Coronary artery disease is the most common cause of sudden cardiac death, accounting for up to 80% of all cases. Cardiomyopathies and genetic channelopathies account for the remaining causes.
How does sudden cardiac death occur?
Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs.
Does sudden cardiac death hurt?
A 2015 study in the Annals of Internal Medicine discovered that about half of patients who have a sudden cardiac arrest first experience symptoms like intermittent chest pain and pressure, shortness of breath, palpitations, or ongoing flu-like symptoms, such as nausea and abdominal and back pain.
What does sudden cardiac death feel like?
Usually, the first sign of sudden cardiac arrest (SCA) is loss of consciousness (fainting). At the same time, no heartbeat (or pulse) can be felt. Some people may have a racing heartbeat or feel dizzy or lightheaded just before they faint.
What medications can cause sudden cardiac death?
There is increasing suspicion that several drugs in four widely used classes of non-cardiovascular medications-fluoroquinolone and macrolide antibiotics, antipsychotics, and antidepressants- are pro-arrhythmic and thus increase the risk of sudden cardiac death.
Why do strokes happen in the shower?
Most people wet their head and hair first when bathing, but this can cause a rapid change in body temperature as your body adjusts to the temperature of the water. This temperature change may generate pressure and cause artery or capillary breakage.
Where do most cardiac arrests happen?
The location of Out of Hospital Cardiac Arrests (OHCA) most often occurs in homes/residences (70%), followed by public settings (18.8%), and nursing homes (11.2%). If performed immediately, CPR can double or triple the chance of survival from an out of hospital cardiac arrest.
What are the 5 warning signs of a mini stroke?

- Numbness/weakness on one side of your body.
- Dizziness or loss of balance.
- Trouble talking or understanding.

What is embolic shower?
Thus, there are infarctions in multiple vascular territories. This pattern of multiple, acute strokes in different vascular territories usually signifies a shower of emboli, typically from a cardiac source. In this patient, atrial fibrillation was later discovered to be the cardiac source.
Is it common to have a stroke on the toilet?
Results: A total of 108 patients (41 CI, 37 ICH and 30 subarachnoid hemorrhages) sustained a stroke in the toilet. The ratio of toilet-related stroke was highest in subarachnoid hemorrhages (14.3%), followed by ICH (7.3%).
