Objective:
To determine the door to thrombolysis time of patients who presented to the Adult Priority Care Facility of the Eric Williams Medical Sciences Complex from February 1-May 31, 2008.
Method:
The patients who presented to the Adult Priority Care Facility of the Eric Williams Medical Sciences Complex with cardiac type chest pain and ST segment elevation that met the international criteria and had positive troponin test were interviewed and their notes reviewed to obtain the relevant information.
Results:
Fifty-one patients were treated with ST segment elevation myocardial infarctions; 78.4% were thrombolysed. Patients were: 59.75 years old, 68.6% male and 66.7% were of East Indian extraction The average time to thrombolysis was 5 hours and 31 minutes from the onset of chest pain. The average door to thrombolysis time was 2 hours and 7 minutes with 20% of patients having a door to thrombolysis time of 30 minutes. The time to thrombolysis from the onset of chest pain and the door to thrombolysis times were adversely affected by the health facility to which the patient first presented
Conclusion:
The majority of patients presented within the thrombolysis window. Early recognition of symptoms of myocardial infarction and arrival at a healthcare facility is not being achieved by the majority of patients. The systems that are responsible for the transport, triage and treatment of patients who present with chest pain are inadequate and require urgent review and overhaul to achieve the goals outlined by the American Heart Association and the American College of Cardiologist.

Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...
Physiology of the Heart: The Cardiac Cycle
Diastole: The Relaxation Phase
During diastole, all four heart chambers relax. The atrioventricular (AV) valves open, and the semilunar valves close. This phase sees the lowest chamber pressures, promoting ventricular filling. Venous blood enters the heart through the...
Specialized Characteristics of Cardiac Muscles
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy reserves in...
Pathophysiology of Cardiac Performance
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
