One common theme is the struggle for acceptance. Characters with heart disease often face discrimination or are underestimated in the Naruto world, so they have to fight to be seen as capable ninjas. For example, in many fanfics, they have to prove themselves during missions.
Another one is 'Heart Disease and Hidden Powers'. In this fanfiction, the main character's heart disease is somehow linked to a hidden power within them. It's a unique take as it shows how the character tries to control this new - found power without straining their already weak heart.
Well, having a heart disease would likely make Naruto more cautious. He might not be as impulsive in battles or training, as he has to think about his health. This could lead to him developing more strategic thinking rather than relying solely on his brute strength.
I'm not sure if there are extremely popular ones specifically centered on heart disease attacks. However, there could be some niche fanfictions out there. It's a rather unique topic in the 'Naruto' universe. Usually, more common themes like battles and power - ups are more popular, but some fans might be interested in exploring how medical issues would play out in the 'Naruto' world.
Perhaps in a fanfiction, an enemy uses a special jutsu that causes heart disease attacks among the villagers. This forces the ninja of the Hidden Leaf, including Sasuke and Naruto, to find a way to counter the jutsu and save their people. It would be a race against time to find an antidote or a way to reverse the effects of the heart - attacking jutsu.
Well, in some Naruto fanfictions, a disease could be used to create a really unique plot. For instance, if a disease was created that specifically targeted the Kekkei Genkai holders. It would force the different clans to work together to find a cure. This would be a huge shift from the usual clan rivalries. Maybe the disease was created by a rogue ninja who wanted to wipe out all those with special bloodlines to gain power for himself.
Sakura would probably be the first one to help. She's a medic - nin, after all. She has the skills to monitor his condition and develop treatment plans.
The Department of Cardiology mainly looked at cardiovascular diseases, including cardiovascular disease, high blood pressure, cardiac arrest, dilated dilated heart disease, heart valve disease, heart disease, and so on.
Sasuke would probably be in denial at first. He has always seen Naruto as a rival and a strong force. But once he accepted the reality, he would do whatever it takes to help, maybe even going on dangerous missions to find a cure. He would also feel a sense of guilt if he had ever underestimated Naruto because of the disease.
In a Naruto bloodline and disease - related fanfiction, the story might revolve around a hidden bloodline trait that is considered a 'disease' by the ninja villages. Say, a bloodline that gives uncontrollable power surges but at the cost of the user's health. A group of outcast ninja with this bloodline could be on a journey to prove that they are not a threat but rather an asset, all while trying to find a way to control this so - called disease within them.
