DEFINISI
Suatu sindroma klinik yang menandakan
adanya iskemia miokard akut, terdiri dari :
 Infark miokard akut Q wave (STEMI)
 Infark miokard akut non-Q (NSTEMI)
 Angina pektoris tidak stabil (UAP)
Ketiga kondisi ini sangat berkaitan erat, berbeda
hanya dalam derajat beratnya iskemi dan
luasnya miokard yang mengalami nekrosis.

PATOGENESIS
• Umumnya disebabkan oleh aterosklerosis
koroner
• Plak aterosklerosis ruptur  terbentuk
trombus diatas ateroma yang secara akut
menyumbat lumen koroner
• Apabila sumbatan terjadi secara total 
hampir seluruh dinding ventrikel akan
nekrosis

Risk Factors
Uncontrollable
Controllable
•Sex
•High blood pressure
•Hereditary
•High blood cholesterol
•Race
•Smoking
•Age
•Physical activity
•Obesity
•Diabetes
•Stress and anger

HISTORY
PRODROMAL SYMPTOMS
History very valuable to establish D/. Prodoma : chest discomfort –
unstable angina
1/3 symptoms for 1 – 4 wks
20% symptoms for < 24 hrs
Malaise, exhaustion
NATURE OF PAIN
• Most patients
severe prolonged,  30 minutes - hours
• Constricting, crushing, oppressing, compressing
heavy weight or squeezing in chest
• Choking, vise-like, heavy pain or stabbing, knife-like, boring or
burning discomfort
• Location : retrosternal, spreading frequently to both sides of the
chest with predilection to the left side
• Often pain radiates down ulnar aspect of left arm, producing
13
tingling sensation in left wrist, hand and fingers
NATURE OF PAIN
• SOME INSTANCES : pain begins in epigastrium, and simulates
abdominal disorder
• Sometimes pain radiates to shoulders, upper extremities, neck, jaw
and interscapular region favoring the left side
• Elderly : no chest pain but acute left ventricular failure and chest
tightness or marked weakness or syncope
• Pain arises from nerve endings in ischemic or injured, but not necrotic,
myocardium
OTHER SYMPTOMS
50% nausea or vomiting in transmural infarcts
Occasionally diarrhea, profound weakness, dizziness, palpitation, cold
perspiration, sense of impending doom
Occasionally : cerebral embolism or systemic arterial embolism

Anamnesis untuk UAP
• 3 kategori presentasi klinik UAP:
 Angina saat istirahat (resting angina)
 Angina awitan baru (new onset angina)
 Angina yang bertambah berat (increasing
angina)
• Riwayat penyakit dahulu :
 Riwayat angina on effort, infark
operasi pintas
 Riwayat penggunaan nitrogliserin
 Identifikasi faktor-faktor risiko

PHYSICAL EXAMINATION
GENERAL APPEARANCE
Anxious, considerable distress,
(Levine sign)
LV failure & symp. stimulation :
dyspnea, cough with frothy
sputum.
Shock : cool, clammy skin,
confusion or disorientation
restless, fist on chest
cold perspiration, pallor,
pink or blood-streaked
facial pallor, cyanosis,
HEART RATE
Variable depending on underlying rhythm and degree or
ventr. failure
Most commonly, HR 100 – 110/min; > 95% patients :
VPB’s within first 4 hours 17
BLOOD PRESSURE
Majority normotensive, but syst. BP may decline and diast.
BP may rise
 Half of pts with inferior MI  parasympathetic stimulation
: hypotension, bradycardia or both (Bezold – Jarisch
reflex)
 half of pts with anterior MI,  sympathetic excess :
hypertension, tachycardia or both
TEMPERATURE AND RESPIRATION
Most pts with extensive MI  fever within 24-48 hrs, fever
resolves by 4th or 5th day
Respiration  due to anxiety and pain, in LV failure : resp.
rate correlates with degree of heart failure
18
JUGULAR VENOUS PULSE
JVP usually normal
RV infarction : marked jug. venous distension
CAROTID PULSE
Small pulse  reduced stroke volume
Pulse alternans : severe LV dysfunction
19
CHEST
LV failure and/or LV compliance ↓ : moist rales
Severe failure : diffuse wheezing, cough + hemopthysis
1967 : Killip & Kimball : prognostic classification
Class
I
: patients free of rales or S3
II
: rales < 50% lung fields +/- S3
III : rales > 50% lung fields, frequently
pulm. edema
IV : cardiogenic shock
20
Pemeriksaan Penunjang
• Pemeriksaan EKG
Gambaran EKG infark miokard akut Q-wave (STEMI) :
 Elevasi segmen ST  1 mm pada  2 sadapan
extremitas
 Atau  2 mm pada  2 sadapan prekordial yang
berurutan
 Atau gambaran LBBB baru atau diduga baru
21
ST-segment elevation
Gambaran EKG infark miokard akut non-Qwave (NSTEMI) atau angina pektoris tidak
stabil (UAP) :
– Depresi segment ST atau gelombang T
terbalik pada  2 sadapan berurutan
– Inversi gelombang T minimal 1 mm pada 2
sadapan atau lebih yang berurutan.
– Perubahan segment ST saat keluhan dan
kembali normal saat keluhan hilang 
sangat menyokong UAP

(Cardiac Markers):
Yang lazim adalah CKMB, dapat pula troponin T (TnT)
atau troponin I (TnI)
Peningkatan marka jantung akan terlihat pada infark
miokard akut Q-wave (STEMI) dan non-Q-wave

Thank you for your attention
Anamnesis
• Nyeri dada atau nyeri epigastrium hebat yang mengarah
pada iskemia miokard :
 Seperti dihimpit benda berat
 Terasa tercekik
 Rasa ditekan, ditinju, ditikam
 Rasa terbakar
Biasanya dirasakan dibelakang stenum  seluruh dada
terutama kiri, dapat ke tengkuk, rahang, bahu,
punggung, lengan kiri atau kedua lengan
• Terutama laki-laki > 35 tahun dan Wanita > 40 tahun
• Seringkali disertai mual atau muntah, dapat pula rasa
tidak enak disertai sesak nafas, lemah, penurunan
kesadaran, dan keringat banyak
56
Pemeriksaan Fisik
• Biasanya penderita tampak cemas, gelisah, pucat, dan
keringat dingin
• Periksa tanda-tanda vital :
 Denyut nadi cepat, reguler tetapi dapat pula bradi
atau tachycardia, irama ireguler
 Tekanan darah biasanya normal bila belum terjadi
komplikasi, dapat pula terjadi hipo atau hipertensi
 Bunyi jantung dapat terdengar redup
 S3 dapat terdengar bila kerusakan miokard luas
 Paru-paru dapat terdengar ronkhi basah dan atau
wheezing yang menandakan terjadinya bendungan
paru  tergantung ada tidaknya gangguan fungsi
