A blog around the causes and signs of heart attack and stroke and the steps you can take to avoid them.
Heart attacks and stroke are amongst the leading causes of death in the world. Both result from the obstruction of the blood vessels that supply the heart and brain, respectively. Each year, more than 17 million Americans will experience a heart attack, while more than 800,000 people are expected to suffer a stroke. This blog will look at some of the common causes of heart attack and stroke. It will also look at some of the signs and some preventative measures that you can take to help avoid these heart attacks and strokes.
1. Heart attacks and strokes - nature vs nurture
Heart attacks and strokes are both caused by the obstruction of blood vessels. However, they differ in the way they occur within the body and the nature of the blockage that ultimately leads to the death of the tissue. Heart attacks (myocardial infarction) occur when a coronary artery becomes blocked. These blockages are often the result of plaque buildup in the coronary artery, which is a known risk factor for heart disease and heart attacks. The plaque buildup can either come from a buildup of cholesterol or from blood clotting that occurs in the artery. Blood clotting is a result of damage to the blood vessel from smoking or high blood pressure. Most heart attacks usually occur in people who have no history of heart disease and are often associated with physical activity. A heart attack can also be a result of a heart condition that is not known but is a risk factor for heart disease.
2. Adoption of AI in heart attacks and strokes
A new study reveals that artificial intelligence (AI) can predict the onset of heart attacks and strokes. The study was led by Dr. Zahi Fayad and was published in the journal Nature Biomedical Engineering. The researchers used an AI algorithm known as DeepHeart to analyze electrocardiogram (ECG) and multimodal computed tomography (CT) images of more than 1,000 patients. The algorithm was able to predict the onset of heart attacks and strokes with 90% accuracy. ECG and CT scans are routinely used for diagnosing heart attacks and strokes, but the scans are typically taken after the onset of the ailment. By using DeepHeart, doctors and medical personnel can be made aware of the onset of a heart attack or stroke hours earlier – which gives them a chance to administer emergency care. The DeepHeart algorithm is designed to scan the data for anomalies. If the algorithm detects an anomaly, it then looks for a pattern in a patient's medical history that matches the anomaly. This helps the AI to predict the onset of a heart attack or stroke.
3. AI heart attack treatment
Artificial Intelligence (AI) is already being used to predict heart attacks, according to research conducted by the Mount Sinai Hospital in Toronto. In a study published in the Canadian Medical Association Journal, researchers were able to predict heart attacks up to three years in advance with an accuracy rate of 87%. The research, which was presented at the European Society of Cardiology Congress in Munich, Germany, included data from more than 2,000 patients and was built using data from the Ontario Health Insurance Plan and the Institute for Clinical Evaluative Sciences. The researchers hope that self-monitoring tools, like the Apple Watch, will be able to identify irregular heartbeats.
4. Using AI to predict a stroke
A new comprehensive study has presented a machine learning method that can predict the risk of stroke in patients on the basis of an electrocardiogram (ECG). The method was developed by researchers from the University of Adelaide. It is important to note that this study is only applicable to predicting the risk of stroke, and it cannot be used for predicting heart attacks. "There are some very important clinical differences between these two major cardiovascular events," says Matthew Becker from the University of Adelaide's School of Computer Science. "For example, heart attacks are generally caused by a blood clot but most strokes are caused by a blood clot or bleeding. Also, heart attacks tend to cause chest pain and shortness of breath, while stroke tends to cause loss of strength and coordination, as well as speech and language difficulties."
Conclusion:
Artificial Intelligence has the potential to significantly impact the way we manage and treat heart attacks and strokes.
