1.Introduction
Chest pain is one of the most common complaints...
![Page 10: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/10.jpg)
One of the chief complaints in E.R• Chest Pain is the second most common presentation in
E.R visits, after abdominal pain.
• Can represent range of diseases from benign to life threatening.
• It is upto the clinician to exclude the life threatening causes first.

Triple Rule Out C.T Angiography• TRO-CTA provides a cost-effective evaluation of aorta,
coronaries, and pulmonary arteries in patients presenting with acute chest pain.
• Rules out three life threatening causes: 1 - Coronary Artery Disease 2 - Pulmonary Embolism 3 - Aortic Dissection +/- Cardiac Tamponade
• Can safely eliminate the need of further testing in 75% of the patients.

2.Cardiovascular
causes of Chest Pain
![Page 16: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/16.jpg)
Ischemic Heart Disease
• IHD must be excluded in all patients presenting with chest pain.
• Especially in middle and old age groups. Initial suspicion is on history.
• ECG may be normal in early stages of ACS, so a normal ECG doesn’t exclude ACS.
• Angina Pectoris is typical chest pain < 30 min (similar episodes in past)
- Seen in stable angina, coronary vasospasm
• Acute Coronary Syndrome (ACS) is typical / atypical chest pain > 30 min
- Seen in unstable angina (38%), NSTEMI (25%), STEMI (30%)
![Page 17: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/17.jpg)
Ischemic Heart Disease
• Unstable Angina (UA) - occurs at rest or with minimal exertion - it is severe and van be of new onset - it can occur with a crescendo pattern (distinctively more severe, prolonged, and frequent than previous episodes) - may or may not be relieved by rest or S/L nitrates - can precede myocardial infarction• Decubitus Angina
- Typical chest pain which appears after lying down - Due to increase in venous return and preload - Seen in heart failure and/or severe underlying CAD
![Page 18: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/18.jpg)

Classification Of Angina
Canadian Classification Scale (CCS) of AnginaClass I Angina on strenuous, rapid or prolonged exertion
No limitation of ordinary activity like walking or climbing stairs
Class II Slight limitation of ordinary activities like walking or climbing stairs, in cold, in wind, after meals, or emotional stress
Class III Marked limitation of ordinary activitiesi.e . after walking 1-2 blocks, or climbing 1-2 flight of stairs
Class IV Unable to perform any physical activity without discomfortAngina may be present at rest
![Page 21: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/21.jpg)

Medical Therapy in AnginaObjectives:• Prevent episodes of angina
Short-acting nitrates 5 min before planned exertion 1st line Anti-anginals - Beta Blockers and /or Calcium Channel Blockers 2nd line Anti-anginals - Long-acting nitrate, Ivabradin, Ranolazine, Nicorandil• Treat episodes of angina
During angina – Take a dose of short-acting nitrates If no relief after 5 min, repeat dose and call an ambulance• Secondary prevention of CV disease
- Lifestyle modifications - weight reduction, diet control, regular exercise - Anti-Platelet Therapy - Aspirin (+/- Clopidogrel) - Cholesterol lowering therapy - ideally with a statin (alt. is ezetimibe) - Treat hypertension if present - ideally with an ACEI or ARB - Refer to endocrinologist for diabetes management if present

Acute Pericarditis
• “Sharp” retrosternal chest pain• Aggravates on movement,
inspiration, cough and lying supine• Relieves on leaning forward• Signs: Tachycardia, pericardial
friction rub• There maybe history of recent MI
(Dressler’s syndrome)• ECG: diffuse ST elevation concave
upwards diffuse PR depression • Cardiac enzymes: may be
elevated

Acute Myocarditis
✘ “Sharp” retrosternal chest pain✘ Associated symptoms: palpitations, tachypnea✘ Sometimes concomitant with pericarditis, heart failure,
arrhythmias
✘ May preceded by pro-dromal symptoms like fever, rash, arthritis etc
✘ Seen with rheumatic fever, sarcoidosis, SLE or scleroderma
✘ Delayed complication = dilated CMP
✘ ECG – sinus tachycardia, QT prolongation, diffuse T wave inversions
✘ Increased troponin levels due to myocardial inflammation
![Page 26: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/26.jpg)
Aortic Stenosis
• Angina mimic – sub-endocardial ischemia due to raised LVEDP
• Syncope (LVOT obstruction & hypotension)• Features of heart failure may be present• Ejection Systolic Murmur at aortic area• Causes: aortic sclerosis (aging), RHD, congenital bicuspid
AV
• ECG – LVH, P. mitrale, possibly conduction blocks like LBBB
• Echo – dilated aortic root, thickened / immobile AV, concentric LVH,
On the basis of AVPG, AV area can be determined, AS can be graded as: Mild, Moderate, Severe, Very Severe

Hypertrophic CMP
• Typical chest pain (angina mimic) due to: increased demand (hypertrophy) reduced blood supply (aberrant coronary flow)• Syncope or pre-syncope (LVOT obstruction in 30% cases,
HOCM)• Features of heart failure may be present• Palpitations (if complicated by arrhythmias)• ECG – LVH, P mitrale, possibly PACs, PVCs, SVTs or a. fib
Septal hypertrophy – narrow “dagger like” Q waves in lat. & inf. leads Apical hypertrophy - giant inverted T waves in chest leads• Echo is diagnostic – Asymmetrical Septal Hypertrophy
(ASH)
![Page 30: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/30.jpg)

![Page 31: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/31.jpg)
Mitral Valve Prolapse
• Symptoms: atypical chest pain, panic, palpitations, pre-syncope, SOB
• Signs: Mid systolic click with a late systolic murmur Accentuated with standing and Valsalva maneuver• Significant MR can cause heart failure, and a holosystolic
murmur• Myxomatous degeneration of MV leaflets that bulge
backward into LA• Presents to us in second or third decade of life• ECG – may be normal, sinus tachycardia, LVH, P mitrale• Echo – concentric LVH, dilated LA, MR present
classic MVP - thickened mitral leaflets > 5mm - leaflet displacement > 2mm into LA during systole
![Page 32: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/32.jpg)
Mitral Valve Prolapse
![Page 33: Cardiology 1.1. Chest pain - by Dr. Farjad Ikram](https://reader035.fdocuments.in/reader035/viewer/2022062401/58ed325e1a28ab242a8b45cd/html5/thumbnails/33.jpg)
Cardiac Tamponade
• Symptoms: Atypical pain relieved by leaning forward, SOB, pre-syncope
• Signs: Beck’s triad (hypotension, engorged neck veins, muffled heart
sounds), pulsus paradoxus, pericardial rub, Ewart’s sign
• Fluid/blood in the pericardial sac resulting in the compression of heart
• Causes: trauma, heart rupture, aortic dissection, uremia, cancer, TB etc
• ECG – low voltage, tachycardia Electrical alternans – consecutive QRS complexes alternate in height, produced by heart swinging to and fro in a large fluid filled pericardium.• Echo is diagnostic. CXR is supportive. Cardiac markers may
be elevated.

Aortic Dissection
• Symptoms: Sudden onset of severe “tearing” pain in the inter-scapular
region of the back, sweating, vomiting and lightheadedness• If ascending aorta is involved - there can be frontal chest
pain, and cardiac tamponade can occur (most common cause of death in A.D)• MI can occur if aortic root is involved as coronary arteries
arise from it• Abdominal pain and GI bleed due to mesenteric ischemia• Syncope due to cerebral hypo-perfusion, paralysis due to
stroke• Tear inside the aorta causes the blood to between the
layers of the wall• Etiology: chronic hypertension causing cystic medial
degeneration• CXR – normal, wide mediastinum, wide aortic knob, left
pleural effusion• CT angiogram is diagnostic. MRI is the gold standard.
