A smartphone application could detect a blocked blood vessel in your neck, brain, heart etc, that could cause a stroke, a new study suggests. Yes it’s true, a videos may provide a non-invasive way to screen people who are at risk of stroke.
Nearly 87% of strokes are the ischemic type, which happens when fatty deposits build up in the carotid artery in the neck, blocking blood supply to the brain.
Motion analysis of video recorded on a smartphone accurately detected narrowed arteries in the neck. Analysis of video recorded on a smartphone is non-invasive and easy to perform, so it may provide an opportunity to increase screening, the recordings and motion analysis may be able to be implemented remotely, or a downloadable app may even be feasible.
The changes in speed and pattern of blood flow through arteries just under the skin’s surface are too subtle to be seen by the naked eye. Motion magnification and pixel analysis detects tiny changes in pulse characteristics on the skin’s surface in smartphone videos.
The 202 Taiwanese adults who participated in the study had all received care at a single hospital. The study showed that about 54% had significant carotid artery stenosis, meaning their artery was at least half blocked, as diagnosed by ultrasound. The other participants did not have a significant blockage.
The researchers used an ordinary smart android phone to shoot 30-second videos of the patients’ necks. During the recordings, participants laid on their backs, with their heads tilted back in a device to minimize movement.
A video motion analysis algorithm detected stenosis with an 87% accuracy rate in the group that had already been diagnosed by ultrasound.
More research is needed to determine whether video recorded on smartphones is a promising approach to help expedite and increase stroke screening. Carotid artery stenosis is silent until a stroke happens. With this method, clinicians may be able to record a video of the patient’s neck with a smartphone, upload the videos for analysis and receive a report within five minutes. The early detection of carotid artery stenosis may improve patient outcomes.
The study was limited in that the number of participants was small and all were at high risk for a cardiovascular event. In addition, neck length and neck angle were not analyzed, which may affect the results of the video analysis. Scientists thinks that the skin color will not likely to limit the applications of this research to a broader population because a standard lighting method is using by the phone.
What Is a Stroke?
Common causes of stroke come from blood vessels both outside and inside the brain. Atherosclerosis (hardening of the arteries) can occur when plaque (deposits of cholesterol, calcium, non-organic fat, and other substances) builds up and narrows the vessel, making it easy for clots to form and further occlude the vessel. The clots can break free only to travel to and block smaller vessels inside the brain. The blood vessels inside the brain itself can accumulate this plaque. Occasionally, weakened vessels can burst and bleed into the brain.
A stroke, also known as a cerebrovascular accident or CVA is when part of the brain loses its blood supply and the part of the body that the blood-deprived brain cells control stops working. This loss of blood supply can be ischemic because of lack of blood flow, or hemorrhagic because of bleeding into brain tissue.
A strokes can lead to death or permanent disability. There are opportunities to treat ischemic strokes but that treatment needs to be started in the first few hours after the signs of a stroke begin.
A transient ischemic attack (TIA or mini-stroke) describes an ischemic stroke that is short-lived where the symptoms resolve spontaneously. This situation also requires emergency assessment to try to minimize the risk of a future stroke. By definition, a stroke would be classified as a TIA if all symptoms resolved within 24 hours.
Symptoms of Narrowed Arteries and Smartphone
Initial symptoms of a stroke can occur in someone suddenly. Know these signs of a stroke:
- Difficulty speaking
- Difficulty understanding or confusion, especially with simple tasks
- Difficulty with muscle strength, especially on one side of the body
- Numbness, especially on one side of the body
- Severe headache
- Vision changes (in one or both eyes)
- Difficulty with swallowing
- Facial droop on one side
F.A.S.T. Test
- F means face: If one side of the face droops, it’s a sign of a possible stroke
- A means arms: If the person cannot hold both arms out, it’s another possible stroke sign
- S means speech: Slurring words and poor understanding of simple sentences is another possible stroke sign
- T means time: If any of the FAS signs are positive, it’s Time to call an ambulance.
Remember the FAST test for stroke. The “T” in FAST also means the longer the brain is blocked from its blood supply (usually due to a blood clot), the greater the brain damage possible.
For many patients, the time limit to diagnose and treat such a clot is usually within 3 hours (some physicians suggest a bit longer). In some qualified patients, the use of a clot-busting drug may be used to dissolve the clot and restore blood flow. Not all patients qualify for this treatment. There are also some risks like bleeding associated with this treatment that may cause problems.
Diagnosing with Smartphone Narrowed Arteries and Types of Strokes
There are two main types of strokes (ischemic and hemorrhagic) and in allopathy as well as in Homeopathy, they are treated differently. They are often emergently diagnosed by a head CT scan (or an MRI scan).
Ischemic Stroke
Ischemic strokes are caused by clots that reduce or stop blood flow to the brain. The clot may develop elsewhere in the body and circulate to become lodged in a blood vessel in the brain, or the clot may originate in the brain.
Ischemic strokes are usually divided into two main subtypes: thrombotic and embolic.
Thrombotic Stroke
Thrombotic strokes are caused when blood clots form in the brain due to a diseased or damaged cerebral artery. Nearly half of all strokes are thrombotic strokes.
Embolic Stroke
Blood clots also cause embolic strokes. In the case of embolic strokes, the blood clot forms in an artery outside the brain. Often these blood clots start in the heart and travel until they become lodged in an artery of the brain. The physical and neurological damage embolic strokes cause is nearly immediate.
Hemorrhagic Stroke and Smartphone and Narrowed Arteries
A blood vessel in the brain breaks open, and blood escapes into the brain under pressure, compressing other blood vessels and brain cells causing damage and death. This bleeding into the brain is difficult to stop and is more likely to be fatal. There are two types of hemorrhagic strokes: intracerebral and subarachnoid.
Intracerebral Stroke
Intracerebral (within the brain) and it refers to a stroke caused by a diseased blood vessel bursting within the brain. Intracerebral strokes are usually caused by high blood pressure.
Subarachnoid Stroke
A subarachnoid hemorrhage refers to bleeding immediately surrounding the brain in the area of the head called the subarachnoid space. The main symptom of a subarachnoid stroke is a sudden, severe headache, possibly following a popping or snapping feeling. Many factors can cause a subarachnoid stroke, including head injury, allopathic blood thinners, bleeding disorders and bleeding from a tangle of blood vessels known as an arteriovenous malformation.
Mini-Stroke (TIA)
“Mini-strokes” (also termed transient ischemic attacks or TIAs) are temporary blockages of blood vessels in the brain. TIAs can produce mild stroke symptoms that resolve. TIAs often occur before a stroke happens, so they serve as warning signs that the person may need stroke preventive therapy.
Mini Stroke Symptoms
- Confusion
- Weakness
- Lethargy
- Paralysis
- Facial droop
- Vision loss
Mini Stroke allopathic treatment
Treatment for a mini-stroke may include medication, changes in lifestyle, and possibly surgery to reduce the chances of another stroke occurring.
Surgery after Smartphone and Narrowed Arteries diagnosis
There are some surgical options for stroke prevention. Some patients have plaque- narrowed carotid arteries. The plaque can participate in clot formation in the artery and can even shed clots to other areas in the brain’s blood vessels. Carotid endarterectomy is a surgical procedure in which the surgeon removes plaque from the inside of the arteries to reduce the chance of strokes in the future.
Balloon and Stent
Some doctors also treat plaque-narrowed carotid (and occasionally other brain arteries) with a balloon on the end of a narrow catheter. Inflating the balloon pushes plaque aside and increases the vessel’s lumen (opens up the vessel). This opened artery then is reinforced (kept open) by an expandable stent that, when expanded, becomes rigid.
Emergency stroke allopathic treatment
Emergency stroke treatment depends on the type of stroke and underlying health of the patient. Ischemic strokes are treated by methods designed to remove (dissolve) or bypass a clot in the brain, while hemorrhagic strokes are treated by attempts to stop the bleeding in the brain, control high blood pressure, and reduce brain swelling. Hemorrhagic strokes are more difficult to treat.
Aspirin
Aspirin is part of a group of drugs called antiplatelet agents. Antiplatelet agents like aspirin help prevent blood cell fragments from sticking together and forming clots and are therefore helpful in preventing some forms of stroke. The American Heart Association recommends taking aspirin within two days of an ischemic stroke to reduce the stroke’s severity. For those who have had a mini-stroke, a doctor may recommend daily aspirin treatment.
TPA
TPA is a clot-busting drug that can be used to treat ischemic strokes. It is given through the arm as an IV and helps dissolve blood clots and improve blood flow through areas of the brain blocked by clots. TPA may help if it is used within three hours of a stroke taking place.
Prescribed Medications and Side Effects
Allopathic medicines are designed to lower risk by inhibiting clot formation (aspirin, warfarin and/or other antiplatelet medicines). Also, antihypertensive medications can help by reducing high blood pressure.
But almost 98% allopathic medications have severe side effects, so be very careful to prescribe allopathic medicines to your patients.
Stroke Prevention
Common conditions that increase a person’s risk for strokes include high blood pressure, elevated cholesterol levels, diabetes, and obesity. People can reduce stroke risks by addressing these problems.
Lifestyle Changes
People can also reduce their stroke risk by altering some aspects of their lifestyle. For example, people who stop smoking, begin a consistent exercise program, and limit their alcohol intake (two drinks per day for men, one per day for women) can decrease their risk.
Diet
One of the best ways to reduce stroke risk is to eat a diet that has low fat and low cholesterol to reduce the chance of plaque formation in blood vessels. Foods high in salt may increase blood pressure. Cutting back on calories can help reduce obesity. A diet that contains a lot of vegetables, fruits, and whole grains, along with more fish and less meat (especially red meat) is suggested to lower stroke risk.
The methods previously discussed that may prevent or decrease a person’s stroke risk are essentially the same for people who have had a stroke (or TIA) and want to prevent or decrease their chances of having another stroke. In summary, quit smoking, exercise, and if obese, lose weight. Limit alcohol, salt, and fat intake and get into the habit of eating more vegetables, fruits, whole grains, and more fish and less meat.
