Heart problems are often fatal. In Germany include heart disease among the leading causes of death. Around 40 percent of all deaths in Germany can be traced back to chronic ischemic heart disease (ie lime deposits, which constrict the vessels). Around 300,000 Germans suffer a heart attack every year like that German Heart Foundation communicates. In the event of a heart attack, there is immediate danger to life – but what if you don’t even know what danger you are in? Researchers assume that almost two-thirds of heart attacks run subclinically and are overlooked in routine medical examinations.
Silent heart attack: With these symptoms, things get serious
But what is a silent heart attack? One large-scale cohort study from 2016 examined more than 9000 people over several years. After almost a decade, 703 subjects had suffered a heart attack. Only every second infarction was also recorded. The problem: The symptoms of a silent heart attack are very weak. Nevertheless, the consequences can be serious. the German Heart Foundation warns of the following symptoms and recommends a medical examination:
- Chest pain and pressure
- shortness of breath
Heart attack without symptoms: Why do many courses remain undetected?
When doctors breastfeed such Diagnose heart attacks, often weeks, months or even years have passed. In a silent heart attack, dying due to circulatory disorders parts of the heart muscle. So how can it be that the patient doesn’t notice anything?
The Heart Foundation finds two explanations for this: On the one hand, the infarction very small and thus bring only minor symptoms that are hardly noticed or not noticed at all.
On the other hand, patients suffer from diabetes. Because the elevated blood sugar levels damage nerves and thus the nerves in the heart can be affected, it is possible that the pain signals triggered by a heart attack are not transmitted. For this reason it is possible that the person concerned has a not perceiving the infarctioneven if he is big.
Silent heart attack: These are the risk groups
That German Red Cross states that through years of exposure to risk factors affect the heart attack. These are for example: obesity, high blood pressure, smoking, lack of exercise, such as too high cholesterol levels.
Icelandic Heart Society Hjartavernd initiates “Iceland MI study”
A medical team had since 2004 more than 900 elderly Icelanders in one long-term study by means of ECG and cardiovascular magnetic resonance imaging (MRI) examined – with surprising result: During only ten percent of the subjects aged 67 to 93 had suffered a diagnosed heart attack, the researchers were able to 17 percent Detect signs of a silent heart attack. The number of undetected heart attacks was thus significantly higher than that of detected infarctions. So gone nearly two-thirds of heart attacks are subclinical and are overlooked in routine medical examinations.
A current evaluation of the long-term data, the dr Tushar Acharya and colleagues from the US National Health Service NIH in Bethesda together with researchers from the Icelandic Heart Society in the journal JAMA Cardiology published, shows how dangerous silent heart attacks are:
The mortality rate of patients with silent heart attacks is three percent in the first three years of the study, just as high as that of subjects without heart attacks and thus significantly lower than those with “normal” heart attacks (nine percent). From the fourth year, however, the mortality increased noticeably in the silent heart attack group and approached the level of the heart attack group. After ten years of observation, the mortality rate in patients with silent myocardial infarction was 49 percent statistically hardly of subjects with ordinary heart attack (51 percent) to distinguish and was significantly different from people without a heart attack (30 percent).
EKG signs not harmless
After so-called silent heart attacks, there is a risk that heart failure will develop over time. A corresponding association was found in an analysis of 9,242 study participants Atherosclerosis Risk in Communities (ARIC) shown.
In the current analysis, silent myocardial infarctions were increased by 35 percent risk of heart failure associated. “Therefore, it is possible that silent heart attacks represent a milder form of the manifest heart attack or the early changes before the development of a myocardial infarction or heart failure,” say the physicians.
It must now be clarified whether a therapyas used in overt myocardial infarction.
Preventing a silent heart attack: reducing risk factors
The advice of the Frankfurt cardiologist Thomas Voigtlnder: “There are five risk factors for a heart attack: Smoking, high blood pressure, diabetes, high cholesterol and a genetic predisposition. Anyone who has one or more of these points should have a thorough examination, minimize the risk factors and have any existing heart damage treated.” Anyone who does not have any of the risk factors will most likely suffer neither a silent nor a typical heart attack.
When constrictions in the coronary arteries were detected at an early stage the death of heart muscle tissue and the resulting consequential damage such as a heart attack can be prevented. In order to prevent it right from the start, you should of course also pay attention to your diet. Here are 9 foods that will drastically lower your heart attack risk by clearing your arteries.
