By Dr. Ahmed
CardiologyPatients with Ischemic heart disease fall into two categories
1.Stable angina due to chronic Coronary Artery disease
2.Acute Coronary Artery Syndromes (ACS)

The latter group are compased of
a)Patients with acute myocardial infarction with ST-segment elevation
b)Patients with Unstable Angina and non ST segment elevation.

Unstable angina is defined as Angina or equivalant ischemic discomfort with atleast one of the three features -
1.It occurs at rest (usually lasting > 10 mins)
2.It is severe and of new onset
3.It occurs with a cresendo pattern(more severe,prolonged or frequentthan the previous attack)
Clinical presentation :


  • Chest pain - typically substernal region or epigastric discomfort that frequently radiates to neck,left shoulder or left arm.
  • Dyspnoea
  • Diaphoresis
  • Pale cool skin
  • Tachycardia(Increased heart rate)
  • Audible third or fourth heart sounds
  • Basilar rales
  • Sometimes hypotension


Electrocardiogram :
ST segment elevation or transient depression are seen.The presence of new ST segment deviation is an important predictor of adverse outcome.

Cardiac Biochemical markers :

  • CK-MB
  • Troponin (more specific)

Factors which corelate with increased moratality and recurrent cardiac events :

  • C-reactive protien
  • B-type natriuretic peptite
  • CD-40

In adolescence, there is increased secretion of sebum from sebaceous glands. The glands get blocked with the retained sebum and kerotinous debris. Small cysts called Comedons are formed due to blockage of hair follicles. Proprionobacterium acnes is the cyst and caused production of fatty acids within the cysts. Thus causing infection of the cyst and bursting of the cyst wall. The extrusion of oily, keratinous debris triggers a foreign body reaction develops. Comedones : These are of two types- Closed comedones = White heads. Opened comedones = Black heads. The closed comedones are mostly associated with inflammatory lesions like papules , cysts and nodules. These are seen as small white heads with the naked eye or sometimes are not visible to the naked eye. The Open comedones are seen as Black heads. These are more st...

Pathology- Cardiac Tumors

By Dr. Ahmed
Cardiac Myxoma: It is derived from the Mesenchyme and usually arise within the left atrium near the fossa ovalis. It restrict the blood flow to left ventricle. Shows constitutional signs of fever, weight loss and anemia. Microscopic picture- Stellate shaped cells in the myxoid background. Complications- Embolism (mostly in the brain), Ball valve obstruction of valves. Cardiac Rhabdomyomas: Benign tumour arising from myocardium.. Associated with Tuberous sclerosis . Metastatic Disease: Most commonly from Lungs. This is more common than primary cardiac tumors.
