Symptoms of Heart Disease

Symptoms of Heart Disease
No single can be branded as Symptoms of Heart Disease. Then it no one single reason that indicates a heart disorder. There are certain symptoms that suggest the possibility of heart disease. Together they make the diagnosis almost certain. Doctors identify Symptoms of Heart Disease by interviewing the person to obtain the medical history and by performing a physical examination. Often, diagnostic procedures are performed to confirm the result of the diagnosis. However, sometimes a heart disorder, even when serious, produces no symptoms until it reaches a late stage. Routine health checkups or a visit to the doctor for some other reason may uncover a heart disorder that has caused no Symptoms of Heart Disease, earlier. Sometimes doctors perform procedures to screen for a heart disorder even when there is no evidence of it.

The Symptoms of Heart Disease include certain types of pain, shortness of breath, fatigue, palpitation or irregular heartbeats, light-headedness, fainting, and swelling in the legs, ankles, and feet. However, these symptoms do not necessarily indicate a heart disorder. For example, chest pain may be due to a respiratory or digestive disorder rather than to a heart disorder. But as soon as you experience any of the above mentioned complains you must consult your doctor for confirmation. Peripheral Symptoms of Heart Disease and blood vessel disorders vary depending on where the affected blood vessels are located. These symptoms may include pain, muscle fatigue, muscle cramps, light-headedness, swelling, numbness, shortness of breath, and a change in skin color of the affected part of the body.

Chest pain is the most prominent Symptoms of Heart Disease. Immediately life-threatening causes include a heart attack, separation of the layers of the aorta's wall, that is known as aortic dissection, rupture of the esophagus, a blood clot in the lungs, and a type of collapsed lung in which pressure builds up enough to obstruct blood flow returning to the heart. Pain may occur when tissues do not get enough blood, this condition is called ischemia. Pain occurs because the tissues do not get enough oxygen that is carried to tissues by the blood, and also because waste products, which are carried away from tissues by the blood, accumulate. Other Symptoms of Heart Diseases are: Discomfort, pressure, heaviness, or pain in the chest, arm or below the breastbone, Discomfort radiating to the back, throat, jaw or arm, Extreme weakness, anxiety or shortness of breath, Rapid or irregular heartbeats, Fullness, indigestion or choking feeling, he may also feel heartburn, Sweating, vomiting, nausea, or dizziness.

During a heart attack, symptoms last for 30 minutes or longer and are not relieved by rest or oral medications. Initial symptoms started as a mild discomfort that then it progresses to significant pain. Swelling is due to the accumulation of fluid in tissues. Swelling is another important Symptoms of Heart Disease. It occurs when blood puddles in the leg veins, increasing pressure in the leg veins and forcing fluids out of the veins into tissues.

Heart palpitations at night


Why do we have heart palpitations at night?

Before we discuss the matter of heart palpitations at night, we have to clarify the meaning of the word “palpitation” in general. Palpitations refer to irregular heart beats, usually the heart beats to fast, or with pauses from time to time and gives us an abnormal sensation, sometimes associated with dizziness, light-headed sensation, shortness of breath, chest pain etc.
We all had palpitation at least once in our life, and this doesn’t mean we have a heart disease, because these symptoms occur in healthy people during exercise or associated to stress, smoking, coffee. Even so, if the palpitation persist or are associated with shortness of breath, chest pain, fainting, dizziness, a doctor should be consulted as soon as possible.
Some patients complain they have heart palpitations at night, which prevent them from falling asleep or wake them up in the middle of the night.


Heart palpitations at night -causes:

Normal heart rate for an adult is 60-90 beats/minute. If the heart rate is higher the 90 beats per minute, then the condition is called tachycardia and can provoke palpitation. Not only rapid heart rate can cause palpitation but also irregular heart beats, known as arrhythmia, which is the main cause behind palpitation. Why some patients experience heart palpitations at night, during rest, when heart labor is smaller?
Heart palpitations at night can be determined by one of the following cause:
  • too much stress and anxiety gathered during the daytime. It is a habit now that every time we go to sleep, we think again at the daily problems and try to find a solution, as it is said night is a good adviser. If your mind is concerned about certain problems happening in your life, you may be lying down and think about it over and over again, but the emotions and the psychical tension can generate palpitation.
  • excessive consumption of caffeine before sleeping can generate insomnia and palpitation, if you drink a lot of coffee, especially before sleeping, you may consider giving up.
  • smoking
  • alcohol consumption
  • medication-some drugs used to treat different diseases (like asthma, heart diseases, high blood pressure, cold) can determine palpitation: pseudoephedrine used in cold medication, theophylline for asthma etc.
  • pregnancy
  • fever-it is well known that body temperature elevation is associated with rapid heart beats and sometimes with palpitations
  • vigorous exercise before sleeping
  • breathing problems determined by lung diseases determine a low level of oxygen in the body, which can lead to heart palpitations at night
  • heart problem-patients with heart failure may develop paroxysmal nocturnal dyspnea (shortness of breath that occurs suddenly during night in patient with left heart failure) and palpitations, forcing them to wake up and search for an open window to get fresh air
  • hyperthyroidism (a higher level of thyroid hormones can determine irregular or rapid heart beats)
  • elevated blood pressure
If I have heart palpitations at night-how can my doctor discover if there is something wrong in my body?
Yes it is possible. For patients that have these symptoms only during night it is difficult to  diagnose them during a simple medical visit, but if a special device called holter ecg is used, then this is no longer a problem. Holter ECG is a portable medical device that the patient “wears” for 24 hours and it records heart activity during this period of time.
Heart palpitations at night-treatment
Heart palpitations at night can be treated only after proper tests are made in order to establish the correct diagnosis. In many cases, palpitations have no serious cause and a short time treatment associated with a life style change can be the “cure”.
Special precaution in patients with heart palpitations at night:
  • avoid consumption of alcohol, coffee, drugs (marijuana, cocaine) or smoking
  • avoid stress and anxiety-there are many types of techniques used against anxiety (psychotherapy, sports, taking vacation, travelling etc.)
  • sometimes medication is needed in order to control anxiety
  • respect your hours of sleep
  • avoid if possible the intake of medication that stimulate palpitations

Heart palpitations at night can be very uncomfortable, but sometimes a simple change in the  daily habits can make them disappear.

Fibrillation of the heart

Fibrillation of the heart

In the next part of the article we will discuss about fibrillation of the heart, one type of irregular heart rate and what are the consequences for our body. Our heart is an organ that has a so called „automatism”, an intrinsic property of the cardiac tissue to create its own electric impulse, a signal that allows changes in cell metabolism in order to generate cardiac muscle contraction and therefore pumping blood into the arteries. This electric signal is generated in the sinus node (a structure capable of generating electric signal, located in right atrium) and then conducted through special structures until it reaches the ventricles (heart chambers that pump blood into the arteries). If these structures called pacemakers, can’t function normally, irregular heart rate occurs and one of them is fibrillation of the heart.

 What is fibrillation of the heart ?

What is fibrillation of the heart? And how many types of fibrillation of the heart exist? There are two types of fibrillation of the heart: one is called atrial fibrillation and another ventricular fibrillation. The difference between these types of fibrillation of the heart is not just in name, but also in origin and prognostic. The first type of fibrillation of the heart-the atrial fibrillation-is an irregular heart rate generated in multiple atrial cells (but not in the sinus node which is the „natural” heart pacemaker).
Patients with atrial fibrillation may experience palpitations, shortness of breath, chest pain, dizziness, drowsiness, fainting, but there are some patients that don’t complain of any symptom and they are diagnosed with the occasion of a routine medical check or when the complications occur. Usually, atrial fibrillation allows blood clots to form and they can flow in the arteries and block them, causing a condition known as ischemia: the tissues won’t receive enough blood and oxygen and cells start to die. In this situation, strokes, pulmonary embolism (clots in the pulmonary arteries that can lead to death), limbs ischemia (if untreated it can lead to amputation) can occur and can lead to patient’s death, if immediate  measures aren’t taken. On the electrocardiogram, in atrial fibrillation there is an irregular heart rate, without „P” waves (which are a mark of  heart rate generated by the sinus node) and the frequency of the heart beats can vary: low, average or rapid.
If this arrhythmia was discovered at its beginning, a conversion to the normal heart rate called sinus rhythm can be tried (either using medication or with electric shocks). After this procedure succeeded, other medication is needed in order to maintain the normal heart rate, to control the normal frequency of the heart beats and prevent blood clotting. In some patients, when the beginning of this arrhythmia is unknown, doctors will use only drugs to control the heart rate (beta blockers like metoprolole, atenolol; digoxin-a drug that increases heart contractility and also has antuarrthymic properties, very often used in the treatment of atrial fibrillation, calcium channel blockers like amlodipine, verapamil, diltiazem) and prevent blood clotting. Atrial fibrillation associated with rapid heart rate can be a severe medical condition affecting the level of consciousness and the only way to save patient life is the electrical conversion to the sinus rhythm using electric shocks.
The other type of fibrillation of the heart-ventricular fibrillation is an irregular heart rate generated in the ventricular cells and is not compatible with life, meaning that is one of the heart rate that generates cardiac arrest. Heart stops from beating and emergency measures of resuscitation are needed-cardiac massage alternating with artificial oxygenation of lungs, using facial masks with balloons or orotracheal intubation (which is preferred if it is possible to perform), electric shocks, specific medication like adrenaline, vasopressin, amiodarone. If in 30-45 minutes all these maneuvers are unsuccessfully, then the patient is declared dead.

As we saw above, fibrillation of the heart is a major heart disorder, that requires  special attention, knowledge, maneuvers and skills, since ventricular fibrillation is the most frequent cause of cardiac arrest in adults.
