Coronary heart disease (CHD) can cause heart arrhythmia, heart insufficiency or heart attack. All the more important is an early, reliable diagnosis that helps to treat it and to reduce risk factors. But what is the best method for diagnosis? A recent study found that functional imaging methods can often spare patients the trouble and risks of a coronary angiography.
Myocarditis: more specific diagnosis thanks to molecular imaging
01/09/2017
There are many causes of myocarditis or inflammation of the heart muscle. Oftentimes, the culprits are viruses or bacteria and sometimes even an acute heart attack. Regardless of the cause, it creates a challenge for cardiologists: a diagnosis tends to be only nonspecific without a biopsy. A cardiac MRI and molecular imaging promise to provide assistance.
Collect Data? Utilize Data! – The Blessings of Big Data
01/03/2017
Genome data, MRI images, and blood test results – data collected in the medical sector is not only very heterogeneous but also extremely extensive. However, it is important to not only collect this data but to also utilize it. After all, processed, linked and analyzed data provides many opportunities in research, hospital management and ultimately also for the individual patient.
Sodium intake and blood pressure: too much salt is bad for you. What about too little salt?
01/12/2016
Common salt – or sodium chloride – is essential as a stimulant for nerve conduction. What is more, sodium ions also regulate the water balance in the body. Yet when it came to salt consumption, for the longest time the rule was "less is more". However, a recent study publication calls this belief into question.
Heart attacks in diabetics – a special danger
01/12/2016
Diabetics are not only schooled in getting a handle on their blood glucose levels, but also in looking out for possible complications. One complication of diabetes is nerve damage. It is often responsible for the so-called "diabetic foot". Something many people are not aware of is that the heart can also be put at risk by nerve damage.
Individualized sports medicine: training by design
22/06/2016
Exercise makes you healthy – oftentimes even when you are sick. That’s why doctors hardly ever recommend taking a break from it. Even patients who are about to receive a heart transplant can benefit from sports. As is so often the case, the dose makes the poison. We asked sports medicine physician Prof. Martin Halle, what people need to consider.
Cardiac insufficiency: early diagnosis with ultrasound
02/05/2016
Heart failure or cardiac insufficiency presents an extra strain on patients because it severally limits everyday performance and deprives them of energy. Due to their intense need for movement, children are particularly strongly affected. However, the disease is frequently not detected until the physical performance is already declining. An early diagnosis could prevent this.
Big data in cardiology: IT platform to manage "flood of data"
01/05/2016
In addition to patient counseling and clinical diagnostics, the lion’s share of a cardiologist’s work consists of collecting data to be able to better treat future cases based on the gathered information. Until now, this data was recorded in Excel spreadsheets or many other communication platforms. A software is designed to facilitate a cross-industry exchange.
Ultrasound: four dimensions for pediatric cardiac diagnostics
01/03/2016
Fortunately, only a handful of newborns are affected by them, though this determines if not the rest of their lives then, at least, the first few years of affected children: congenital heart defects. After the necessary surgeries, the small patients repeatedly need to return for checkups. Until now, these were conducted using MRI scans. 4D ultrasound can be an alternative.
Atherosclerosis: Getting to the root of the problem with a turbo gene
09/02/2016
Many people suffer from atherosclerosis, especially in developed countries. The buildup of fatty deposits inside the arterial blood vessels leads to strokes and heart attacks. Now, a new method is designed to get to the root of the problem, and with the help of nanoparticles inject new turbo replacement cells into the blood vessels which are intended to exert their curative effect.
Different specialties, one goal – treating children right
01/02/2016

Artificial heart valve: "The structure is meant to be broken down again by the body at a later point."
08/01/2016
There are various artificial heart valves available for children, but they have one essential drawback: they need to be replaced because the children are still growing. The artificial valve, on the other hand, remains the same size – and subsequently becomes too small. This is why an artificial heart valve that grows over time would be ideal.
A wearable to draw a complete picture of the heart
01/09/2015
Smartphone apps and wearable sensors have the potential to help people make healthier lifestyle choices. Self-monitoring therefore is one of the core strategies for changing cardiovascular health behaviors.

03/08/2015
Nuclear medicine physicians use so-called gamma cameras for myocardial perfusion scintigraphy. The devices record radioactive substances that are injected into the patient and show changes in the heart muscle (myocardium). Now a new gamma camera is able to record images faster and by using much less radiation.
ECG measurements: "Our chest strap moistens itself"
01/07/2015
When measuring myocardial activity, it is important for the skin to always stay moist under the electrodes of the ECG. Only then can data be consistently transferred. Athletes have an easier time with this: they are used to sweating. This is a lot harder for older patients.
Transcatheter Pacing System: The world’s smallest cardiac pacemaker
01/07/2015
In the case of cardiac arrhythmia, the normal heart rate gets out of balance due to various reasons. In some cases, it is necessary to implant a cardiac pacemaker. Just like with any intervention, this type of surgery also involves risks. In the worst-case scenario, this can lead to abnormal wound healing or obliteration of the vascular system.
Wanted: rapid test to prevent deep vein thrombosis
01/07/2015
Deep vein thrombosis is not just a risk factor for frequent flyers but also for wearers of cardiovascular implants and newly operated patients. Blood thinners prevent these dangerous blood clots from forming, but they need to be carefully adjusted and do not work the same way in every patient. A detailed analysis of platelets (thrombocytes) could prevent complications in the future.Vascular health in athletes
02/06/2014
"Sports are good for your health", as the saying goes. Regular exercise promotes the health of our blood vessels and prevents vascular diseases. However, many years of competitive sports can also have negative effects on vascular health and increase the risk of myocardial infarction. Prof. Martin Halle of the Technical University Munich explains at MEDICA.de what athletes need to pay attention to.Football: "We want to globally determine deaths for the first time"
02/06/2014
Sudden deaths of football players make headlines time after time: competitive athletes who are the idols of many people die just when they are on the playing field and in the limelight. Congenital heart defects often cause their death. Sports physicians and FIFA now plan to ascertain data that can help improve preventive examinations in competitive football.
