Two Simple Tests That Can Detect Early Signs Of Clogged Heart Arteries
Two Simple Tests That Can Detect Early Signs Of Clogged Heart Arteries
Coronary heart disease and Stroke are one of the most common causes of death and serious illness in the world today. The good news is that doctors are getting so much better at detecting the underlying disease process, called atherosclerosis, so much more reliably.
Two tests in particular, carotid ultrasound, and CT Coronary Angiography was now able to identify atherosclerosis in your body long before it creates serious problems such as heart attack or stroke.
These tests are so valuable in patients with symptoms of heart disease (chest pain, shortness of breath, dizziness and palpitations), and also serve as wonderful screening tools in patients with a family history of heart disease or stroke, or in those with risk factors such as diabetes, high blood pressure, high cholesterol and more.
In this video, top cardiologist Professor Henein explains everything you wish to know about Carotid Ultrasound and CT Coronary Angiography.

5.299 -> we have a number of Investigations we
7.799 -> can use
8.639 -> the easiest one that is radiation free
12.48 -> ultrasound
14.519 -> for the corner circulation
16.56 -> that is very important that we just
18.24 -> talked about it now as a risk factor for
20.46 -> heart muscle disease it is
24.119 -> the circulation is deep in the chest so
26.4 -> it's very difficult for the ultrasound
28.08 -> probe to get clear images of the corner
30.84 -> arteries
32.04 -> therefore what we rely on for early
35.52 -> disease is to scan the Carotid
38.219 -> circulation
39.66 -> carotid circulation is the neck here and
43.379 -> when the arteries come to the angle of
46.02 -> the mandible the parallel artery by 4K
48.84 -> into two branches one goes inside the
50.76 -> skull to the brain the other outside the
52.44 -> skeletal scalp
54.719 -> so as soon as we put the probe in the
57.36 -> neck you have a very clear cross section
60 -> of the Carotid artery which demonstrates
62.719 -> the thickness of the innermost wall of
66.299 -> the Cross artery imagine we're talking
68.1 -> about a fraction of a millimeter
71.64 -> and you can accurately measure it
75 -> thickening of that part is the earliest
77.72 -> manifestation of atherosclerosis even
80.46 -> before plaque formation
83.64 -> then of course patients with Advanced
85.439 -> disease will have plugs all over the
86.939 -> place and you can measure them even they
89.1 -> might have obstruction
91.5 -> of one of the arches
93.36 -> but we are talking about early detection
95.1 -> here so
96.78 -> in summary carotid ultrasound scan is a
100.2 -> very simple it doesn't take more than
101.939 -> five minutes job and will provide clear
104.46 -> evidence for early disease
107.52 -> I must mention a very important trial
110.72 -> run in Sweden called VIP Visa
115.02 -> and that trial looked at a large
117.18 -> population of 30 000 individuals they
120.119 -> classified them into two groups one
122.46 -> group were allowed to look at their
125.579 -> carotidescome
127.2 -> before they put them on risk factor
129.84 -> control and the other group did not have
132.42 -> that chance
133.68 -> and it the trial proved clearly
136.92 -> that patience and GPS who had the
140.52 -> carotides can results in front of them
142.76 -> were persuaded significantly to adhere
146.64 -> to very very strict lifestyle control as
150.599 -> well as risk factor control and of
152.94 -> course what you expect
154.86 -> better outcome the second important
157.8 -> investigation is CT scanning of the
161.28 -> corner circulation
163.019 -> and this helps in measuring something
166.44 -> called coronary calcium score
170.04 -> which means the extent of calcification
173.16 -> of the corner arteries which again
176.519 -> represent hardening of the arteries one
178.44 -> and also calcification is a form of
182.04 -> atherosclerose whether it's clinical or
183.78 -> subclinical doesn't matter but as long
186.06 -> as it's there it's telling us that there
188.519 -> is an ongoing pathology
190.739 -> we have published lots of papers on this
193.019 -> subject in fact and we found out that
195.42 -> patients with coronate article
198.42 -> certifications if you put them on a
200.34 -> statins and you control the risk factors
202.26 -> the calcium score might increase further
205.739 -> but it does not increase because of
207.48 -> worsening of disease but it increased
209.879 -> because of further stabilization of the
212.58 -> pathology
214.019 -> and fibrosis if you like and the
216.06 -> calcification of the inflamed wall of
218.94 -> the coronary arteries which is great
222.2 -> who's associated with great outcome in
225.239 -> terms of events heart attacks angina and
229.68 -> hospital admission
231 -> so these are the two most important
233.48 -> Imaging investigations that assess
237.739 -> detecting a disease of the coronary or
240.659 -> carotid circulation someone might ask us
243.299 -> a question whether the two pathologies
245.819 -> in the Carotid and the coronary arteries
247.56 -> are related or not
249.18 -> since the two techniques are looking at
251.099 -> different things
252.72 -> they are related of course not very
255.12 -> closely
256.639 -> but once atherose growth is well
259.079 -> established in our body
260.519 -> you are very likely to find it
263.58 -> affecting the two circulations
268.7 -> [Music]
