What should not be eaten with coronary heart disease?
Coronary heart disease is a cardiovascular disease, essentially characterized by atherosclerosis in the coronary arteries. Therefore, foods that should be avoided are those that could further negatively affect vascular function and blood circulation. Specifically, foods high in cholesterol should be limited, particularly animal organs such as liver and offal from pigs and chickens, as these are the primary culprits in causing coronary artery atherosclerosis due to high blood lipids. Furthermore, foods rich in cholesterol like preserved eggs, crab roe, fish roe, and cream should also be consumed less frequently to prevent increased blood lipid levels and higher chances of atherosclerosis in the coronary arteries. Additionally, strong tea should be avoided as it may cause excitement, insomnia, and trigger heart disease. Also, it's advisable to avoid spicy foods and condiments such as chili peppers and mustard, as these can cause vasoconstriction and spasms, leading to angina or even myocardial infarction. Finally, smoking should be quit and alcohol intake should be limited, with individuals frequently experiencing episodes of coronary heart disease advised to abstain from alcohol completely.
What tests are done for arrhythmia?
The examinations required for arrhythmia are as follows: First, an electrocardiogram, which is the most important non-invasive diagnostic technique for diagnosing arrhythmias. Second, a Holter monitor test should be conducted, which records the electrocardiogram continuously over 24 hours to possibly capture the occurrence of symptoms such as palpitations and fainting, and whether they are related to arrhythmias. It clarifies the relationship between arrhythmias or myocardial ischemia attacks and daily activities, as well as their diurnal distribution characteristics, and can assist in evaluating the efficacy of medications and the condition of pacemakers to some extent. Third is the exercise test; if palpitations occur during exercise, an exercise test can assist in making a diagnosis. Fourth is the esophageal electrocardiogram, which is a useful non-invasive method for diagnosing arrhythmias. Fifth is the cardiac electrophysiological study, typically involving the placement of electrode catheters on the upper and lower parts of the right atrial wall, the tip of the right ventricle, the coronary sinus, and the His bundle area, with the electrical activity at these sites being simultaneously recorded using a multi-channel physiological recorder with 8-12 channels or more.
Is a cerebral infarction a stroke?
Brain infarction is a type of stroke, and in traditional Chinese medicine (TCM), stroke is categorized as an illness, differentiated as external and internal wind. External wind, as discussed in "Treatise on Cold Pathogenic Diseases," occurs due to external evil invasions, also referred to as the Gui Zhi soup proof. Internal wind belongs to diseases caused by internal injuries, also termed brain stroke or sudden stroke. Commonly, stroke refers to the type caused by internal injuries involving disorders such as the chaos of qi and blood, obstruction of cerebral vessels, or blood overflow in the brain. It is a cerebral neurological disease identified mainly by sudden fainting, hemiplegia, numb limbs, difficult speech, facial distortion, and unilateral numbness. This condition is characterized by a sudden onset, rapid changes, and is akin to the pathogen of wind favoring rapid and multiple changes. The type of stroke discussed here is akin to a brain stroke. Brain infarction refers to the obstruction in a brain artery caused by various emboli such as intracardiac mural thrombi, atherosclerotic plaques, tumor cells, fibrocartilage, or air traveling with the bloodstream. When collateral circulation fails to compensate, it leads to ischemic necrosis of the brain tissue in the supplied area, causing focal neurological deficits. Cerebral hemorrhage, on the other hand, refers to bleeding within the brain tissue not caused by trauma but due to the rupture of intracerebral vessels. Both cerebral hemorrhage and brain infarction often result in varying degrees of motor deficits, cognitive impairments, and speech and swallowing difficulties, collectively referred to in stroke cases. Hence, brain infarction is considered a type of stroke.
The difference between arteriosclerosis and atherosclerosis
Arteriosclerosis is a common and important type among a group of vascular diseases known as arteriosclerosis. The common characteristics of various arterioscleroses include thickening and hardening of arterial walls, loss of elasticity, and narrowing of the lumen. Atherosclerosis is a type of arteriosclerosis characterized by lesions starting from the arterial intima, subsequently involving the accumulation of lipids and complex carbohydrates, bleeding, thrombosis, proliferation of fibrous tissues, and deposition of calcium, along with gradual degeneration and calcification of the arterial media. Since the lipids accumulated in the arterial intima appear yellowish and mushy, it is termed atherosclerosis.
Does arrhythmia premature beat have danger?
Premature beats, also known as premature contractions, abbreviated as premature beats, are a type of early ectopic heartbeats. They can be classified according to their origin into sinus, atrial, junctional, and ventricular, with ventricular being the most common. Premature beats are a common type of ectopic rhythm that can occur on the basis of sinus or ectopic rhythms, such as atrial fibrillation. They can occur occasionally or frequently and may irregularly or regularly follow each or several normal beats, forming a bigeminy or trigeminy pattern of premature beats. Generally, sinus, atrial, and junctional premature beats do not involve rapid ventricular rates and are usually not life-threatening. Although most premature beats are functional and do not cause damage to the heart, some pathological premature beats occurring on the basis of structural heart disease may further induce arrhythmias. In particular, ventricular premature beats may provoke ventricular tachycardia or ventricular fibrillation and in severe cases, may lead to sudden cardiac death. Additionally, multifocal atrioventricular premature beats are often a precursor to atrial fibrillation.
Is heart palpitations a heart disease?
Palpitations are one of the main symptoms of cardiovascular disease, but they should not be equated with it. Some palpitations do not accompany arrhythmias and can also occur in normal people, especially when lying on the left side, which might be noticeable. It is commonly seen in normal individuals who are nervous and sensitive, as well as in some anxious people. Normal people might experience palpitations during intense exercise; these could be due to sinus tachycardia or a high-output circulatory state, but most other cases should be evaluated to exclude heart disease.
