Chest pain at rest
|
|
Nitroglycerin (NTG)
with CHF |
IV Dose-treatment of choice for CHF patients with ischemic heart disease
|
|
Nitroglycerin (NTG)
with MI |
Used with ASA (Aspirin) & thrombolytics in acute MI
|
|
Nitroglycerin (NYG)
Precautions: |
Headache
hypotension interaction with other drugs nausea syncope |

obtain history do not administer if within three days of use |
|
Beta Blockers
|
Inderal
Tenormin Lopressor |
|
Beta Blockers
ACtions: |
Depresses the pumping function of the heart
1)Decrease HR 2)Decrease BP 3)Decrease myocardial contractility 4)Decrease myocardial O2 consumption |
|
Lasix
Action |
Loop Diuretic
vasodilation just prior to diuresis (watch for hypotension) |
|
Lasix
Indication: |
Pulmonary congestion associated with left ventricular
|
|
Lasix
Dosage: |
20-40 mg IV
|
|
Thrombolytics
Actions: |
Dissolve clots
(clot Busters) USe of thrombolytic should be initiated ASAP after onset of pain |
|
Thrombolytics
Indications: |
Pain of AMI (acute Myocardial Infarction)
< 70 years old 6-12 hrs from onset of pain |
|
Thrombolytics
Precautions: |
Bleeding
Chest Pain Reperfusion dysrhythmias |
|
Thrombolytics
Contraindication |
Hemorrhagic stroke
Bleeding disorders |
|
ASA
|
Aspirin-Now one of our most important immdeiate interventions
|
|
ASA
|
Apirin alone started within 24 hours of onset of AMI reduces overall mortality to almost the same degree as thrombolytics
|
|
Acute COronary Syndrome
|
Acute MI
AMI=Necrosis of heart muscle |
|
Acute Coronary Syndrome
Precipitatin Events |
Rest, sleep, usual activities, morning hours
|
|
Acute MI
Signs and Symptoms |
1) Chest pain
2)Radiating pain to shoulders, arms,neck, jaw, or back 3)Prolonged "indigestion" 4)Absense of chest pain(Sometimes) |
|
Acute MI
Diagnosis: |
Based on patients history
signs and symptoms serial ACG's Blood chemistrys |
|
Blood chemistries of MI
|
cardiac enzemes, Troponin
|
|
Acute MI
Early Treatment |
1) O2 decreases extent of ST changes
2) cardiac monitor-VFib most common 3)IV access 4) Pain relief 5)ASA 6)Thrombolytic therapy |
