ATHEROSCLEROSIS and CARDIOVASCULAR DISEASE

ATHEROSCLEROSIS and CARDIOVASCULAR DISEASE


ATHEROSCLEROSIS and CARDIOVASCULAR DISEASE

The WHO lists cardiovascular diseases (CVDs) as the number 1 cause of death globally, taking an estimated 17.9 million lives each year. Four out of five CVD deaths are due to heart attacks and strokes, and one third of these deaths occur prematurely in people under 70 years of age (https://www.who.int/health-topics/car…)

Cardiovascular disease, or CVD, refers to a variety of health problems with the heart or blood vessels, including heart attacks, heart failure and stroke. The underlying defects remain incompletely understood and asymptomatic vascular damage can accumulate for years before patients are diagnosed.

Risk factors include
* high blood pressure,
* unhealthy eating habits,
* lack of physical exercise,
* smoking and alcohol consumption

The build-up of plaques in blood vessels referred to as atherosclerosis remains the best understood cause for CVD, but little is known about the origin of these plaques and their specific forms, which may be more or less stable. There is no better therapeutic strategy to prevent CVD than living a healthy life. The American Heart Foundation (https://www.heart.org/en/healthy-living) suggests besides eating right and being physically active, that real health includes getting enough sleep, managing stress, and connecting socially.

4.68 -> cardiovascular disease or CVD refers to  a variety of problems with the heart or  
10.95 -> blood vessels including heart attacks, heart  failure and stroke. Together they are the  
16.8 -> number one cause of death globally, estimated  at nearly 18 million deaths in 2015 and rising.  
26.75 -> Initial symptoms, such as unexplained chest  pains or exhaustion after only moderate  
32.09 -> physical exertion are frequently ignored  and thus many patients are only treated  
37.13 -> after suffering a heart attack or stroke. The aim of the EU funded project SYSVASC was  
44.15 -> to use a systems medicine approach to better  understand the development of CVD and defined  
49.97 -> so-called biomarkers for it. Researchers hope that  by using a comprehensive collection of clinical  
57.31 -> and experimental data to generate computer  models of the disease, they could identify  
62.38 -> novel molecular targets suitable for early disease  prediction. In many cases cardiovascular disease  
70.09 -> is caused by the chronic inflammatory condition  atherosclerosis. Due to unhealthy eating habits  
76.21 -> and a lack of exercise deposits of fat  cholesterol and other substances present  
81.7 -> in the blood build up over many years inside  the arteries. White blood cells are attracted,  
87.58 -> triggering an inflammatory process over time the  resulting plaques cause the arteries to narrow  
93.85 -> and harden obstructing blood flow. However not  all patients appear to have stable plaques which  
101.29 -> build up and eventually limit blood flow some  patients suffer from unstable plaques which  
106.9 -> pose an additional threat. Unstable plaques are  prone to sudden rupture which causes local blood  
113.89 -> clotting and may even completely block vessels  if this happens in the coronary artery the heart  
120.46 -> may become starved of oxygen resulting in the  death of cardiac muscle cells and heart attack.
135.7 -> Physical exercise in the healthy diet prevent  all forms of CVD, while drinking and smoking  
141.64 -> are risk factors. As atherosclerosis progresses  patients are increasingly exhausted after physical  
149.17 -> exertion, while severe cases cannot participate in  everyday activities like walking uphill. Currently  
156.88 -> clinicians do not fully understand why CVD  progresses faster in some patients than in  
162.43 -> others. We know from studying tissue that unstable  plaques have a thin fibrous cap over a large lipid  
169.39 -> core while stable plaques have thick fibrous  caps, that prevents premature rupture. Modern  
175.96 -> therapeutic options are available for patients  with CVD to reduce the risk of plaque progression  
181.6 -> or rupture. But how can we identify the patients  who would benefit from such a treatment? Diseased  
188.29 -> arteries and plaques release molecules into the  blood stream, the SYSVASC consortium set out to  
194.74 -> understand how CVD develops and to identify new  targets for therapeutic intervention. Therefore  
201.31 -> the SYSVASC consortium used methods such as mass  spectrometry to analyze large numbers of blood  
207.94 -> and tissue samples from patients at different  stages of cardiovascular disease to uncover their  
213.43 -> molecular composition. SYSVASC researchers have  employed sophisticated methods to identify new  
219.82 -> biomarkers which correlate with the severity of  vascular damage. While this work is still ongoing  
225.85 -> substantial progress has already been made towards  identifying molecular targets and a specialized  
232.06 -> cardiovascular disease knowledge base is available  to support this research. Promising candidates  
237.94 -> are being tested for their impact on disease  progression as we speak. Using the tell-tale  
243.77 -> molecules that we hope to find clinicians in the  future will be able to identify patients with  
249.56 -> unstable plaques. This would allow these patients  to receive preventative therapy to interfere with  
255.86 -> the catastrophic and currently unpredictable  events leading to stroke and heart attack.
