd Degree Heart Block (Complete AV-block)
- Complete dissosiation of Atria & Ventricles. - No synchronization between atria & ventricles. - Ventricles are responding to Ectopic beats. - Atria and Ventricles depolarize together and create P-wave on QRS or P-wave on T-wave. - One of the HY cause of 3rd degree block is Lyme disease caused by Borriela Burdogferi.
31
Chagas Disease
Caused by Protozoa Trypanasoma Cruzii endemic to south america with reduvid bug (Kissing bug) as vector, it can also be transmitted person to person. - Preferentially infects heart and myenteric nerves. Causing: > Dilated Cardiomyopathy > Heart failure > Arrhythmias Also assocaited with: > Myocarditis > Megaesophagus with achalasia > Megacolon Its one of the bugs that can cause heart block.
32
Give the classic tetrad of IgA vasculitis (Henoch-Schonlein purpura).
1. Palpable purpura without thrombocytopenia or coagulopathy (typically over the posterior lower extremities and buttocks) 2. Arthritis/arthralgia 3. Abdominal pain (due to localized bowel wall inflammation; patients are at risk of intussusception) 4. Kidney disease (hematuria +/- proteinuria)
33
A young adult who smokes and has painful ulcers with dry gangrene on the toes but normal pulses in the foot most likely has?
Buerger disease (thromboangiitis obliterans). Histopathology reveals segmental inflammatory intramural thrombi of medium and small vessels
34
A 55-year-old woman presents with unilateral headache, transient vision loss, and jaw claudication. What is the diagnosis?
Giant cell arteritis. The screening test for this condition is (erythrocyte sedimentation rate [ESR]). A (temporal artery biopsy) is typically obtained to confirm the diagnosis.
35
Eosinophilic granulomatosis with polyangiitis AKA Churg Strauss
1. Asthma (Late Onset), sinusitis 2. Peripheral neuropathy (mononeuropathy multiplex , Wrist drop) 3. Subcutaneous nodules or purpura 4. Eosinophilia 5. Antibodies against Neutrophil MPO (p-ANCA Pattern) The heart, gastrointestinal system, and kidneys can also be involved. IgE levels are elevated.
36
Cardiac Action potential
37
Granulomatous with Polyangitis (GPA)
Systemic necrotizing granulomatous vasculitis affected small and medium vessels. Assosiated with c-ANCA (cytoplasmic anti neutrophil cytoplasmic antibody). GPA most commonly infects Sinopulmonary tract, Kidneys and Skin. Can present as: Sinusitis, Otitis Media, Mastoditis, Nasal ulceration w Epitaxis, Hemoptysis, Cough. Hematuria increase risk of RPGN and Renal failure. Fever, Wt.loss and fatigue are constitutional symptoms.
38
Dressler syndrome
Chest pain, pericardial effusion/friction rub, persistent fever following MI (autoimmune-mediated post-MI fibrinous pericarditis, 2 weeks to several months after acute episode)
39
Pulmonary HTN
- Progressive Dyspnea - Loud Pulmonic Component of S2 (Left upper sternal border) - Hereditary form of Pulmonary atrial HTN (PAH) is due to AD inactivating mutation of BMPR2 gene, predisposing the patient to excessive endothelial injury & smooth muscle proliferation.
40
Infective Endocarditis
Pneumonic "FROM JANE" - F = Fever - R = Roth Spot - O = Osler Nodes - M = Murmur - J = Janeway Lesions - A = Anemia - N = Nail bed hemorrhage (Splinter hemorrhage) - E = Emboli - Digital Clubbing may also be seen
41
Left Heart Failure (LHF)
- Presents as pulmonary findings (i.e., pulmonary edema, dyspnea, orthopnea, paroxysmal nocturnal dyspnea). - If there is left heart pathology, PCWP is high - Hx of Long standing uncontrolled HTN - Dyspnea - Orthopnea - Pulmonary Crackles LHF → ↑ Diastolic filling pressure → Pulmonary HTN → Rt. Heart Failure
42
Right Heart Failure (RHF)
- Presents as systemic findings – i.e., jugular venous distension (JVD) & peripheral edema - Hx of Pulmonary HTN - Jugular Venous distention - Pulmonary Edema
43
Congestive Heart Failure (CHF)
- Congestive heart failure = left heart failure + right heart failure. - The most common cause of right heart failure is left heart failure. - In congestive heart failure, we’ll see both left- and right-heart failure findings – i.e., patient will have dyspnea, JVD, and peripheral edema. - PCWP is elevated in these patients, since the left heart has pathology.
44
Cor Pulmonale
- Cor pulmonale is defined as right-heart failure due to a pulmonary cause. - Cor pulmonale will be a patient who has JVD and peripheral edema in the setting of obvious and overt lung disease - A loud P2 and tricuspid regurgitation are HY findings in cor pulmonale.
45
Atrial Septal Defect (ASD)
- Fixed splitting of S2 - ASDs can sometimes be responsible for “paradoxical emboli,” where a DVT leads to stroke.
46
Granulomatosis with polyangiitis
- AKA Wegener granulomatosis. - Triad of: 1) Hematuria, 2) Hemoptysis, 3) “Head-itis” – i.e., any problem with the head, such as nasal septal perforation, mastoiditis, sinusitis, otitis. - Associated with cANCA and anti-proteinase3 (anti-PR3) antibodies
47
Eosinophilic granulomatosis with polyangiitis
- AKA Churg Strauss - Presents as combo of asthma + eosinophilia +/- head-itis. - Associated with pANCA and anti-myeloperoxidase (anti-MPO) antibodies.
48
Microscopic polyangiitis
- Will just present as hematuria in a patient who is pANCA / anti-MPO (+). - Similar to Wegener, can cause RPGN.
49
Hyperchylomicronemia (AR)
Deficiency of lipoprotein lipase or Apolipoprotein C-II - Increase Chylomicrons + TGAs. - Pancreatitis (abdo, not chest, pain). - Xanthomas. - Plasma appears “creamy
50
Hypercholesterolemia (AD)
Deficiency (heterozygous) or absence (homozygous) of LDL receptor or Apo B-100 - Increase LDL. - LDL usually 700-1000 in homozygotes, with MI in teens (answer = absence of functional LDL receptor). - Xanthomas
51
Hypertriglyceridemia (AD)
Increase Hepatic production of VLDL - Increase TGAs. - Pancreatitis.
