•
Our Topic is limited to PHC level, therefore the approach to Chest Pain and the Management
of the conditions is based on PHC management guidelines up to the point of referral to
hospital.
•
Some hospital level resources and material were consulted in order to expand on the topic for
learning purposes.
•
Chest Pain as a clinical presentation at PHC was a broader topic, so we focused more on the
Life Threatening causes and put more focus on Myocardial Infarction because of its importance
in the clinical setting...
Definition of Chest Pain
•
A discomfort in the chest/ thorax including a dull ache, a crushing/ burning feeling/ a
sharp stabbing pain
•
It can radiate to the neck, jaw arm/ back;
•
It can be cardiac or non cardiac;
•
According to the underlying cause; and these range from immediately life threatening
to the trivial.
•
Chest pain is a common presentation on the CHC and it’s important as a health
professional to be able to exclude the life threatening causes.
Approach to Chest Pain at a PHC level
Cardiac & Non Cardiac Causes
•
Cardiac: (Acute Myocardial Infarction, Angina Pectoris)
•
Non Cardiac: (Dissecting Aortic Aneurysm, Massive Pulmonary Embolus, Tension
Pneumothorax, Esophageal Rupture, Esophageal reflux, Peptic Ulcer Disease,
Pericarditis, Pneumonia, Musculoskeletal Disease- Costocondritis, Emotional and
Psychiatric Conditions)
Recognize the patient with Chest Pain needing
urgent attention
5 Life Threatening Causes of Chest Pain
•
Myocardial Infarction
•
Dissecting Aortic Aneurysm
•
Massive Pulmonary Embolus
•
Tension Pneumothorax
•
Esophageal Rupture
Clinical Approach
Patient History OPQRST
•
Onset: What was the patient doing when the pain started
•
Provocation: What makes it better or worse?
•
Quality: Can you describe it? How does it feel like?
•
Radiation: Where do you feel the pain, where else does the pain go?
•
Severity: How bad is the pain on a scale of 1-10?
•
Time: When did the pain start?
•
Vitals:
•
BP: >/=180/110 Or BP: <90/60
•
Pulse: Irregular, >100 or <60
•
Symptoms
•
Severe Chest Pain
•
New onset of central chest pain
•
Pain Spreads to the Neck, Arm or Back
•
Sweating, nausea & Vomiting
•
General Exam
: Pale
•
Patient History:
DM, Smoker, HPT, Known CVD risk>10%, Known with Ischemic Heart
Disease/ immediate family history.
•
Provisional
Dx: ACS (MI/ Angina)
Management Route
•
If conscious, sit patient up
•
Give 40% face mask oxygen
•
If BP< 90/60, give 200ml Sodium Chloride 0.9% IV
•
Further Manage according to Temperature
•
>/= 38 degrees C, Chest infection likely
•
< 38 d greed C, Do an ECG
•
If ECG is normal/ unavailable/ uncertain: Is Chest Pain worse on lying down/ palpating/ breathing
deeply?
•
If yes to any of the above, Heart attack unlikely, Refer urgently
•
If No to the above question, Heart attack likely- Refer to ACS Management
•
ECG abnormal- Refer to ACS management
CONTIGUOUS?
Acute Coronary Syndrome
•
Most important due to commonality as well as lethality
•
It’s a top differential, first enquirer
•
Includes a range of conditions from Angina to Acute Myocardial Infarction, which vary
from patient to Patient, caused by acute myocardial ischaemia
•
1. Stable Angina
•
2. Unstable Angina
•
3. NSTEMI
Acute Myocardial Infarction
•
Onset at Rest, subacute onset (minutes)
•
Severe central chest pain
•
Sweating
•
Anxiety
•
Associated Symptoms ( Nausea & Vomiting)
•
No relief with Nitrates
Physiopathology
•
The Chest Pain of Angina and myocardial infarction are due to the accumulation of
metabolites from ischemic muscle following complete or partial obstruction of a
coronary artery which leads to stimulation of cardiac sympathetic nerves
Risk Factors
•
Modifiable
•
Obesity
•
Smoking: Significant Smoking History recorded as packet years: The risk of IHD falls gradually over the
years after smoking has been stopped.
•
Diet
•
Sedentary Lifestyle
•
High Serum Cholesterol (Hypercholesterolemia): Total serum cholesterol of > 5.2 mmol / L is undesirable
•
Hyperlipidemia: High alcohol consumption and obesity are associated with hyper triglyceride is
•
Non Modifiable
•
Cardiac Transplants: Patients with cardiac transplants may not feel angina, presumably because the heart
is denervated
•
Diabetes: Patients with diabetes are likely to be diagnosed with “silent infarcts”
•
Hypertension: Risk for coronary artery disease especially if no treatment has been instituted
Non modifiable Risk Factors continued...
•
Previous Coronary Disease
•
Family History of Coronary Artery Disease: 1st degree relatives- parents and siblings
•
Chronic Kidney Disease: Related to high calcium-x-phosphate product, needs dietary
intervention, phosphate binders, efficient dialysis or renal transplant
•
Chronic Inflammatory Rheumatological Disease- Rheumatoid Arthritis
•
Erectile Dysfunction: Sensitive Indicator of arterial endothelial abnormality
•
Dental Caries: Associated with an increased risk of ischemic heart disease
•
Male sex and advanced age
Risk Stratify the patient
TIMI Risk Score
•
Age > 65
•
>3 Coronary artery Factors
•
Known coronary artery stenosis
•
Use of Aspirin in the last 7 days
•
Elevated cardiac bio markers
•
Severe Angina (>2 episodes in <24 hours)
•
ST depression or elevation> 0.5mm
•
(0-2= low risk; 3-4= medium risk; 5-7= high risk)
Management
ACLS Principles
Adjuncts
Aspirin
Adjuncts
•
300mg chewed po stat
•
C/I: Known Hypersensitivity
•
Relative C/I: Active PUD; Bleeding Disorder
•
MOA: Non selective COX inhibitor; decreases Thromboxane A2 production by platelets
(responsible for platelet aggregation)
Clopidogrel
•
600mg for both STEMI & NSTEMI ( faster onset of action with higher loading doses,
with no increase in S/E
•
MOA: Antiplatelet agent by inhibiting ADP binding to platelet and subsequent activation
of GPIIb / IIIa receptor complex
Enoxaparin
•
30mg IVI stat
•
Then 1mg/kg s/c 15 later
•
MOA: LMWH binds with AT III to form complex inhibits factor Xa and therefore
conversion prothrombin - thrombin
Nitroglycerin
•
Nitrous Oxide Donor, Vasodilation
•
0.5mg S/L every 5 minutes ( max 3 doses)
•
C/I: Hypotention (SBP<90mmHg) ; Severe Bradycardia (HR<50BPM); Severe
Tachycardia ( HR> 100BPM); RV infarction (inferior MI); Use on PDE- I
Simvastatin
•
40mg po stat
•
MOA: anti inflammatory effect with plaque stabilization
•
Other
Medication
•
Morphine for pain
•
Beta Blockers if not contraindicated
The other 4 Life Threatening Causes of Chest
Pain
Dissecting Aortic Aneurysm
•
Instantaneous onset
•
Radiates to back
•
Very severe pain,
•
Tearing quality
•
Anterior Chest Pain: Proximal Dissection
•
Inter scapular pain: Descending Aorta
•
RF: HPT/Connective Tissue Disorders- Marian’s Syndrome & Ehler’s- Danlos syndrome
•
Management: Stabilize Patient, Refer to Hospital for Further Management
Massive Pulmonary Embolism
•
PE often occurs without symptoms or signs
•
Sudden and unexplained dyspnoea
•
Pleuritic Chest Pain and Hemoptysis occurs only when there is Infarction
•
Syncope or the sudden onset of severe substernal pain usually occurs with
Massive
Embolism
Risk Factors
•
Previous PE
•
Immobilization ( Long aeroplane or car trip/ post surgical intervention especially lower
limb orthopedic operations)
•
Known clotting- factor abnormalities
•
Known Malignancy
Signs
•
PE
•
General Signs: Tachycardia, tachypnoea, fever (with Infarction)
•
Lungs: Pleural Friction rub if Infarction has occurred
•
Massive Embolism
•
Elevated JVP
•
Right Ventricular Gallop
•
Right Ventricular Heave
•
Tricuspid Regurgitation Murmur,
•
Palpable Pulmonary component of the second heart sound (P2)
•
Gallop (S3 &/ S4)
Wells’s Probability Score
•
Clinical signs and symptoms of DVT (minimum of leg swelling and pain with palpating of the deep veins)= 3.0
•
An alternate diagnosis is less likely than PE= 3.0
•
Heart Rate > 100 bpm= 1.5
•
Immobilization at least 3 days, or surgery in previous 4 weeks= 1.5
•
Previous PE/DVT= 1.5
•
Haemoptysis= 1.0

•
Interpretation:
•
Low probability: <2.0
•
Moderate probability: 2.0-6.0
•
High Probability: >6.0
•
Can use PERC.
Management
•
Protect Airway
•
Supply oxygen
•
Ensure adequate ventilation,
•
IV Access and Fluid boluses
•
Refer to Hospital
•
Low Risk PE: Passive anti- coagulation with Warfarin until INR (2-3)
•
Massive PE:
•
Inotropic Support
•
Thrombolysis if not contraindicated
Tension Pneumothorax
•
It’s a medical emergency
•
This occurs when there’s communication between the lung and the pleural space with a
flap of tissues acting as a valve, allowing air to enter the pleural space during
inspiration and preventing it from leaving during expiration.
•
It results from air accumulating under increasing pressure in the pleural space
•
It causes displacement of the mediastinum with obstruction and kinking of the great
vessels
Signs
•
Injuries
•
Tachypnoeic and cyanosis; May be Hypotensive
•
Trachea and Apex beat displaced away from the affected side
•
Expansion reduced or absent on the affected side
•
Hyper-resonant over the affected side
•

Insert a wide bore IV cannula through the 4th and 5th intercostal space in the anterior
ancillary line on the affected side, withdraw the needle and retain the cannula and
Refer the patient with until until the hospital where an urgent intercostal drain can be
inserted
•
Cover penetrating wounds on the chest with sterile dressing, tape 3 sides of the
dressing and leave 1 side untapped.
Esophageal Rupture
•
Are tears that penetrate the wall of the esophagus
•
Rare
•
Ruptures can be caused by surgical procedures, severe vomiting, or swallowing large piece of food, some
spontaneous

Prolonged
•
Localised
•
Management
: Analgesia and anti- inflammatory (Panado 1g po tds and ibuprofen 400mg po

Conclusion
•
Chest Pain at PHC is a common presentation
•
It’s important to recognize patients who need urgent medical attention
•
Acute Coronary Syndromes-AMI is top priority of the 5 Life Threatening causes of Chest Pain due
to its commonality and lethality
•
Following the Right Approach to Chest Pain at the PHC level will help us not miss the Golden time
for the prompt management of medical emergencies of Chest Pain
•
For proper management of patients it’s important to follow the Management guidelines of both
Life Threatening and Non Life Threatening causes of Chest pain
•
Remember always that Epigastric Pain/ discomfort is not always Gastritis, it could be a sign for a
Medical Emergency, an AMI.
Recommendations
•
The mention of Chest Pain by a patient should provoke more urgent attention than
other symptoms, the attending phc doctor should have a high index of suspicion for the
5 life threatening causes of Chest Pain and first exclude a Myocardial Infarction.
•
The attending phc doctor should be familiar with how both cardiac and non cardiac
causes of chest pain present and be competent in clinically diagnosing these, revisit
Talley & O’Conner.
•
PHC doctors should prioritize chest pain presentations at ED and approach atypical
chest pain with caution.
•
Remember Always that Epigastric Pain is not always Gastritis/ PUD
