21st Century Necromancer

Since they had moved in together, Yu Chen and Hiromi Jounouchi naturally got up together in the morning, made breakfast together, and after breakfast, went to work together.

The first time taking the subway to work with his girlfriend made Yu Chen feel somewhat unaccustomed, but seeing his girlfriend's smiling face so close, he couldn't help but feel a sense of subtle happiness.

"Why are you staring at me like that? Make sure to watch where you're going when you walk!" Feeling Yu Chen's gaze on her, Hiromi Jounouchi flashed him a smile and reminded him.

"It's just that going to work with you for the first time feels a bit unusual. I used to go alone, and now suddenly having someone by my side is quite peculiar," Yu Chen smiled back at Hiromi Jounouchi before turning his gaze forward.

Seeing Yu Chen in this state, Hiromi Jounouchi couldn't help but smile: "Well, you'll have to get used to it from today onwards, because from now on... I'll be accompanying you to work."

Hiromi Jounouchi's words made Yu Chen chuckle, though he shook his head, laughingly admitting that he couldn't keep his feelings secret while also adjusting his mood, as he and Hiromi Jounouchi walked into the hospital together.

Even in the morning, the hospital was crowded with people. Many of the doctors and nurses who saw Yu Chen and Hiromi Jounouchi arriving for work together were surprised. Although they knew about the couple's relationship, their public arrival together still attracted many gazes, which made Hiromi Jounouchi slightly embarrassed. Nevertheless, she courteously greeted the people she knew.

While the two of them were greeting acquaintances on their way to the office, suddenly, a man in the waiting area clutched his chest and collapsed to the ground. The woman who appeared to be with him immediately started shouting in panic: "Husband, what's wrong with you? Husband! Someone help! Quickly, someone! Save him!n/o/vel/b//in dot c//om

Save him!"

Witnessing this scene, Yu Chen and Hiromi Jounouchi exchanged a glance and, putting aside their affection, rushed over together.

"What happened?" Yu Chen quickly laid the man flat on the ground, unbuttoned his shirt collar and loosened his belt. He then gently rubbed the man's chest while shouting to the nurses who had gathered around, "Stretcher! Get the emergency room ready! Quickly!"

"Yes!" The nurse, upon hearing Yu Chen's command, swiftly acknowledged and ran to fetch a stretcher, also notifying the emergency room to prepare.

While Yu Chen was dealing with the emergency, Hiromi Jounouchi also began asking the woman: "Don't panic, we are doctors, we'll save him! Does he have a history of heart disease?"

"You're doctors? Please, you must save him! I beg you, save my husband!" The woman was visibly agitated as she pleaded, clutching at Hiromi Jounouchi's hand. After Hiromi Jounouchi inquired repeatedly, the woman explained, "My husband has been working abroad. Over a month ago, he told me he had constant chest pain that worsened with exertion.

After returning to the country this month because the pain had stopped, we didn't pay much attention to it. He's been with me these past few days until yesterday he suddenly complained of throat pain, coughing all night without any improvement, so I brought him here today for a checkup... Doctor, what's wrong with my husband? He was fine yesterday! Please, you must save him!"

Hearing the woman's words, Yu Chen understood immediately that the man was likely suffering from a heart attack. While he continued to administer first aid, he said to Hiromi Jounouchi, "Hiromi, tell the emergency room to prepare for cardiac angiography, and get an operating room ready for a cardiac stent placement!"

"Got it!" Hiromi Jounouchi also recognized the severity of the situation. After calming the woman down, she handed her over to a nurse nearby and then quickly ran towards the emergency room.

In the operating room, Yu Chen, who had already changed into surgical attire, was staring intently at the screen in front of him, carefully controlling his movements.

The man had been diagnosed, without a doubt, with a myocardial infarction, and it was a very severe occlusion of the left anterior descending (LAD) artery.

The LAD artery, a branch of the coronary artery located between the ventricles, dubbed the "widow maker." Why is a vessel given such a name? It's because lesions in this vessel tend to occur in middle-aged men between 30 and 60 years old. In times when medical treatment wasn't developed, many a middle-aged man's life was claimed directly by this vessel, leaving many women widowed.

On the screen before Yu Chen was the heart of the man who had just suffered a sudden heart attack. From the shadows, one could clearly see that the vessel meant to supply blood to the heart had completely ceased functioning, being thoroughly occluded, while on the side, collateral circulation had formed, barely supplying the myocardium with blood.

This was also why the man had initially complained of chest pain and then felt no pain afterward. The initial chest pain was due to the issue in the LAD, leading to ischemia and hypoxia of the myocardium.

His subsequent lack of pain was because, after the complete occlusion of the LAD, the right coronary artery had formed collateral circulation, supplying blood to the occluded LAD and temporarily alleviating his myocardial ischemia.

However, this was by no means a good thing, because even with collateral circulation, no one knew how long it would last. If the collateral circulation failed to sustain, under the occluded LAD conditions, the man's heart could suffer massive myocardial necrosis at any moment or even trigger sudden death!

What Yu Chen was doing at that moment was reopening the occluded LAD for the man, restoring blood supply to his heart.

To reopen an occluded vessel involves inserting a very thin catheter into the site of occlusion and then using an inflatable rubber balloon to expand the occluded area.

Depending on the severity of the condition, consideration also has to be given to whether to place a vascular stent. Generally, if the situation is not severe and only vessel narrowing has occurred, implantation of a vascular stent may be unnecessary.

A vascular stent is a commonly used medical device in cardiac interventional surgery that functions to clear arterial vessels, also known as a coronary artery stent. After using a balloon to expand the occluded or narrowed section of a vessel, the stent can be inserted through the catheter into the expanded area, to hold the vessel open and prevent re-occlusion.

However, the installation of a vascular stent does not guarantee that all is well and without impact.

If, after a stent has been implanted, the patient fails to adhere to medication regimen, does not change unhealthy lifestyle habits, and neglects proper control of blood pressure, blood lipids, and blood sugar, the originally healthy vessels may develop new lesions. At the site of the implanted stent, restenosis is highly likely to occur.

Nevertheless, the man's vessel was already completely occluded. After dilating the original occluded vessel, without stent support, it would be very prone to re-narrowing.

Therefore, after seeing the blood flow restored in the originally occluded vessel on the screen, Yu Chen turned to the nurse beside him and instructed, "Vascular stent."
