The origins of the Mass Rapid Transit (MRT) are derived from a forecast by city planners in 1967 which stated the need for a rail-based urban transport system by 1992.he lines are built by the Land Transport Authority, a statutory board of the Government of Singapore, which allocates operating concessions to the profit-based corporations, SMRT Corporation and SBS Transit. These operators also run bus and taxi services, thus facilitating full integration of public transport services.
A silent heart attack is a heart attack that happens without causing noticeable symptomsâor at least, without causing symptoms so severe that the victim cannot ignore them. Most of us tend to think about a myocardial infarction (heart attack) as a pretty dramatic eventâand most of the time, it is.
Symptoms of a silent heart attack can include discomfort in your chest, arms or jaw that seem to go away after resting, shortness of breath and tiring easily. The most common complaint of visitors to the emergency room is Chest Pain which is by far the most symptom you're having a heart attack.he most important treatment in silent heart attack is restoring the blood flow to the heart. Restoring blood flow can be accomplished by dissolving clots found in the artery (thrombolysis) or by pushing the artery open using a balloon (angioplasty). Both thrombolysis and angioplasty may be used at the same time.
