## Cardiovascular Disease English ##
Heart disease: A silent threat
Cardiovascular diseases are one of the most threatening health problems of our time. You are in the world, the most common cause of death and challenge every year, millions of lives. According to the world health organization (WHO) died in the year 2017 alone, the world 17.8 million people to the consequences of such diseases, which corresponds to approximately 32% of all deaths. Also in Germany and Europe, lead to the mortality statistics.
What lies behind the term cardiovascular disease? It is a variety of conditions that affect the heart and the vascular system. The most common include:
Coronary heart disease (CHD): narrowing of the coronary arteries, which can lead to circulatory disorders.
High blood pressure (hypertension): A permanently elevated blood pressure of more than 140/90 mmHg.
Congestive heart failure: The heart loses its pumping capacity and can no longer supply the body with sufficient blood.
Cardiac arrhythmias: Irregular heart beat too fast (tachycardia) or too slow (bradycardia) may be.
Atherosclerosis, calcification and narrowing of the arteries that can cause heart attack or stroke.
Risk factors: What makes us vulnerable?
Many risk factors can be due to a healthy life-style affect. The most important include:
Smoking Increases the risk for heart attack and stroke.
Unhealthy diet: Too much salt, saturated fat and sugar damage the circuit.
Lack of exercise: Regular physical activity (at least 150 minutes per week) reduces the risk by almost a third.
Overweight and obesity: a Burden on the heart and blood vessels, and promote Diabetes.
Stress and psychological distress: depression and Burnout syndromes worsen the prognosis in the case of existing heart diseases.
Genetic predisposition: family history plays in some of the forms of a role.
Symptoms: when should you go to the doctor?
Often, heart bleeding disease first complaint. However, the following signs should always be taken seriously:
Chest pain or tightness (especially under load)
Shortness of breath
Dizziness or fainting
Heart palpitations or irregular pulse
Swelling of the legs (signs of cardiac failure)
Particularly in women, acute events such as heart attacks are often atypical, Instead of the strongest chest pain, Nausea, abdominal discomfort, or General weakness occur. Therefore, education is important.
Prevention and treatment: What can you do?
The good news: Many cardiovascular diseases are preventable. The prevention is based on the following points:
Diet: More fruits, vegetables, whole grain products, fish and nuts; less salt, sugar and processed foods.
Regular exercise: walking, Cycling, Swimming or sports with a stamina character.
Smoke disclaimer: Immediate waiver reduces the risk quickly.
Stress management: relaxation techniques, Yoga, Meditation, or psychological support.
Regular checkups: measurement of blood pressure, blood sugar and cholesterol tests from the age of 35. Years old.
If a disease is already present, there are several treatment options: medication for blood pressure lowering, cholesterol-lowering drugs, Anticoagulation or, if necessary, surgical interventions, such as stent implantation or Bypass surgery.
Conclusion
Cardiovascular diseases are a serious challenge for the health systems in the world, but you do not need to be. By a conscious lifestyle, early diagnosis and targeted prevention measures, the individual risk can be reduced significantly. It is in our hands to protect our heart — before it's too late.

My sudden blood pressure diagnosis came at a time when I was too stressed. I was getting frequent headaches but always associated with long hours in front of the screen. Dr. told me to control my blood pressure with medicines, lifestyle changes and diet, or I could get a stroke. My husband bought me Cardio Balance to help me lower down my bp naturally. He was the one who monitored my reading. And to our amazement, it reduced from around 145/115 to 124/82 and stayed there. Honestly, it’s a lifesaver for me. <a href="http://urs-certification.com/gais/image/3332-scale-calculator-quickly-cardiovascular-diseases.xml">Cardiovascular Diseases-Biology Class 9</a> Cardiovascular Diseases
The cardiovascular System plays a Central role in the health of the human body: It ensures that oxygen and nutrients are transported to all organs and tissues, while at the same time waste products (to be removed as carbon dioxide). Unfortunately, diseases of this system are today one of the most common health problems and the leading cause of death in many developed countries — including Germany.
What is cardiovascular disease?
Among cardiovascular disease refers to any disease of the heart, blood vessels, or both relate to. The most important include:
High blood pressure (hypertension): The blood pressure is permanently increased, which increases the workload on the heart and blood vessels.
Arteriosclerosis (hardening of the arteries): To the inside of the artery walls deposits that restrict the flow of blood to form fat.
Heart attack: By a blockage of a coronary vessel, a part of the heart muscle dies.
Stroke: A vessel in the brain is blocked or burst, so that the brain tissue is not enough oxygen is supplied.
Congestive heart failure (heart failure): The heart is not pumping hard enough, which can lead to fluid retention and shortness of breath.
Risk factors
Many cardiovascular benefit diseases caused by certain lifestyle factors. The most important risk factors are:
The vessel Smoking: causes Damage to interior walls and promotes atherosclerosis.
Overweight and unhealthy diet: Too many saturated fatty acids and salt raise cholesterol levels and blood pressure.
Lack of exercise: Reduces the heart and circulatory efficiency.
Strong Stress Can lead to lasting hypertension.
Genetic predisposition In some families, circulatory problems occur more often.
Symptoms
Often, the first symptoms do not show until late. Typical signs are:
Chest pain (especially under load)
Shortness of breath
irregular or fast heartbeat (tachycardia)
Dizziness or fainting
swollen legs (signs of cardiac failure)
Prevention and healthy life style
Because many cardiovascular diseases are influenced by life-style, you can contribute a lot to prevent:
Regular physical activity: 30-60 minutes a day (e.g., Walking, Cycling, Swimming).
Balanced diet: Lots of fruits, vegetables, whole grains and low-fat dairy products; low in salt, sugar, and processed meat.
Waiver of Smoking and excessive alcohol consumption.
Stress management: relaxation techniques such as Yoga or Meditation.
Regular health examinations: blood pressure measurement and cholesterol tests from the age of 40. Years of age (or earlier at family risk).
Summary
Cardiovascular diseases are serious diseases that can often be avoided by a healthy lifestyle or mitigated. The Knowledge about risk factors and early symptoms helps to take timely measures to protect their own health in the long term.

## Calculation of the risk of cardiovascular diseases ##
Calculation of the risk of cardiovascular disease: prevention starts with Knowledge
Cardiovascular diseases are among the leading causes of death worldwide — and yet, a majority of the cases by targeted prevention to prevent it. A crucial role in the early risk calculation plays: it makes it possible to identify individual risk factors and targeted against them.
What is risk analysis?
The calculation of the risk for cardiovascular diseases (in short: the heart of risk) is a medical procedure, which is able to estimate the likelihood of developing within a certain period of time — typically 10 years — of a cardiovascular disease (such as heart attack or stroke). Various parameters are taken into account:
Age and sex: With increasing age, the risk increases; men are generally affected earlier and stronger than women.
Blood pressure: high blood pressure (hypertension) charged to the blood vessels and increases the risk significantly.
Cholesterol levels: in Particular, increased levels of LDL cholesterol (the bad cholesterol) promotes atherosclerosis.
Smoking: nicotine and other substances in tobacco smoke to damage the inner vessel wall and promote the formation of deposits.
Diabetes mellitus: high blood sugar levels damage the blood vessels in the long term.
Family history: A history of early cardiovascular disease in close Relatives increases the individual's risk.
Physical activity and nutrition, lack of exercise and a fat‑ and sugar-rich diet are important risk factors.
What models are there?
One of the most widely used models for risk calculation of the SCORE algorithm (Systematic COronary Risk Evaluation) is. It was developed by the European society of cardiology and determined the 10‑year risk of a fatal cardiovascular event. The model distinguishes between men and women as well as between countries with low and high cardiovascular risk.
For younger people or for the calculation of the absolute risk (including non‑fatal events), other models, such as the QRISK or the Framingham Score.
Why is risk so important?
The early identification of increased risk provides targeted primary prevention. That is: before a disease outbreak, measures can be taken to prevent it:
Reduction of blood pressure in hypertension
Cholesterol-lowering medication (statins), or change in Diet
Stop Smoking
Promoting physical activity and healthy nutrition for weight loss
Blood sugar control in Diabetes
A high individual risk is not a death sentence, but a warning signal and at the same time a Chance to take your health in Hand.
Conclusion
The calculation of the cardiac risk of diseases is not an end in itself, but an important tool for the prevention of cardiovascular disease. It makes the abstract concept of health risk tangible and motivated many people to change their behavior over the long term. Regular health examinations, in which the cardiac risk is identified, there should therefore be an integral part of our health care — because prevention is the best medicine.
