Pre-hospital management of Cardiovascular disorders in
our perspective
Prof A.K.M. Rafique uddin Professor and Head
Department of Medicine Enam Medical College and Hospital
Our perspective
• Population density : 964/km2
• M:F – 100.3: 100
• Population 14 crore 79 lac (2010 – 2011)
• Current national population growth 1.35%
• Hospital bed 1 for 1860
• Registered doctors - 1 for 2785
• Per capita income – 818 US dollar
• Per head GDP – 692 US dollar
Our perspective Continued..
The proposed Tk 8889 crore in national health
budget 2011 is too little for over 150 million of people.
The per capita allocation in healthcare is Tk 590 or
$7.5 per year per person.
In USA, health budget is 8,047 US dollar per person
& In UK, 3713 US dollar per capita per year.
Our perspective Continued..
• The media of education is English.
• Their education and management level is much advanced which is beyond the reach of our poor people.
• Our doctors are even unable to understand many of the symptoms which are expressed in colloquial language .
Cont.
• The majority of deaths from coronary disease occur in the pre-hospital phase and most victims do not get any medical support.
Cont.
• In the western countries every citizen is trained with Basic Life Support(BLS)
• But in Bangladesh , even the graduate physicians are not well trained with this BLS.

Presentation of CV Disorders Continued..
Sudden cardiac Death
• Sudden and complete loss of cardiac function in apparently healthy person.
• Diagnosed by- Loss of consciousness Cessation of respiration Absence of pulse
Management
• Should be started very promptly within minutes. If delayed by more than 3 minutes, there will be permanent brain damage.
In abroad
In Bangladesh
Pre-hospital Management
• Precordial Thump
• A- Airway clearance
• B- Breathing
• C- Cardiac message
• D- Drip, Drug and Defibrillation
Cardio-pulmonary Resuscitation………Continue
Acute Chest Pain (Angina/MI/Angina equivalent)
Chest pain or discomfort in or around the chest due to myocardial hypoxia secondary to inadequate coronary blood flow which usually aggravates by exercise and relieved by rest or GTN.
Diagnosis
• Any symptoms over chest, neck or upper abdomen
• Nausea, vomiting related with exertion
• Features of sympathetic over-activity e.g sweating, palpitation and breathlessness
• Features persisting more than 20 minutes considered as serious cardiac damage i.e MI
Drugs
Sublingual nitroglycerine
Aspirin
Iso-sorbide mono and di-nitrate
Negative inotropic drugs e.g beta –blockers ,calcium channel blockers
• After amelioration of the symptoms patient should be transferred to hospital for further evaluation and management.
Myocardial Infarction
• Absolute bed rest
• High flow oxygen ?
• Analgesic e.g. pethedine (should be avoided)
• Thrombolytic agents if the patient encounters within 6 hrs
Continued..
Continued..
• Aspirin
• Coronary vasodilators
• IV channels
• Treatment of complications
Syncopal attack
Transient loss of consciousness due to inadequate cerebral blood flow.
D/D
• True Syncope
• Hysterical Conversion Reaction
• Malingering
Pre-hospital management
• Lying down the patient with raising the foot-end
• Majority patients specially younger and in situational syncope , do not require any evaluation.
• For other patients, specially elderly and recurrent attack further evaluation should be done and referred to specialized centre for better management.
Shock(Acute Circulatory Failure)
Inadequate tissue perfusion due to disproportional distribution of circulatory volume and circulatory bed characterized by restlessness, confusional state, profused sweating ,low thready rapid pulse and unrecordable BP.
Pre hospital Management
• If hypovolaemic- fluid is mandatory
• JVP should be the guideline
– If supraclavicular fossa full
– then possibility of cardiogenic shock
• Give pressure amine
• Transfer to hospital in a proper way.
Cont.
• Treatment of underlying causes e.g. control of haemorrhage, control of infection by antibiotics
• Treatment of complications
Renal failure
Dyspnoea
• One of the principal presentation of Left Ventricular failure , acute pulmonary edema and ARDS.
• Diagnosed by Short history Known cardiovascular disorders e.g. Myocardial infarction , Hypertension, Valvular
disease
DIAGNOSIS
Pulsus alternans or arrhythmias
BP - hypertension
Shifting of apex beat
Bilateral basal crepitation
Gallop rhythm
Cardiac murmurs
Management
• Propped up posture
• O2 inhalation !
• Sedation
• Diuretics - frusemide
• Salbutamol inhaler or nebuliser if associated brochospasm
• Vasodilators
• Beta blockers
• Digoxin …?
After amelioration of the symptoms patient should be transferred to hospital for further evaluation and management.
Passive venous congestion(CCF)
• Oedema
• Ascites
• Hepatomegaly
Diagnosed by History of-
• Known cardiovascular disorders
• Breathing difficulties prior to presenting features
Signs
• Dependent oedema
• Enlarged tender liver
• JVP
• Pulse abnormalities
• Apex
• Cardiac murmur
• Exclusion of other causes e.g ascites and oedema
Management
• Diuretics
• Vasodilators
• Digoxin
• Treatment of primary cause
• Further evaluation by ECG, X-Ray, Echo cardiogram etc.
Palpitation
• It is the awareness of heart beat.
• Very common presentation of cardiac as well as non-cardiac disorders.
Diagnosed by-
• cardiac disorders diagnosed on following basis-
Pulse e.g >140 beats/min Apex beat Cardiac murmurs
• Suddenness of appearance and disappearance
• Confusion with panic attack
Management
• Tachyarrythmias
Valsalva maneuver
Carotid massage ( uni -lateral)
Drugs e.g
b- blockers , verapamil , digoxin
Defibrillation
Brady-arrythmia
• Efforts should be made by- Anti- cholinergic drug e.g atropine,propantheline Sympathomimetic drugs e.g. aminophylline • Refer to hospital for further evaluation and
management
Peripheral Thrombo -embolism
Diagnosed by-
Sudden severe pain in limbs or in any target organs
Absence of pulse of involved regions having cardiac abnormalities
Management
• Rest
• Aspirin
• Low molecular wt. heparin(s/c)
• Avoidance of risk factors
• Transfer to hospital in a proper way.
Vasculitis
Diagnosed by
Intermittent claudication
Raynaud’s phenomenon
Ulceration
Gangrene
Treatment
• According to cause
• Symptomatic treatment
Vasodilators
Avoidance of preciptating
factors
Congenital heart disease
• Cyanotic spell
-Recurrent episodes of convulsion associated with cyanosis in case of congenital heart disease
• Recurrent Respiratory tract infection
• Failure to thrive
• Presence of murmur
Management
• Squatting posture
• Propranolol
• Treatment of recurrent RTI
• Refer to hospital
Surgical correction
Rheumatic fever
• 5 major criteria- Migratory polyarthritis
Carditis
Sydenhams chorea
Erythema marginatum
Rheumatoid nodules
• Minor criteria Arthralgia
High fever
High ESR
CRP
Prolongation of PR interval
Diagnosis

plus
evidence of streptococcal infection e.g raised ASO titre ,positive throat swab culture
Management • Rest
• Aspirin
• Steroid, if there is carditis
• In acute case- Inj Benzyl Penicillin 1.2 Million unit single dose or Oral phenoxymythylpenicillin 250 mg 6 hourly for 10 days
Prophylaxis
• Benzathine penicillin
• Phenoxy methyl penicillin
Haemoptysis
• Could be a presentation of
Mitral Stenosis (MS)
Pulmonary infarction
Acute LVF
• Diagnosis
In case of Mitral stenosis, murmur
Presenting condition for Pulmonary infarction e.g prolonged immobilisation, post-operative state
• Treatment
Antibiotic
Treatment of cause
Prolonged pyrexia • One of the important presentations of
Bacterial endocarditis
• Diagnosis should be suspected in a patient having cardiac lesions
Not responding to conventional anti microbial treatment
Exclusion of other causes of PUO
Treatment
• Identification of bacteria by blood culture
• Administration of at least two antibiotics e.g Flucloxacillin and Gentamicin for 4-6 wks
• Treatment of complications and treat according to the patient’s symptom.
Thrombophlebitis
• Diagnosed by Unilateral leg oedema, pain,fever
• Management Antibiotics
Rest
Anti-coagulants
Asymptomatic Cardiovascular disorders(incidental findings)
• Hypertension
• Valvular lesions
• Cardiomegaly
• Radiological or ECG abnormalities
Management
If asymptomatic no treatment but
time to time observation for any complication but patient should be informed and reassured.
Asymptomatic hypertension
• Hypertension is a common incidental finding.
• Diagnosis should be established by recheck.
• Proper measurement of BP is essential for diagnosis and should be repeated 5-10 minutes apart in a single setting and should be recorded at the last phase of examination.
Management
• Non-pharmacological Weight reduction
Avoidance of smoking
Relaxation
Exercise
Salt restriction
Pharmacological
Depends on TOD and ACC
Diuretics e.g thiazides
B- blockers, Ca Channel blockers
Combination of above two
ACE inhibitors
Vasodilators
Centrally acting sympatholytic drugs
Cerebrovascular Accident
Sudden neurological deficit with or without loss of consciousness due to cardiovascular abnormalities.
Diagnosis • Suddenness
• Having known cardiovascular disorders e.g HTN, MI, Valvular diseases
Other risk factors
No other precipitating causes of neurological dysfunction e.g drug, head injury
Management • General management of an
unconscious patient
Care of mouth, eyes, skin
Care of pressure sore
Care of airway
Fluid balance
Cont..
Care of bowel and bladder
Physiotherapy to protect muscles and joints contractures.
Monitoring
Control of infection
• Specific treatment To control BP ,DM and other
precipitating causes
Cardiac Neurosis Patient used psedomedical terms as a
complain, like
Low pressure
Heart Attack
Heart Disease
Heart fail e.t.c.
Management:
A good rapport with the patient and Reassurance and explanation
Conclusion
• Teaching should be problem based not on topic based.
• Doctors must be competent enough to address the cardiac emergences like Sudden Cardiac Death, Syncope or Dyspnoea at local setup promptly.
• They must learn when, how, where to refer after settling the acute condition.
Conclusion
• Doctors should be capable enough to individualise each patient and their local clinical facilities and feasibility of transportation to higher centre.
• BLS management training should be compulsory to all Doctors, paramedics.
• We also recommend basic life support management training should be included in general education.
