Heart Disease

Which of these people has heart disease???

objectives
At the end of this session today you will

Cite prevalence and incidence data of heart disease

Identify major ethnic and gender differences in heart disease prevalence and incidence

Identify the major structures of the heart, including atria, ventricles and valves

Understand the basis of the cardiac action potential

Objectives
prevalence
Prevalence
  • Heart disease, also called Cardiovascular Disease (CVD), is a number of abnormal conditions affecting the heart and blood vessels.
  • Worldwide heart disease kills more than 17.5 million people, which is 30% of all deaths.
    • Over 80% of chronic disease deaths occur in low and middle income countries.

The Heart: Anatomy
  • Layers
    • Pericardium
    • Myocardium
    • Endothelium
  • Two sides
    • Right
    • Left
  • Four chambers
    • Upper – Atria
    • Lower - Ventricles

The Heart: Anatomy
  • AV valves – between the atrium and ventricle
    • Right AV valve - tricuspid valve
    • Left AV valve – mitral valve
  • Pulmonary Valve
  • Aortic Valve

Pop Quiz
  • How much blood does the heart pump in a day?

a. 100 gallons

b. 1000 gallons

c. 2000 gallons

d. 5000 gallons

the heart as a muscular pump
The Heart as a Muscular Pump

Cardiac Muscle - striated due to arrangement of myosin and actin - adjacent cells are joined end to end by intercalated disks - adjacent cells are electrically linked by gap junctions

cardiac excitation
Cardiac Excitation

Conducting system of the heart

pop quiz21
Pop Quiz

How many times does the human heart “beat” (expand and contract) in a day?

a. 50,000

b. 100,000

c. 150,000

d. 200,000

cardiac action potential
Cardiac Action Potential

Ion channel permeability during Action Potential

electrocardiogram ecg or ekg
Electrocardiogram (ECG or EKG)
  • P – atrial depolarization
  • QRS – ventricular depolarization
  • T – ventricular repolarization
cardiac action potential24
Cardiac Action Potential

A. Clinical – EKG

B. Cellular - Action Potential

C

C. Molecular – Electrophysiology recordings
