A heart attack does not always have obvious symptoms, such as pain in your chest, shortness of breath and cold sweats. In fact, a heart attack can actually happen without a person knowing it. This condition is known as a  silent heart attack , medically known as  silent ischemia , occurring due to the shortage of oxygen supply to the heart muscle. The causes of a silent heart attack are similar to that of a heart attack. 

They include- 

Conditions like: 
Obesity or excess weight 
Diabetes 
High Blood pressure 
High cholesterol 
Heart Diseases 
Lack of exercise 
Age, usually above 65 
Consumption of tobacco or smoking 
High consumption of alcohol 
A silent cardiac arrest makes one more vulnerable to another heart attack that could be fatal. Diagnosis: The only method to diagnose if you had a silent heart attack is through imaging tests, such as echocardiogram, electrocardiogram, Holter Monitoring or others. These tests can show certain changes which might be indicative of a heart attack. An analysis of one s overall health and the symptoms can aid in deciding whether few more tests are required. 

How would you prevent a silent heart attack? 
1.   Get your cholesterol and blood pressure count tested regularly. 
2.   Refrain from smoking. 
3.   Get your VO2 max checked regularly. 
4.   Live a healthy lifestyle: Refrain from smoking and excessive alcohol consumption; exercise daily, eat healthy. 
5.   Control high blood pressure, cholesterol, and diabetes 
6.   Be aware of your body and call on a doctor if you feel there s anything which is bothering you. 

If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Know Everything About Silent Heart Attacks

Lifestyle changes and unhealthy habits take a toll on one s physical and mental health resulting in many diseases. One such disease that is growing common is the stroke that occurs due to a sudden interruption of blood supply to the brain. As with any lifestyle disease, the chances of having a stroke can be reduced as well. Knowing the risk factors and taking appropriate measures can prevent you from a stroke attack. 

Read on to know the seven effective ways to prevent you from a stroke.

Opt for a healthy lifestyle: While smoking leads to an increased risk of suffering from a stroke, excessive consumption of alcohol not only triggers irregular heartbeats, but also high blood pressure, which can be a solid reason behind having a stroke. Therefore, leading a healthy lifestyle free from smoking and alcohol can help in preventing strokes.
Manage conditions: Whether it is diabetes or any other kind of illness which directly or indirectly give rise to the risk of having a stroke, dealing with one's underlying conditions is important. In case one is diagnosed with such a condition that can be responsible for a stroke, he or she must make it a point to keep that condition under control.
Lose weight: Obesity is often known to increase the complexities associated with a stroke such as diabetes and high blood pressure. Therefore, for those who are overweight, losing a few pounds can be really helpful in preventing the chances of having a stroke.
Keep blood pressure in check: High blood pressure often causes a stroke, if not controlled. It is referred to as the biggest contributor in causing a stroke by many. Lowering the high blood pressure or bringing it to normal levels can indeed be a great way of preventing a stroke.
Exercise regularly: Exercise not only contributes to lowering the blood pressure, but also helps to maintain body weight while ensuring the overall fitness of the body. Some light hand exercises or regular walking combined with proper diet can do wonders in preventing a stroke.
Have a proper sleep at night: Spending sleepless nights may increase the risk of stroke. Therefore, one must make it a point to maintain the necessary amount of sleep at night that can help in reducing stress and anxiety, while decreasing the chance of heart diseases as well as a stroke.
Never ignore the palpitations: Ignoring the palpitations is the last thing one can want to do, if he or she is willing to prevent the chances of suffering a stroke. Feelings of lightheadedness or shortness of breath, chest pain and abnormal heart beats can be warning signs for a stroke. Therefore, you must pay proper attention to these and deal with appropriate medications.
An otherwise healthy person can stay away from stroke by continuing a healthy lifestyle and following the tips mentioned above. However, if you have suffered a stroke earlier, then it becomes imperative to follow these tips along with supervised medical care.

Stroke - Can You Prevent It From Happening?

If you are facing difficulties in breathing, especially in the process of exhaling, you are suffering from emphysema. Emphysema is a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness. It occurs as a result of several triggers, smoking being the most common one. Emphysema is a type of chronic obstructive pulmonary disease. People with this condition struggle to exhale, which implies that there is some obstruction in the air flow. This disease has no permanent cure but by quitting smoking, you can stop it from getting worse.

Stages
The progression and severity of emphysema occurs with the staging systems. The staging of the condition can help in developing a prognosis.

The Gold emphysema staging system
Gold is a major emphysema staging system created by a group known as the Global Initiative for Chronic Obstructive Lung Disease. The amount of air a patient can exhale forcefully in one second is determined during this stage. It is also referred to as the forced expiratory volume or FEV1.

The staging is as follows:

Stage 1: Mild emphysema (FEV1 greater than 80% of normal)
Stage 2: Moderate emphysema (FEV less than 80%, but more than 50% normal)
Stage 3: Severe emphysema (FEV lesser than 50%, but more than 30% normal)
Stage 4: Extremely severe emphysema. (FEV lesser than 30% of normal or lesser than 50% normal, with low levels of oxygen in the blood.
The BODE emphysema staging system
The condition affects several abilities. The BODE index, an acronym for BMI (body mass index), obstruction, dyspnea (breathlessness), exercise capacity (health index) is another staging system for emphysema in which the emphysema s impact on several areas of life are measured. They include the following:

Body mass index (B)
Airflow limitation or obstruction (O), which is measured by pulmonary function tests
Breathless or dyspnea (D), which is assessed thoroughly via a questionnaire
Exercise capacity (E), which is measured to check how long a person with emphysema can walk in a span of six minutes
Life expectancy
The prognosis of emphysema is impossible to be determined in any person individually. The staging system helps to identify the severity of the condition, but the future cannot be predicted. Not many studies have been undertaken for the determination of the effects of emphysema on life expectancy. The best research that has been carried out included around 100 people, which is very less. The condition varies largely among people, even if they are in the same stage.

The statistics available on emphysema are not reliable enough for individuals who wish to know their life expectancy. It is considered that if a patient falls in a higher stage, his/her long-term life expectancy is less.

Causes and Symptoms of Renal Hypertension

High blood pressure is characterized by an increased force that the blood exerts on the blood vessels when it moves through the body. Renal hypertension is a blood pressure disorder where the arteries that carry blood to the kidneys become narrow, as a result of which the blood pressure through these vessels increases.

Causes

It is caused when the arteries that supply blood to the kidney get narrow or get blocked. This can cause the kidney to release specific hormones that signal the body to retain water and sodium. This can put additional pressure on the blood vessels which leads to increased blood pressure. It can also be caused by atherosclerosis which is characterized by hardening of the arteries. Improper development of the arteries can also lead to renal hypertension.

Symptoms

The symptoms of renal hypertension are:

Feeling confused
Blurred vision
Regular headaches
Bleeding from the nose
Gradual decline in kidney function
Possible long-term damage to the kidney
Feeling lethargic and drowsy
Loss of appetite
Dryness in skin
Muscle cramps
Breathing difficulties

Treatments

The diagnostic procedure for this disorder consists of blood, urine, doppler ultrasound and CT angiography or MR angiography tests. Treatments for this disorder usually include medications to ease blood pressure. Preventive measures include modifications in lifestyle such as following a proper diet, limiting smoking, restricting sodium or salt in the diet and following an exercise regimen. Steps should also be taken to reduce stress. Yoga and meditation are highly beneficial to control the condition. Sometimes intervention is needed in the form of PTRA and stenting.

High Blood Pressure and Kidney Disease - Causes and Symptoms!

Vascular disorders are disorders of the vessels in your body that carry either blood or waste products. The vascular system consists of the arteries (that carry blood away from the heart), veins (that carry blood to the heart) and lymph vessels (that carry waste products to be excreted from the body). The various diseases of the vascular or circulatory system are:

Peripheral Artery Disease: Peripheral arteries carry blood to the various organs and tissues in the body. Accumulation of cholesterol and fat in the vessels narrow the pathway for the blood to flow. This can impair blood flow to the tissues in the body and cause complications. Various medications used to lower cholesterol and blood pressure can also be used for peripheral artery disease.
Buerger's Disease: This disease causes obstructions in the veins and arteries in the legs. This can hamper blood supply in the toes and the feet. It causes pain and may require amputation in severe cases. Treatments for this disease include smoking cessation and medications to dilute blood vessels.
Aneurysm: An aneurysm is swelling in the blood vessel walls; it usually occurs in the aorta. The artery walls become fragile and are placed under a lot of stress; this may lead to a sudden rupture of the aortic vessels. This disorder is usually treated by surgical procedures.
Peripheral Venous Disease: Peripheral venous disease is characterized by damage to the valves that allows blood to flow in a single direction. Damaged valves can cause blood to flow backwards and therefore, accumulate. Treatments for this disorder are incorporating certain lifestyle habits such as quitting smoking and alcohol.
Blood clots in the veins: Blood clots may occur in the veins present inside the muscles of the thighs and lower legs which lead to deep vein thrombosis. You may be prescribed anti-coagulants, also known as blood thinners, to treat this disorder.
Causes
People with diseases such diabetes, high blood pressure, or kidney failure can be more likely to have vessel problems. Working with vibrating tools, being in cold temperatures, and smoking can worsen vascular problems. Causes of vascular disorders usually fit into one of 5 groups:

Traumatic, which occur after injury
Compressive, which occur when the pipes flatten
Occlusive, which occur when pipes are blocked
Tumors (growths) or malformations (deformed, tangled pipes), which may or may not be present at birth
Vessel spasms, which occur when abnormal control of vessels causes them to narrow
Symptoms
Symptoms of vascular disorders can include:

Pain
Abnormal color changes in the fingertips
Ulcers or wounds that do not heal
Hand problems when in cold temperatures or locations
Numbness or tingling of the fingertips
Swelling
Cool or cold fingers and/or hands

5 Common Vascular Disorders

Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.
