How do I study the cardiovascular system for Step 1 in just 1 week?
Do cardio in 1 fixed order over 7 days, if you have 10–12 hours a day. Day 1: the 18 organisms and 3 drug groups. Day 2 to Day 3 morning: active reading of First Aid pp. 284–328 with the MCQs. Then the Mehlman cardio playlist, then the FA Foundation Anki cardio deck. Days 5–7: UWorld cardio, system-wise, with every miss reviewed in First Aid .
Read this first
This is only for you if you have roughly 10–12 hours a day for studying, and you're an intern or a graduate.
Working, or studying 5–8 hours a day? Keep the same order and stretch the days. Step 1 while working →
Cardiovascular is daunting for 1 reason: students don't do it in a structured way. They open UWorld, score 40%, and decide they are bad at cardio. They are not. They are in the wrong order.
Structure fixes that. Every step below hits the same 46 pages from a different angle, so when you open UWorld on Day 5, it's your 4th pass of those pages, not your 1st.
Day 1 is the one people skip, and it's the one that matters most. Doing the cardio pharmacology from videos takes half a day, 5 to 6 hours. If you invest this time in doing cardiovascular properly, and the pharmacology, you will become invincible , and there is nothing on this planet that can stop you.
And do it last . Start with the easy systems (renal, respiratory, GI), finish every other system, and only then open cardio. Never start your prep with cardiovascular. It's the hardest system, and it stays freshest when it comes last.

Cardiovascular: micro and pharm first
Cardio starts with its own organisms and drugs: 18 organisms and 3 drug groups . Day 1 below does both, hour by hour. These are the full guides for each one.
Microbiology
Cardio micro: the 18 organisms → The cardio list, grouped by class, with the WRWRT method worked on 1 organism
Microbiology by system → Why micro is 9 short lists, 1 per system, and how to run each one
Sketchy Micro in 6 days → The WRWRT method in full, if these organisms are new to you
Pharmacology
Cardiac pharm: the 3 drug groups → Antiarrhythmics, digoxin and the lipid-lowering agents, with the 1 video for each

The plan Cardio in 7 days, hour by hour
Cardio runs in 1 fixed order: micro and pharm, active reading, active application, active recall, then UWorld. Here is every day, block by block.
Clock times assume an 11-hour day: 9 AM–1 PM, 2–6 PM and 7–10 PM, with lunch and dinner in the gaps. Shift the clock to your day. Keep the order.
Day 1 · Micro + pharm The organisms and the drugs, from the 2 pills
9–9:15 AM Watch How to do the CVS system , the University walkthrough.
9:15 AM–1 PM Micro: the 18 cardio organisms, WRWRT. Watch, recall, watch the gaps, read the Sketchy PDF.
2–6 PM Pharm: antiarrhythmics Classes I–IV and digoxin (Sketchy). Each video twice, back to back.
7–9 PM Pharm: lipid-lowering agents (Dirty Medicine), twice. Recommended, not required: the 3 Dirty Medicine lipid metabolism videos first.
9–10 PM Read the cardio drugs in the High-Yield Pharmacology PDF and highlight what didn't stick. Then test: the First Aid Guide MCQs for today's organisms and the cardio pharmacology.
Day 2 · Active reading First Aid Guide, page by page, MCQs on every page

2–6 PM Watch How to watch Mehlman Medical videos (10 minutes), then the Mehlman cardio playlist from the top, in order.
7–10 PM Mehlman, continued. Pause before he answers and answer it yourself.
Day 4 · Mehlman, then Anki Active application ends, active recall begins
9 AM–1 PM Finish the Mehlman cardio playlist. Any gap → that First Aid Guide page, the same day.
2–6 PM FA Foundation Anki · Cardiovascular , all 198 cards. Answer before you flip.
7–9 PM Open the First Aid page of every card you hesitated on. Read the line and a couple above and below.
Day 5 · UWorld cardio Unused · cardio only · tutor mode · 20 questions a block
9–9:30 AM Clear today's due FA Foundation Anki cards first.
9:30 AM–1 PM Blocks 1–2 (Qs 1–40): solve both in tutor mode, log each score, then review every bookmark in First Aid.
2–6 PM Blocks 3–4 (Qs 41–80): solve both in tutor mode, log each score, then review every bookmark in First Aid.

Day 1 Micro and pharm of cardio, from the pills
Open the First Aid Guide → Cardiovascular in the Vault ( what the First Aid Guide is ). You will see 2 pills: Micro and Pharm . Each opens the exact cardio list, and nothing else. Do both today: micro in the morning, pharm in the afternoon .
Cardiovascular in the First Aid Guide on usmlevault.com: its First Aid pages, MCQ count, the micro and pharm pills it has, and the How to do Cardiovascular video.
Micro · 18 organisms · the WRWRT method. W atch the sketch at 1x with no notes → R ecall the whole story in your head, in order → W atch again only the gaps at 1.5–1.75x → R ead the Sketchy PDF for that organism → T est with the First Aid Guide MCQs for that organism.
Bacteria · 9 S. aureus (acute endocarditis) Viridans streptococci (after dental work) S. epidermidis (prosthetic valves) Enterococcus S. gallolyticus (look for colon cancer) S. pyogenes (rheumatic fever) C. diphtheriae Borrelia burgdorferi (Lyme carditis) Treponema pallidum (aortitis) Viruses · 5 Coxsackievirus B Echovirus Adenovirus Parvovirus B19 HIV Parasites · 2 Trypanosoma cruzi (Chagas) Taenia solium Fungi · 2 Candida Aspergillus
Open Cardio Micro → · The Sketchy Micro guide →
▶ How to do Sketchy Micro The efficient method, 15 minutes.
Pharm · the FWRT method. F ind the resource (already mapped for you, below) → W atch each video twice , back to back → R ead the High-Yield Pharmacology PDF after all of them, and highlight only what did not survive → T est in the First Aid Guide → Cardiac → Pharmacology.
01 · Antiarrhythmics, Classes I–IV (Sketchy)
02 · Digoxin (Sketchy)
03 · Lipid-lowering agents: statins, fibrates, ezetimibe, PCSK9 inhibitors, bile-acid resins (Dirty Medicine)
"Doing the pharmacology section from videos is extremely important. It will take you half a day, 5 to 6 hours, to understand them."
Recommended, not required: the 3 Dirty Medicine lipid metabolism videos, watched before the lipid-lowering drugs. The drugs make far more sense after them.
Open Cardiac Pharm → · The full pharm map →
▶ How to complete pharmacology The high-yield pharm strategy, 15 minutes.
Never done Sketchy? Do the same list from First Aid and the First Aid Guide alone. The list does not change, only the source. Every system's micro and pharm →
Why micro and pharm first: when you reach infective endocarditis on p. 318 and the antiarrhythmics on pp. 326–328, you meet them as old friends, not new facts.

Before Day 2 What the First Aid Guide is, and why you read it
First Aid was written to remind you, not to teach you. Every line assumes you already understand it. That is why IMGs spend 3 hours on 1 page, Google half of it, and still remember nothing a week later.
The First Aid Guide on usmlevault.com puts the teaching back into the page. Every cardiovascular page (pp. 284–328) has the same 5 parts:
Focus On: what on this page is high-yield, and what to skip.
Concept Walkthrough: the page in the order you should think about it.
ELI5: each heading in plain English, with the trap the exam sets. What ELI5 is →
How is this tested?: Common Confusion → Core Concept → The Trap → Your Approach. See a real page →
Test Yourself MCQs on that exact page: 234 across cardiovascular (as of October 2026), with a Rule-out button so you practise elimination the way UWorld makes you.
Example: p. 284, Heart morphogenesis. Focus On tells you what matters on this page: cardiac looping and what happens when it fails (dextrocardia), the protein responsible for left-right asymmetry, septum primum vs secundum as a sequence rather than a list, and patent foramen ovale with its clinical consequence.
First Aid p. 284 (Heart morphogenesis and septation) in the First Aid Guide: Focus On, the ELI5s, the video guide, Concept walkthrough, Key takeaways, How is this tested? and Test yourself.
