Normal heart sounds

Normal heart sounds are produced by heart valves movements during cardiac cycle (events that take place during a heartbeat). There are two  normal heart sounds which are usually heard during heart auscultation: sound 1 and 2. Before we go farther with explanations, it is better to clarify a few elementary terms in order to understand the rest of the description.
Our heart has four chambers called ventricle and atrium, atrium are the heart chambers located in the upper part, while ventricles are located in the lower part:

• there is a right atrium connected to the right ventricle, in this part of the heart there is blood with carbon dioxide, brought by cava veins from tissues; then blood from right atrium flows through tricuspid valve ( it is like a door between the right chambers of the heart, which is open only in specific moments of the cardiac cycle) into right ventricle,
• the left part of the heart has also two chambers-atrium and ventricle, they are separated by mitral valve and contain blood with oxygen, brought from lungs.

So-called right and left heart are separated by a wall called septum, in abnormal situation this wall can be interrupted letting blood to flow from one part of the heart to the other and this situation can also generate ab normal heart sounds, a murmur that we hear during auscultations.
When we listen heartbeats with a stethoscope we can hear the two normal heart sounds 1 and 2, followed by a pause. Next, we will explain a few terms about cardiac cycle: every cardiac cycle has two phases-the contraction called systole and a pause caused diastole. Why are these two phases of the cardiac cycle so important? The atrium contraction will make blood to flow into the ventricle, while ventricle contraction will „throw” the blood into the main arteries, aorta (this artery with its branches supplies with blood and oxygen all the tissues of the body) and pulmonary artery (the blood with carbon dioxide resulted from cell metabolism is brought to lungs to be oxygenated). The pause we hear is nothing else but the time that hearts needs to relax in order to fill the chambers with blood; in this pause heart muscle also receives blood, because as any organ its function depends on the oxygen supply. All these „events” happen very fast and the indirect prove for these are  the normal heart sounds we hear in the auscultation.

Normal heart sounds description

Finally, we get to the point where we can define the meaning of the normal heart sounds 1 and 2. Sound 1 is a low frequency sound heard at the beginning of the ventricular contraction (also called heart systole), and results from mitral and tricuspid valve closure. Once these valves are closed, the ventricle contraction starts, also the pressure in this chamber increases and the blood will flow into the main arteries. Another normal heart sound is sound 2, a high frequency sound, resulted from aortic and pulmonary arteries valve closure, and signifies the beginning of the heart diastole (the pause that follows heart contraction).
Other sounds we may detect in heart auscultation are sound 3 and 4; these are not considered normal heart sounds, with a few exceptions. Sound 3 is heard in the first part of the diastole (heart pause) and may be the result of tachycardia, heart failure etc. Sound 4 appears in the last part of the heart relaxation, in patients with hypertension, myocarditis (heart muscle dysfunction) or mitral valve narrowing
Normal heart sounds are heard in specific areas of the chest called auscultation areas. Another aspect we have to mention is that normal heart sounds can be more intense in younger persons, due to a thinner thoracic wall or in conditions of stress or in effort, because the blood speed increases.
Normal heart sounds indicate a healthy heart?
 Normal heart sounds are not necessary associated with a normal heart function, that’s why, beside this basic examination, doctors look for other signs, investigations, medical history and symptoms.

Please let the doctor decide if you have normal heart sounds, and never try to treat yourself.

Hyperlipidemia symptoms

What are the hyperlipidemia symptoms ?

Hyperlipidemia represents increasing levels of lipid or lipoproteins in the blood and hyperlipidemia symptoms can be varied from patient to patient. Hyperlipidemia is a metabolic disease and may include changes in cholesterol (blood fat levels), triglycerides (a type of blood fat) or lipoproteins. There are two main types of hyperlipidemia: hypercholesterolemia (which occurs most frequently) and hypertriglyceridemia.  Hyperlipidemia may be a risk factor for atherosclerosis, cardiovascular diseases (coronary artery diseases and peripheral vascular diseases), but can affect other organs such as pancreas.

Hyperlipidemia symptoms

Hyperlipidemia symptoms are usually absent from most of the patients, if this is the only change to the analysis of blood. This can be found at a routine exam that the patient makes. It can remain undiagnosed for many years.
Hyperlipidemia symptoms can include first deposits of cholesterol (known as xanthomas) that form under the skin (especially around the eyes). They may be the only symptom that indicate an increase in blood lipids. They can also form the Achilles tendon and the extensor tendons of the hands. Xanthomas may have varied sizes, from very small to several centimeters. The diagnose of xanthoma can be done by physical examinations and by determining blood cholesterol levels.
Chest pain may be another symptom for hyperlipidemia. This pain can be felt by the patient as chest discomfort located anywhere. Patients go to the doctor for the fear of a heart attack. Hyperlipidemia is a risk factor for atherosclerosis (deposition of fat in the arteries of large and medium) that causes coronary artery diseases manifested primarily through chest pain. Any organ in the thorax may be the source of pain (heart, lungs, esophagus, muscles or nerves).
Another symptom which may be included in the category of hyperlipidemia symptoms is hepatomegaly (increased liver beyond normal size, 12 inches). This may or may not be associated with increased spleen size.
One of the last hyperlipidemia symptoms is abdominal pain. This may occur in the right hypochondrium where it is located the liver or anywhere in the abdomen. Hyperlipidemia occurs in the liver as fatty liver disease caused by the deposition of fat in liver cells. Pain in the abdomen can originate from many organs (stomach, small and large intestines, appendix, spleen, liver or pancreas). Pain may be generalized or may be located in a single point. In many cases patients don’t go to a doctor and expect that the pain to go by itself.
Treatment of hyperlipidemia symptoms

Treatment of hyperlipidemia symptoms can be done with drugs or by dietary changes, weight reduction and exercise. If cholesterol and triglycerides are not very high and patients have no important hyperlipidemia symptoms, doctors advice patients dietary changes by reducing dietary fat, weight loss and moderate exercise daily.
If  lipids values may be lower without drugs then doctors recommend the use statins (drugs used to lower cholesterol) and fibrates (drugs used to lower triglycerides).
Conclusion
In conclusion there are no specific hyperlipidemia symptoms, but if discovered at a routine exam is better to be treated because it can have serious complications.

Marfan syndrome life expectancy

When we talk about Marfan syndrome should really talk about Marfan syndrome life expectancy because it is a disease that undiagnosed, timely can lead to the death of the patients.
Marfan syndrome is a genetic disorder (autosomal dominant) characterized by connective tissue damage. This syndrome includes multiple malformations of organs (bones, eyes, skin, intestines, heart and lungs).

Marfan syndrome symptoms

Most of the visible signs or symptoms occur in the skeletal system. The patients  suffering from Marfan syndrome are taller than patients without the disease and arachnodactyly ( very thin and long fingers). Another anomaly in the skeletal system is pectus excavatus (deformity of the anterior wall of the chest which penetrates inside sternum) and scoliosis (abnormality of the spine that consists of spine deformity in the form of the letter S). Other signs include abnormal joint flexibility and sometimes pain in joint.
The most important signs and symptoms  associated with Marfan syndrome are the cardiovascular symptoms. This are mitral or aortic valve prolapse (the most common heart valve abnormality) and aneurysm of the aorta.  Many patients with Marfan syndrom have some type of vision problems of which the most important are myopia (a visual anomaly in which distant objects appear blurred), glaucoma and cataracts. This can severely influence Marfan syndrome life expectancy.

Marfan syndrome life expectancy

Marfan syndrome life expectancy may be different from patient to patient. There is no treatment for the Marfan syndrome, but life expectancy may be influenced by monitoring and treatment of complications that can occur. Marfan syndrome life expectancy increased lately because of the advancement in medical techniques and appearance of new treatments.
Best way to expend Marfan syndrome life expectancy is tracking the aneurysm of the aorta and mitral valve prolapse. This is done by a cardiologist annual control for monitoring the health of the heart valves and the aorta. This is done by performing an ECG or another radiological method for the visualization of the anomaly (such as CT or MRI image). The goal of treatment in Marfan syndrome is to slow the progression of the aortic dilatation and to prevent the dissection of the aorta. Another goal of the treatment is to eliminate arrythmias and diminuate the heart rate.
The skeletal manifestations of this syndrome are also important for Marfan syndrome life expectancy. They can be serious and can affect patients life. To solve these problems are used different kinds of pain medication or muscle relaxants.
Because some of the Marfan symptoms of the spine may be asymptomatic, but serious if are not treated, they can be solved by surgery and thus increase the Marfan syndrome life expectancy.
Lung damage involves spontaneous pneumothorax and Marfan syndrome life expectancy depends on the volume of air in the pleural space.  It may resolve by itself or can be made by chest drainage.
Conclusion

Today patients with this syndrome needs to know is not the end of life and Marfan syndrome life expectancy can be good if patients are addressed in time to the doctor.
