Classification of IschemicHeart Disease (IHD)

4/14/12

ANGINA PECTORIS• It is characterized by intermittent chest pain.• The pain may radiate to the neck, back, down and left arm.

4/14/12

ANGINA PECTORIS

4/14/12

ACUTE myocardialinfarction (MI)

• MI, popularly called heart attack , is necrosis of heart muscleresulting from ischemia.

ECG CHANGES INMYOCARDIAL INFARCTION

4/14/12

Chronic ischemic heartdisease

• Is essentially progressive heart failure as a consequence of ischemic myocardial damage.

• The heart isenlarged.

• Moderate tosevere

atherosclerosis

4/14/12

SUDDEN CARDIAC DEATH

4/14/12

SUDDEN CARDIAC DEATH(SCD)• Sudden Cardiac Death (SCD) is most commonly defined as

unexpected death from cardiac causes either without

symptoms or within 1 to 24 hours of symptom onset• The ultimate mechanism of SCD is most often a lethal

ARRYTHMIA, such as VENTRICULAR FIBRILLATION.

Risk factors of Ischemicheart disease

Muhammad ailani

4/14/12

Hypertension (high bloodpressure)

• blood pressure can vary with activityand with age

• healthy adult generally has a systolicpressure reading between 120 and130 and a diastolic pressure readingbetween 80 and 90 (or below)

4/14/12

Diabetes

• heart problems are the leading causeof death with diabetes

• case of non-insulin-dependentdiabetes also known as Type IIdiabetes

4/14/12

High blood cholesterol

• cholesterol is a fat-like substancecarried by blood

• liver produces all of the cholesterolto form cell membranes and to makecertain hormones

• Extra cholesterol -meats, eggs,andother similar products

4/14/12

obesity and overweight

• increased total cholesterol levels,high blood pressure, and anincreased risk of coronary artery

disease• Developing other risk factors for

heart disease:

- high blood pressure

- high blood cholesterol

-diabetes

4/14/12

Smoking

• smoking increases the risk of lungcancer

• increases the risk of heart diseaseand peripheral vascular disease

• increases the risk of stroke in peoplewho already have high bloodpressure.

ETIOLOGY

ü Coronary heart disease

ü Abnormal heart rhythms

ü Anemia

ü Coronary artery spasm

ü Heart failure

Heart valve diseaseü Hyperthyroidism

4/14/12

ü Cold weather

ü Exercise

ü Emotional stress

ü Large meals

4/14/12

PATHOGENESIS

Ø Your heart muscle is working all the time, so itneeds a constant supply of oxygen. This oxygenis provided by the coronary arteries, which carryblood.

Ø When the heart muscle has to work harder, itneeds more oxygen. Symptoms of angina occur

when the coronary arteries are narrowed or blocked by hardening of the arteries(atherosclerosis), or by a blood clot.

Ø Occurs after activity or stress

Ø Lasts an average of 1 - 15 minutes

Ø Is relieved with rest or a medicinecalled nitro l cerin

Symptoms

Ø Heart does not get enough bloodflow and 0xygen ~ Heart Attack

Ø Acute Coronary Syndrome, norelease of the enzyme andbiomarkers of myocardial necrosis

Ø Braunwald Classification:Ø Class I : Less 2 months without rest

Ø Class II : Next 48 hours + rest pain

Definitions

4/14/12

Etiology & pathogenesis

Ø Characteristic:Ø High frequency of pain

Ø Precipitated by progressively less exertion

Ø Episodes tend to be more intense and

– longer lasting than stable angina

Ø Pathogenesis:Ø Associated with plaque disruption + superimposed

partial thrombosis + distal embolization of thethrombus + vasospasm

Factors of etiology

Ø Factors of etiologyØ Supply-demand mismatch

Ø Plaque disruption or rupture

Ø ThrombosisØ Vasoconstriction

Clinical Features, Fate and Complication of Unstable Angina

4/14/12

Focused History &Physicalexamination

• There is chest pain in the :-substernal lesion orepigastrium radiating to neck-left shoulder and left arm.

• There is severe discomfort orpain.

• Anginal equivalents likedyspnoea and epigastricdiscomfort are also frequentlypresent.

• There is diaphoresis (increasedsweating), pale skin, sinustachycardia, third and fourthheart sound, basilar rales orcrepts, sometime hypotension.

4/14/12

•Angina starting within the past 2 months and

becoming more severe.

•Limiting their physical activity.

•Suddenly becoming more frequent, severe, or

longer-lasting or being brought on by less exertion

than before.

•Occurring at rest with no obvious exertion or stress.

Some say these symptoms may wake you up.

•Not responding to rest or nitroglycerin.

•Have other than common symptom is chest pain or

pressure symptoms like shortness of breath, nausea,and back or jaw pain (for woman).

PatientsComplaints:

ECG of unstable angina

4/14/12

ECG of unstable angina

• There is ST segment depression

•Rarely there is transient ST segment

elevation

• There may be T inversions

•Any new ST segment changes like

depression of even 0.05 mV may denote

increasing severity.

•New deep T wave inversions (more than 0.3

mV) may be significant, but usually T wave

changes are nonspecific.

Cardiac biomarkers for

4/14/12

•CK-MB and troponin (highly specific) are elevated

in MI and associated with increased risk of death.

•New cardiac markers are C-reactive protein, BNP

(B type nitriuretic peptide, CD-40 ligand etc.

Prognostic indicators

4/14/12

Prognostic indicators

• Of note, studies have shown that the

following are significant

prognosticators for poor outcome:

• Ongoing congestive heart failure

• Presence/history of poor left

ventricular ejection fraction (LVEF)

Risk factors for coronary artery

4/14/12

y ydisease include:

• Diabetes

• Family history of early coronary heartdisease -- a close relative such as asibling or parent had heart diseasebefore age 55 (in a man) or beforeage 65 (in a woman)

• High blood pressure

• High LDL cholesterol

Low HDL cholesterol

What is variant angina?

• Prinzmetal• A form of chest pain, pressure, or

tightness (angina)• Extremely rare• N.B; the American cardiologist Dr.

Myron Prinzmetal• A form of unstable angina

• No identifiabletrigger

• Occur in clusters

Clinical features•

Occurs at rest• Last for 5-30 mins( between 12 – 8 AM )• Painful headache & Raynaud’s

phenomenon• Elevation of ST segment ( must be

detected during attack, suggestingprovocative method)

4/14/12

• Generally good prognosis

• Needs follow-up by doctors

• Treated with Calcium channel blockerand nitrates(vasodilators)

• In coronary blockade, angioplasty maybe considered.

4/14/12

Complications

• During pain, Arrhythmia mayoccur( vent. Tachycardia, vent.fibrillations, heart block)

• Treatment of arrhythmia may causemedication reaction & intolerance.

• For angioplastic patient; plaque

recurrence, infection, medicationreaction.
